SNAP Mechanical Power Relay Output Modules Features Description SNAP mechanical power relay output modules offer four channels for switching loads of up to 6 amps at 250 VAC or 30 VDC. These modules handle more current than other SNAP output modules. Each contact can carry 6 amps, and having more than one channel on at the same time does not reduce the amount of power each channel can carry. These are form C modules, so each of the four mechanical contacts can be wired as normally open or normally closed. Fusing is not provided; you must provide fusing when wiring the module. SNAP mechanical power relay output modules provide channel-to-channel isolation. These modules can mechanically switch either AC or DC loads, potentially reducing the number of modules needed. Additionally, SNAP mechanical power relay output modules offer little or no leakage current when the contacts are open. In contrast, possible leakage current in solid-state SNAP AC output modules might cause an electronic input to stick in the ON state. These modules are suitable for piloting electronic coil contactors. NOTE: These modules may not be suitable for low-level switching. NOTE: Transient protection is recommended for inductive loads. For DC loads, install a reverse-biased diode, such as an 1N4005 (or equivalent) at the load. When using the SNAP-OMR6-C, you must provide transient suppression at the load. If long wire runs are used, transient suppression is required at the terminals of the module as well. NOTE: SNAP-OMR6-C modules manufactured prior to March 2014 have four black field wiring connectors; newer modules have a single large gray connector as shown above. Field connector wiring and module function are identical. Note torque differences in "Specifications" on page 3. Compatibility Part of the SNAP PAC System, these modules mount on a SNAP PAC rack with a SNAP PAC brain or rack-mounted controller. Analog, digital, and serial I/O modules can all be on the same rack. This kind of I/O unit is also well suited for PC-based control or for use as intelligent remote I/O for an Allen-Bradley PLC system. PAC Project--The SNAP-OMR6T-C is supported in PAC Project R9.4009 and higher. The SNAP-OMR6-C is supported in PAC Project R9.2 and higher. Brains--SNAP mechanical power relay output modules are compatible with all SNAP PAC brains and rack-mounted controllers, including both standard wired models and Wired+WirelessTM models. Part Number Description SNAP-OMR6T-C NOTE: For very high inductive loads, additional transient protection is recommended.

Specifications and wiring diagrams for the obsolete SNAP-OMR6-A are included in this data sheet for reference only. 3. Installation 4. The following diagram shows part of a SNAP mounting rack. Modules snap securely into place in the row of connectors on the rack. Each module connector is numbered, starting with position zero. Processor connector Module position zero Module connectors Retention bar 5. Position the module over the module connector, aligning the small slot at the base of the module with the retention bar on the rack. When positioning modules next to each other, be sure to align the male and female module keys at the tops of the modules before snapping a module into position. With the module correctly aligned, push on the module to snap it into place. Use standard 4-40 x 1/2 truss-head Phillips hold-down screws (provided) to secure both sides of each module. CAUTION: Do not overtighten screws. Torque for holddown screws: 4 in-lb (0.45 N-m) Follow the wiring diagrams on page 5 to attach the module to field devices. Torque for connector screws: 1.7 in-lb (0.2 N-m) Modules require a special tool (provided) for removal. Form 1967-160920 SNAP Mechanical Power Relay Output Modules SNAP-OMR6-A A previous module, the form A SNAP-OMR6-A, is no longer available. Use the SNAP-OMR6T-C as a pin-identical, drop-in replacement for this obsolete module. Place the rack so that the module connector numbers are right-side up, with zero on the left, as shown in the diagram above. (If your rack has screw connectors, the screw connectors will be at the bottom.)
