G4 I/O family
The G4IDC5-SWNC module provides one isolated channel of contact status input, sensing switch opening. The module supplies 15 volts of power to an external dry contact switch.
Each user-supplied switch is connected with two wires. Because these modules include power for the switch, this module is particularly cost-effective when labor costs for wiring external power are high.
Typical applications for the G4IDC5-SWNC include sensing contact opening from sources such as switched status sensors (level sensors, pressure indicators, etc.), magnetic reed switches (used on doors or windows for burglar alarms), snap-action micro switches, the auxiliary switches on motor starters, and most relay contacts.
CAUTION: G4IDC5-SW and G4IDC5-SWNC inputs are not intended to be used with contacts that are connected to any external user-supplied voltage or current.
