Refer to Power Supply on page 36 for details. 3. A shielded transmission cable or a VCTF cable with a thickness of 0.75 mm2 minimum must be used for signal transmission. If the VCTF cable is used, however, the transmission distance will be 10 m maximum regardless of whether or not independent power supplies for the Input and the Output Link Terminals are used. 4. The minimum input time is required for the B7A to read an input signal. 5. Set the timer of the PLC to 0.02 s minimum if a normal-speed model is connected to the PLC. 6. For high-speed models, these values are possible without grounding the shielded line.

Connect the power supply to either terminal. 49 G70D-B7A G70D-B7A Precautions General Electric Shock Do not touch charged parts of relay terminals or socket terminals while power is supplied. Doing so may result in electric shock. Wiring Be sure to turn the power OFF before performing wiring. Do not touch the terminal block while power is supplied unless the cover is mounted. Doing so may result in electric shock. Be sure to apply the specified voltage to input terminals. Applying an incorrect voltage may prevent the product from operating with its rated performance characteristics, or may cause damage or burning. Relay Models Do not use the product for loads that exceed the rated values for switching capacity (e.g., switching voltage and switching current). If the ratings are exceeded the product may not be able to operate with its rated performance characteristics due to factors such as insulation failure, contact failure, or contact welding. It may even result in damage to or burning of the relay. The lifetime of relays varies significantly with the switching conditions. Be sure to confirm the required performance characteristics by testing the relay under actual operating conditions, and use the relay at a frequency at which it can perform with the required performance characteristics. Continued use of the relay in a state where it cannot maintain the rated characteristics may eventually result in damage to the insulation between circuits or burning of the relay. Do not use the product in locations subject to flammable or explosive gases. Doing so may result in fire or explosion due to the arcing that accompanies the switching mechanism and heating up of the relay. No-contact Output (Transistor, Power MOS FET Relay, and SSR Output) Do not use the product for loads that exceed the rated output current. Doing so may damage output elements and result in short-circuiting or open circuits. When using the product for DC inductive loads, connect a diode that will prevent reverse voltages. Not doing so may damage output elements and result in short-circuiting or open circuits. Correct Use Link Terminals with Relay Outputs This Link Terminal is for relay output. G70D-R6Rj1-B7A Link Terminals use 24-VDC G6D-1A Relays and G70D-R6Mj1-B7A Link Terminals use 24-VDC G3DZ-2R6PL Relays. When replacing relays, use the yellow Relay Removal Tool at the corner of the screw terminal (except for G7TC). Do not mount or dismount relays with the power supplied. Opening the Front Cover (Rotating Type): Hold the two bottom corners of the front cover (labelled A in the diagram below), and lift upwards to open. 50 Replacing Relays Do not mount or dismount relays with the power supplied. Doing so may result in electric shock or malfunction. When replacing relays, use the yellow Relay Removal Tool at the corner of the screw terminal (except for G7TC).

B7AH B7AH Precautions General Common Precautions The B7AH performs 1-to-1 communications and does not require a communications master. It cannot be connected to CompoBus/S transmission paths from OMRON remote masters. Do not use the B7AH in locations subject to corrosive gases. When using the B7AH in locations where a large amount of static electricity is generated (e.g., molding materials, powder, or fluid materials conveyed along pipelines), install the B7AH at least 1 m away from the source of the static electricity. Line Resistance in the Transmission Path If power and signals are transmitted together along 3-core cable, ensure that the line resistance in the transmission path between Link Terminals is less than 2.5 . (The same value applies even if terminal blocks, connectors, or slip rings are used at points on the line.) If the line resistance rises to a value greater than this, the current flowing to 0 V and the line resistance will cause a large voltage drop, preventing normal transmission and generating an error. As a rough guide, the line resistance with a VCTF cable of thickness 0.75 mm2 will be 2.5 per 100 m. Connection to 10-point B7A Terminals is not possible because transmission signals are not compatible. If there is a possibility of shocks or vibration, prevent the pins being damaged by securing the Link Terminal to the PCB using an (e.g., epoxy-based) adhesive. Do not touch the pins. Doing so may cause deformation. In addition, touching the pins in an ungrounded state may result in damage to internal elements due to static discharge. Use an anti-static mat during work to ensure that the body is in a grounded state. Soldering When soldering using a soldering iron or a soldering bath, solder in less than 5 s at a temperature not exceeding 260C. Do not use reflow soldering. Cleaning Do not use highly acidic or highly alkaline solvents to clean the PCB. Power Supply Be sure to use the specified power supply voltage. Do not use a power supply that has a large ripple or intermittently generates abnormal voltages. Noise and Miswiring Protection Circuits If there is a possibility of noise interference between the power supply pins (+V and -V or VDD and VSS) or at input or output pins (IN00 to IN15 or OUT00 to OUT15), or if there is a possibility of miswiring the signal pin (SIG) and the positive power supply pin (+V or VDD), include the protection circuits described on page 68. Wiring Do not wire transmission lines parallel to, and less than 10 cm away from, lines carrying high voltages or currents. If transmission lines are installed less than 10 cm away from potential sources of noise, confirm that correct operation is possible before using the Link Terminal in actual operation. Do not perform wiring with the power supply turned ON. Doing so may cause pins to be accidentally short-circuited, resulting in damage to internal elements and communications failure. If the SIG pin and the positive power supply pin or the VDD (+5 V) pin are shorted during communications, the Link Terminal will malfunction and normal communications will not be possible. Confirm that power lines are not shorted before turning ON the power. Be sure to apply the specified power supply to the power supply pins (positive, negative, VDD, and VSS). Applying excessive voltages (e.g., 100 VAC) will cause the Link Terminal to malfunction and normal communications will not be possible. Shorting (no-load state) the OUT pins of Output Link Terminals during communications will cause the Link Terminal to malfunction. Be sure to connect a load within the specified load current range. When measuring the current with a tester, measure with the load supplied. Recommended Cables Normal-speed Models Cabtire Cables With a single power supply connected to Input or Output Link Terminal: 0.75-mm2 VCTF cable x 3 With independent power supplies connected: 0.75-mm2 VCTF cable x 2 The following cables can also be used: Twisted-pair Cables (If only a single power supply is used, a conductor of thickness 0.75-mm2 min. is required.) Transmission distance: 100 m max. High-speed Models Shielded Cables Use cables for which the cross-sectional area of the conductor is at least 0.75 mm2. 71 B7AC Link Terminals with Sensor I/O Connectors Water-resistive Transmission Unit Compact and satisfies the requirements of IP67.

If sensors are used for input, the following input circuits are required. Two-wire DC Sensor Input If a two-wire DC sensor is used for input, current limit resistor R1 and leakage current diverter R2 are required as shown in the diagram below. The following table lists R1 and R2 values for the E2E-XD-N Two-wire DC Proximity Sensor (with a current leakage of 0.8 mA maximum, a residual voltage of 3 V maximum, and a minimum control output current of 3 mA). Input with B7A and Common Power Supply (12 to 24 VDC) (10-point Modular Model only) The 10-point modular model has an input voltage range of 0 to 5 VDC. If a common power supply is connected, current limit resistor R3 is required as shown in the diagram below. Use the following formula to calculate the value of R3. R3 = Supply voltage VS (V) - 1.4 (V) - 2,200 () Input current (2 x 10-3 (A)) Vs (12 to 24 VDC) + Interior of B7A Supply voltage 12 V 24 V R1 1,800 5,600 R2 820 820 IN 2.2 k R3 Intemal circuit Input Interface (E2E-XD-N) - + R1 Interior of B7A IN R2 Intemal circuit Two-wire DC proximity sensor Note: The 16-point module's input voltage range is 0 V to the power supply voltage.

General Modular Models Each terminal of the B7A-series should be used for only single signal transmission without a transmission host. The B7A-series cannot be connected to OMRON's SYSMAC BUS Remote I/O System. Avoid places subject to corrosive gasses or continual shock and/or vibration. If high-level electrostatic discharge is generated at the installation site (e.g., for transfer of a molding material, powder, or liquid through a pipe), separate the Link Terminals as far as possible from the source of the electrostatic discharge. If the Input and Output Terminals are connected via a three-conductor cable to transmit signals with a single power supply (i.e., the power supply is connected directly to one of the Link Terminals and indirectly to the other), the transmission distance greatly varies with the diameter of the cable. This is due to the potential difference between the current on the 0-V transmission wire and on the 0-V I/O transmission line caused by the resistance of the cable. By increasing the diameter of the cable (decreasing its resistance), the transmission distance can be increased. By reducing the resistance of the transmission path to 2.5 or less for example (i.e., increasing the thickness of the wire to 1.25 mm2 or more), a transmission distance of 160 m will be achieved. It is recommended that a switch for minute loads be connected to the 16-point screw terminal model because there is a contact input current of only 3 to 6 mA to the model from the connected switch or relay. The Output Terminal has an error of 300 ms maximum after the Output Terminal is turned on. The user should be well aware of this before using error outputs. Note: The 10-point and 16-point models cannot be connected to each other because their transmission signal data formats are not compatible. Soldering (with an soldering iron or in a soldering tab) must be completed within 5 s at a temperature of 260C or less. The supply voltage must be within the operating voltage range. Do not use a power supply which generates irregular voltages or large ripples. Do not apply a strong acidic or alkaline solvent to the printed circuit board for removal of the flux. The module of the B7A 10-point model is not of closed-mold construction. The solvent must not remain on the bottom of the module after the module is cleaned. The module of the B7A 16-point model is of closed-mold construction. The input and output circuits are not insulated. If Link Terminals are influenced by external noise, use photocouplers to insulate the I/O circuits. Screw Terminal Models Apply a torque of 0.78 to 1.18 N S m to tighten wiring terminals. Hold both edges of the terminal cover to open it. If the Input or Output Terminal is mounted to a panel with screws, apply a torque of 0.59 to 0.98 N S m to tighten the screws. Terminals with PLC Connector Models Apply a torque of 0.78 to 1.18 N S m to tighten wiring terminals. Be sure to disconnect the connector unit from the PLC's I/O connector unit when wiring the screw terminals in order not to impose excessive force on the PLC's I/O connector unit. Use the B7A in combination with a PLC correctly, otherwise the B7A may be damaged. The following are correct combinations. B7A Input Unit and PLC Output Unit B7A Output Unit and PLC Input Unit Wiring Separate the transmission lines from high voltage or power lines as far away as possible and do not wire the transmission lines in parallel with high voltage or power lines. If Link Terminals are used near a device that generates noise, make sure that the Link Terminals do not malfunction due to the noise generated from the device. Make sure to turn off the Link Terminals while wiring in order to avoid a short-circuiting accident that may damage the internal element(s) of the Link Terminals. Link Terminals will malfunction if the SIG terminal is short-circuited with one of the power terminals or Bjj terminal. Before turning the power on, make sure that the SIG terminal is not short-circuited with these terminals. Before checking the insulation resistance of the transmission path, disconnect the wires from the Link Terminals. If the OUT terminal and positive power terminal of the Output Link Terminal is short-circuited during signal transmission, the Link Terminal will malfunction. Apply an appropriate load between these terminals. When measuring the current, use a multimeter without disconnecting the load. 105 B7A B7A Recommended Cables For B7A with Normal I/O Delay Cabtire Cable When a single power supply is connected to either the Input Terminal or Output Terminal: VCTF 0.75 x 4 C (B7AM) VCTF 0.75 x 3 C (B7A/S/C) When independent power supplies are connected to both Link Terminals: VCTF 0.75 x 3 C (B7AM) VCTF 0.75 x 2 C (B7A/S) The following cable can also be used. Twisted Pair Wire When a single power supply is connected to either the Input Terminal or Output Terminal, the thickness of the wire must be 0.75 mm2 or greater. Transmission distance: 100 m max. For B7A with Short I/O Delay Shielded Wire Use a shielded wire with a thickness of 0.75 mm2 min. Color Screw Terminal Models Marked "IN" in white ink. The background is red.

Power Couplers B7AP Allows Wireless Transmission of ON/OFF Signals from Input Devices and Power to Input Devices Makes use of electromagnetic coupling to transmit input signals to the B7A Output Unit and transmit power to the B7A Input Unit without wiring. Supplies power to the B7A Input Unit, which means it does not require an independent power supply, and receives input signals from rotating and moving devices. Wireless signal and power transmission through a nonmetal object (such as plastic or glass) is possible.

The surface temperature varies with the load of the sensing device connected to the B7AP-M1 Power Coupler and the transmission distance. Do not subject the head of the B7AP-S1 or B7AP-M1 Power Coupler to excessive shock with hard objects. Correct Use Handling Use the B7AP-S1 and B7AP-M1 Power Couplers with the available B7A Link Terminals. Refer to page 21, B7A Models. The M7E-12jj Display Unit, M7E-20jj Display Unit, and B7A Link Terminals with an I/O delay time of 3 ms cannot be used with the B7AP-S1 or B7AP-M1 Power Coupler. Use the LOAD-OFF model for the B7A Output Unit to be connected to the B7AP-S1. When using a model that allows selection of error processing, set to the LOAD-OFF mode. This turns OFF signals right before an occurrence of a transmission error and prevents unexpected signal transmission when the transmission error is cleared. Separate the Power Couplers 81.5 mm min. away from each other. The distance between the Power Couplers on standby must be 30 mm or more. 30 mm min. Do not use the B7AP-S1 or B7AP-M1 Power Coupler outdoors unless it is properly protected. The B7AP-S1 and B7AP-M1 Power Couplers are products meeting the requirements of IP67. The B7AP-S1 or B7AP-M1 Power Coupler cannot be, however, used in water or oil. Keep the heads of the B7AP-S1 and B7AP-M1 Power Couplers free from dust, otherwise improper signal or power transmission may result between the Power Couplers. Mounting Do not supply power to the B7AP-S1 or B7AP-M1 Power Coupler while connecting the Power Couplers to the B7A Link Terminals. Connect the Power Couplers to the B7A Link Terminals correctly, otherwise the internal circuits of the Power Couplers may be damaged. The SIG terminal must not contact with the power supply terminals, otherwise the internal elements may be damaged and normal transmission may not be possible. Use nuts and serrated toothed washers and tighten the nuts to mount the B7AP-S1 and B7AP-M1 Power Couplers. The tightening torque applied to each of the nuts must be 39 N S m maximum. The mounting position will change and improper signal or power transmission may result between the Power Couplers if the nuts are not tightened properly. 39 NSm max. Brown(+) Black(SIG) Correct Blue(-) Contact Brown(+) Black(SIG) Blue(-) Incorrect Black(SIG) Brown(+) Transmission Distance for Stable Signal and Power Transmission The B7AP-S1 Power Coupler has a gauge that is used to adjust the transmission distance between the B7AP-S1 and B7AP-M1 Power Couplers. Use the gauge to adjust the transmission distance to 8 mm, make sure that the green operation indicator of the B7AP-M1 Power Coupler is lit, and the B7A Output Unit has no error output before operating the Power Couplers. Incorrect Blue(-) 8 mm Gauge Wire the cables of the B7AP-S1 and B7AP-M1 Power Couplers through independent metal conduits to prevent the Power Couplers from being influenced by noise if there are power or high-tension lines nearby. Test the Power Couplers and make sure that the Power Couplers operate normally before they are put in actual operation.
