Opto 22 SNAP-OAC5 - SNAP Digital (Discrete) Output Module, 4-Channel, 12-250 VAC

The SNAP-OAC5 provides four channels of 12-250 VAC digital (discrete) output, each switching a separate AC load. AC outputs use zero voltage turn on and zero current turn off for transient-free switching. The module has removable top-mounted connectors to provide easy access to field wiring and features channel-specific LEDs for troubleshooting. Optical isolation provides 4,000 volts of transient (4000 V for 1 ms) protection for sensitive control electronics from industrial field signals. All SNAP digital modules operate on 5 VDC control logic. Each module is factory tested twice before shipment. Part of the SNAP PAC System, the module mounts 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. Such an 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.
