LOCKOUT PROTECTION RELAY
The ICM220 is a low cost lockout protection
module that helps eliminate nuisance
lockouts due to impedance relay failure.
• Low cost lockout relay
• Safety switch monitoring
• Alarm output during lockout
• Helps eliminate nuisance lockouts
• Replaces impedance relays 83 and 93
Mode 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.
• Voltage: 18 to 30 VAC
