ABB 2TLA010050R0000 2 Channel Safety Relay Module

ABB 2TLA010050R0000 SSR10 safety relay module is a DIN-rail mounted, 24 VDC safety relay expansion designed to extend ABB safety controllers by adding a dedicated safety output channel. It provides a single safety channel with three normally open contacts and one normally closed contact (3NO + 1NC), suitable for wiring emergency-stop interlocks, safety gates, and guarded start circuits in industrial automation. The module includes Start/Test and Reset functionality and features a timer function to support controlled sequencing in safety applications, while its safety relay outputs deliver monitored, fail-safe control signals essential for compliant machine safeguarding. Operated from a 24 V DC supply, the device integrates with ABB safety-system installations and is part of the broader 2TLA safety family, with additional variants available (for example 2TLA010050R0001, 2TLA010050R0100) to accommodate different coil voltages and configurations. This expansion module is commonly used to augment the capability of ABB safety controllers in manufacturing environments, enabling reliable interlock and stop-channel topologies in compact DIN-rail enclosures.
