OPT-SNAP-OAC5MA

SNAP-OAC5MA SNAP 4-Ch Isolated 12-250 VAC Digital Output Module with Manual/Auto Switches

The SNAP-OAC5MA provides four isolated channels of 12-250 VAC digital 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 features manual-
on/manual-off/automatic switches that override output from the application and are ideal for testing field device wiring.
 
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 MicroLogix or other RSLogix-based PLC
system, such as ControlLogix or CompactLogix.
 
For easier, faster wiring, see SNAP TEX cables and breakout boards.
