The ABB 2TLA010033R0000 (series BT50 24DC Safety Relay) is a safety/expansion relay intended to provide additional safe relay outputs for industrial safety circuits. It can be used to expand the number of safe outputs available from a primary safety device or safety controller, making it easier to control multiple contactors or actuators from a single safety input. The module is powered by 24 V DC, mounts on a DIN‑rail, uses screw terminal connections, and is suitable for applications such as emergency‑stop circuits, safety‑interlocks, gate/door guarding, and safety‑related output expansion.
