DATA SHEET Form 1120-170913 PAGE 1 SNAP POWER SUPPLIES Features > > > > > > Built-in fuse, ON/OFF power switch, and LED indicator Convenient panel mounting; optional DIN-rail mounting Easy connections Wide input voltage range UL approved Factory Mutual approved (except SNAP-PS5U and SNAP-PS24U) DESCRIPTION SNAP power supplies provide the best source of AC or DC power for your Opto 22 SNAP PAC hardware. Packaged in a compact and sturdy housing, SNAP power supplies include a built-in fuse, an LED status indicator, and an ON/OFF power switch for ease of use. The SNAP-PS24 and SNAP-PS24U power supplies are designed for either of two purposes: * To provide primary power for a SNAP PAC S-series controller * To provide 24 volts of DC loop power for SNAP analog modules mounted on a SNAP PAC rack The SNAP-PS5, SNAP-PS5-24DC, and SNAP-PS5U power supplies are designed to provide 5 VDC power for a SNAP PAC rack with an I/O processor (SNAP PAC brain or R-series controller) and I/O modules mounted on the rack. The combination of a rack, processor, and modules is called an I/O unit. Opto 22 recommends using one SNAP power supply for each I/O unit and for each controller. Choose the power supply based on the load required for the I/O unit. See the power requirements tables starting on page 12 for help in determining the power supplies you need. Additional information on using power supplies can be found in the Opto 22 technical note Using Power Supplies with Opto 22 Systems (form #1271, available on our website, www.opto22.com). SNAP-PS5 power supply AC or DC input power connections, as required by the model, are made to a removable terminal strip on top of the power supply. DC output power is then ready to be hooked up to the controller or rack using the attached wiring harness. SNAP power supplies work with Wired+WirelessTM PACs and I/O units as well as standard wired PACs and I/O. Notes for legacy hardware: SNAP power supplies are also compatible with Ethernet-based SNAP Ultimate, SNAP Ethernet, and SNAP Simple I/O, and with serial-based SNAP I/O units such as those with a B3000, SNAP-HA, or SNAP-B3000-MODBUS brain. Part Numbers All SNAP power supplies except the SNAP-PS5-24DC require AC input power. The SNAP-PS5U and SNAP-PS24U accommodate a wide range of AC input voltages, from 100 to 250 VAC. The SNAP-PS5-24DC DC-to-DC power supply requires a 24 VDC input and is ideal for systems using DC backup power. Each SNAP power supply can be mounted in one of two ways: next to the controller or SNAP I/O unit it powers, using the standard panelmounting base, or directly on a DIN rail using the optional 35mm DINrail adapter.

DATA SHEET Form 1120-170913 PAGE 3 I/O UNIT POWER REQUIREMENTS The tables starting on page 12 will help you determine the power supply needs for your system. Copy the power requirements worksheet and complete one for each distributed I/O unit. In addition, keep the following power recommendations in mind. For more help with power supplies, see Opto 22 form #1271, Using Power Supplies with Opto 22 Systems. Use a single power supply per rack In general, we recommend you use an independent, isolated, regulated power supply locally with each rack. Local isolated supplies offer these advantages: * Short supply conductors, which minimize losses * Power redundancy, so the failure of a single supply causes only a single rack failure, not a total system failure * Fewer voltage drops and ground loops (Voltage drops and subsequent ground loops may occur when power is distributed over a large system.) Always use a separate field supply Use a separate power supply for the field side of the I/O. Using the rack supply for field actuation and monitoring defeats the isolation the I/O module offers and therefore increases the chance of a ground loop within the control system. Additionally, a sudden change of current on the field side can cause undesirable voltage fluctuations that may interfere with the controller or I/O unit's operation. Power wiring guidelines * * * * * Use one power supply per I/O unit. Use one power supply per controller. Use 14 AWG wire. SNAP power supplies have short wires to minimize voltage drop. Do not extend the length of the wires. If you power multiple I/O units or controllers from one power supply, use a star wiring topology. Do not daisy-chain power wiring from one device to the next.
