SNAP 4-Ch 90-140 VAC/VDC Digital (Discrete) Input Module

Please call (800) 321-6786 to order.

Data Sheet

Production Specification

The SNAP-IAC5 provides four channels of 90-140 VAC/VDC digital input. Each channel senses the on/off status for AC (or DC) 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 Logix PLC system, such as ControlLogix, MicroLogix, or CompactLogix.

If you need Factory Mutual approved modules, see SNAP-IAC5FM.

For easier, faster wiring, see SNAP TEX cables and breakout boards.

Build your system in the SNAP I/O Configurator.
