Opto22 SNAP-IDC5MA

SNAP-IDC5MA SNAP 4-Ch Isolated 10-32 VDC Digital Input Module with Manual/Auto Switches

The SNAP-IDC5MA provides four channels of 10-32 VDC digital input. Each channel senses the on/off status for DC
voltages from sources such as proximity switches, push buttons, or auxiliary contacts. This module features manual-
on/manual-off/automatic switches that override input from field devices and are ideal for testing control applications.
 
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.
