Why Choose the ABB 2TLA010040R0001 Sentry BSR10P Safety Relay?
The ABB 2TLA010040R0001, model Sentry BSR10P, is a compact safety relay and safety output expansion relay designed for straightforward machine-safety functions. Operating from a 24 V DC supply, it provides 3 normally open safety relay outputs plus 1 normally closed auxiliary output, making it suitable for both direct safety-device monitoring and expansion of safe outputs.
The BSR10P can monitor safety devices such as emergency-stop devices directly in the relay's supply circuit. It can also operate as an expansion relay downstream of another safety relay or safety PLC, increasing the number of relay-based safe outputs available for controlling contactors, machine actuators and other safety-related equipment.
This P variant uses detachable push-in spring terminals for fast, maintenance-friendly panel wiring. With a narrow 22.5 mm housing, DIN-rail mounting, IP20 protection and an operating temperature range of -25 to +65 °C, the Sentry BSR10P provides a space-efficient solution for industrial safety control cabinets.

Reliable Safety Monitoring and Output Expansion
The Sentry BSR10P is designed for simpler safety functions where dependable electromechanical relay outputs are required. Safety devices such as emergency stops can be connected directly in the voltage supply circuit of the relay, allowing the BSR10P to interrupt its safety outputs when the monitored safety function is actuated.
Where an existing safety relay or safety PLC does not provide enough physical safe outputs, the BSR10P can instead be used as an expansion relay. Its three normally open relay contacts provide additional switching capacity for safety-related control circuits, while the normally closed auxiliary contact can support signalling or monitoring requirements. The push-in terminal version further simplifies installation and servicing within industrial control panels.
