OPT-SNAP-IAC5A

SNAP-IAC5A SNAP 4-Ch 180-280 VAC Digital Input Module

The SNAP-IAC5A provides four channels of 180-280 VAC digital input. Each channel senses the on/off status for AC
voltages from sources such as proximity switches, push buttons, or auxiliary contacts. The module has removable top-
mounted connectors for easy access to field wiring, as well as channel-specific LEDs for convenient troubleshooting.
 
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.
