ICM220

LOCKOUT PROTECTION RELAY

All features and speciﬁcations subject to change without notice.

The ICM220 is a low cost lockout protection

module that helps eliminate nuisance

lockouts due to impedance relay failure.

SpecificationsMode of Operation

Upon application of power with the safety switches

closed, the load will energize. If any of the safety switches

open for longer than 600 ms, the fault light will come on

and the load will stay de-energized regardless of the state

of the safety switches. Power must then be removed for

100 ms and safety switches must be closed in order to

reenergize the load, upon which the fault light will be off.

Input

• Voltage: 18-30 VAC

• Frequency: 50/60 Hz

Output

• Relay: SPDT

• Relay Contacts: 2 amps maximum @ 30 VAC resistive

• Power Consumption: 2 watts maximum during lockout
