ABB 2TLA010061R0000 Safety Relay is an ABB SENTRY TSR20 safety expansion timer that mounts on a DIN rail and is powered from 24 VDC. It provides three normally open and one normally closed safety outputs (3NO+1NC) with two-channel OSSD, making it suitable for two-handed safety devices and other safety interfaces. The unit uses screw terminals for wiring and features an on-board off-delay timer with selectable delays of 0.5 seconds or 1.5 seconds. A higher-voltage variant exists as 2TLA010061R0100, offering 85-265 VAC/120-375 VDC input while preserving the same 3NO+1NC outputs and TSR20 safety features.
