The ICM Controls ICM220B is an 18-30V Lockout Relay designed to protect compressors by monitoring safety switch inputs. This lockout protection module ensures that if safety switches open for over 600 ms, the load de-energizes and a fault light activates. To re-energize, power must be removed for 100 ms and safety switches closed, resetting the fault. It operates on 18-30 VAC at 50-60 Hz.
Monitors safety switch inputs to protect compressors and eliminate nuisance lockouts.
