ABB 2TLA010040R0200 Safety Relay Module 4-Channel

ABB 2TLA010040R0200 Safety Relay Module 4-Channel is a four-channel safety expansion relay (BSR11) designed for ABB Jokab Safety systems. It provides four normally open contacts driven by a 24 VDC coil and is intended for DIN-rail mounting in standard control panels. As an expansion relay, it increases the number of safety-relay outputs available to a safety controller, enabling safe control of additional devices within low-voltage safety circuits. The module features four NO outputs with no time delay, matching ABB's safety-relay performance for quick and reliable signaling across interlocks and guards connected to the SENTRY family. Part of ABB’s safety and expansion relay lineup, this 24 VDC coil device is compatible with other BSR-series modules in DIN-rail mounted safety architectures and is specified for use in 24 V safety circuits. The compact 4-channel configuration helps scalable safety designs without requiring major hardware changes and supports integration with ABB’s safety ecosystem for industrial automation.
