G4IDC5-SW and G4IDC5-SWNC Modules

Description

Each G4IDC5-SW and G4IDC5-SWNC module provides one

isolated channel of contact status input. Each module supplies

13 volts of power to an external dry contact switch. The

G4IDC5-SW senses switch closure; the G4IDC5-SWNC senses

switch opening. Each user-supplied switch is connected with

two wires. Because these modules include power for the

switch, they are particularly cost-effective when labor costs for

wiring external power are high.

Typical switches for use with these modules are 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 currents.
