SNAP 4-Ch Switch Status Input Module, Normally Closed
SNAP-IDC5-SW-NC leírás
The SNAP-IDC5-SW-NC module provides four channels of contact status input. The 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. For easier, faster wiring, see SNAP TEX cables and breakout boards.
