Product Introduction
The ABB 2TLA010053R0400 is a SENTRY SSR42 safety relay with a 24 VDC coil, designed for machine safety circuits that require a monitored, force-guided contact set. It sits in the ABB SENTRY family of safety relays, used in industrial safety loops to interrupt power when a guard door, light curtain, or emergency stop is triggered. The 24 VDC control voltage matches standard industrial control voltages, so it drops into a panel without a separate supply rail.
Applications and Environments
This safety relay is intended for machine safety circuits in industrial automation — emergency stop chains, guard door interlocks, light curtain outputs, and two-hand control stations.
