Why Choose the ABB 2TLA010040R0201 Sentry BSR11P Safety Relay?
The ABB 2TLA010040R0201, model Sentry BSR11P, is a compact safety relay and safety output expansion relay designed for straightforward industrial machine-safety functions. Operating from a 24 V DC supply, it provides 4 normally open failsafe relay outputs, giving designers four safety-related switching contacts from a narrow control-panel module.
The BSR11P can monitor safety devices such as emergency-stop devices directly in the voltage supply circuit of the relay. It can also be used as an expansion relay downstream of a compatible safety relay or safety PLC, increasing the number of safe relay outputs available for switching contactors and other safety-related machine-control equipment.
This P version features detachable push-in spring connection blocks for fast and convenient control-panel wiring. Its compact 22.5 mm width, DIN-rail format, IP20 protection and operating temperature range of -25 to +65 °C make the Sentry BSR11P a practical solution where multiple safe normally open outputs are required without occupying excessive cabinet space.

Reliable Safety Monitoring with Four Normally Open Outputs
The Sentry BSR11P is designed for simpler machine-safety functions where dependable electromechanical safety outputs are required. Safety devices such as emergency stops can be connected directly in the relay's voltage supply circuit, allowing actuation of the safety device to remove the safety output condition and initiate the required machine shutdown through the relay's four normally open contacts.
The BSR11P is equally useful as a safe output expansion relay. When a safety relay or safety PLC requires additional physical relay contacts, the BSR11P provides four normally open failsafe outputs for controlling external contactors or other safety-related equipment. The push-in terminal version combines this output capacity with convenient wiring and a narrow DIN-rail footprint.
Typical Applications
- Emergency-stop monitoring circuits.
- Safe output expansion for ABB safety relays.
- Safe output expansion for safety PLC systems.
- Safety-related contactor control.
- Machine shutdown and isolation functions.
- Conveyor and material-handling equipment.
- Packaging and processing machinery.
- Automated production and assembly equipment.
- Machine tools and manufacturing cells.
- OEM control panels requiring multiple normally open safe relay outputs.
