  |
outputs use zero voltage turn on and zero current turn off for transient-free switching. The module features channel-
specific LEDs for troubleshooting and includes a connector clamp to prevent sparks.
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.
If you need Factory Mutual approved modules, see SNAP-OAC5-IFM.
For easier, faster wiring, see SNAP TEX cables and breakout boards.
