Why Choose the ABB SENTRY BSR23P 2TLA010041R0601 Safety Expansion Relay?
The ABB SENTRY BSR23P 2TLA010041R0601 is a compact and reliable safety expansion relay designed to increase the number of safe relay outputs available from a safety relay or safety PLC. As part of the ABB SENTRY Safety Relays product group, the BSR23P provides a straightforward way to expand machine safety circuits where additional positively guided relay contacts are required.
The SENTRY BSR23P features 4 normally open (4NO) and 1 normally closed (1NC) relay outputs, a 24 V DC supply voltage and detachable push-in spring terminals. The push-in connection technology helps simplify control-panel wiring and maintenance while the slim DIN-rail housing conserves valuable cabinet space.
With a width of just 22.5 mm and an IP20 protection rating, the BSR23P is designed for installation inside industrial electrical control panels. It is intended primarily as a safe output expansion device and can be used with suitable safety relays and safety PLCs in machinery and automation systems requiring additional safety-related relay contacts.

Reliable Safe Output Expansion for Machinery
Safety relays and safety PLCs often require additional relay contacts to control multiple contactors, drives or other safety-related actuators. The ABB SENTRY BSR23P provides additional relay outputs for this purpose, allowing the available safe outputs of a suitable upstream safety device to be expanded without requiring a separate safety controller for each additional circuit.
The BSR23P is intended to operate as an expansion relay and must be appropriately monitored by the controlling safety device where required by the target safety performance level. Its 4NO + 1NC contact arrangement provides useful flexibility for controlling safety-related loads and providing auxiliary signalling, while the push-in spring terminals support efficient installation and servicing in industrial control cabinets.
Typical Applications
- Expansion of outputs from industrial safety relays.
- Expansion of safe outputs from safety PLCs.
- Machine emergency-stop safety circuits.
- Safety gate and machine-guarding systems.
- Contactor and actuator control in safety-related circuits.
- Industrial production and assembly machinery.
- Packaging and material handling equipment.
- Conveyor and automated manufacturing systems.
- OEM machine building and control-panel applications.
