DESCRIBE

The ABB 2TLA010027R0100 is a safety expansion relay from ABB’s JSR2A series. It is used to expand the number of safe output contacts available when used together with a primary safety relay or safety controller. The module provides additional relay outputs with higher switching capacity, making it suitable for controlling multiple actuators, contactors or devices in safety‑related circuits. It supports dual‑channel input (when used with appropriate safety wiring) and is designed for DIN‑rail mounting, enabling straightforward integration into industrial control panels.
