Why Choose the ABB Sentry BSR23 24VDC 2TLA010041R0600 Safety Expansion Relay?
The ABB Sentry BSR23 24VDC 2TLA010041R0600 is a compact safety expansion relay designed to increase the number of safe relay outputs available from an existing safety relay or safety PLC. Part of ABB's Sentry BSR safety relay family, the BSR23 provides a straightforward way to add additional redundant contacts to industrial machinery safety systems without installing another primary safety controller.
Operating from a 24 V DC supply, the BSR23 provides 4 NO + 1 NC failsafe relay outputs. The module has no intentional timer function, making it suitable for applications where additional safety contacts are required to follow the controlling safety device without a configured time delay.
The 2TLA010041R0600 version features screw terminals and a slim 22.5 mm wide DIN rail housing. With IP20 protection, a net weight of approximately 0.195 kg and safety performance up to PL e when correctly incorporated into the complete safety function, the BSR23 is well suited to machinery, automation and control-panel applications requiring additional safe outputs.

Reliable Five-Contact Safety Output Expansion
The ABB Sentry BSR23 is primarily designed to operate as an expansion relay for a safety relay or safety PLC. When additional safe contacts are required, the BSR23 provides four normally open and one normally closed relay contact, allowing several downstream contactors or machine-control circuits to be switched from the existing safety function. This can simplify control-panel architecture where the primary safety device does not provide enough physical relay outputs for the required machine functions.
Unlike multifunction Sentry safety relays, the BSR23 does not provide dedicated monitoring functions for OSSD devices, two-hand controls, safety mats or guard switches. Instead, the required safety logic is provided by the upstream safety relay or safety PLC, with the BSR23 acting as the safe output expansion stage. The expansion module must be incorporated and monitored according to the safety architecture required by the application to achieve the intended safety performance.
Typical Applications
- Safety relay output expansion.
- Safety PLC relay-output expansion.
- ABB Pluto safety PLC output expansion.
- Control of multiple downstream safety contactors.
- Emergency-stop system output expansion.
- Safety gate and machine-guard shutdown circuits.
- Machine power and hazardous-motion isolation.
- Production and packaging machinery.
- Conveyor and material-handling systems.
- Automated manufacturing and assembly equipment.
- Industrial control panels requiring additional failsafe relay contacts.
