The SNAP-IDC5-SW-NC module provides four channels of contact status input. The Opto-22 module supplies 15 volts of power to an external dry contact switch and senses when the switch opens. Each user-supplied switch is connected with two wires. Because the module includes power for the switch, it is particularly cost-effective when labor costs for wiring external power are high.
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.
