Why Choose the ABB Sentry BSR11 24VDC 2TLA010040R0200 Safety Relay?
The ABB Sentry BSR11 24VDC 2TLA010040R0200 is a compact safety and expansion relay designed for industrial machine-safety applications requiring dependable relay outputs in a space-saving format. Part of ABB's Sentry BSR safety relay family, the BSR11 can monitor suitable safety devices such as emergency stops directly in the relay supply circuit and can also be used to expand the number of safe outputs available from another safety relay or safety PLC.
Operating from a 24 V DC supply, the BSR11 provides 4 NO failsafe relay outputs with no intentional time-delay function. This combination makes it particularly useful where several downstream safety contactors or machine functions need to be switched simultaneously from a common safety-control signal.
The 2TLA010040R0200 version uses screw-compression connection blocks and is housed in a slim 22.5 mm wide enclosure for DIN rail installation. With an IP20 degree of protection, approximately 2 W power loss and safety performance up to PL e, the Sentry BSR11 provides an efficient solution for new machinery and safety-system upgrades.

Compact Safety Control and Four-Output Expansion
The ABB Sentry BSR11 is designed for applications where a compact relay with multiple safe contacts is required. As a safety relay, it can monitor suitable devices such as emergency-stop switches directly in the voltage-supply circuit. When the required safety conditions are fulfilled, its four normally open failsafe relay contacts can be used within the machine's safety-related control system.
The BSR11 is also particularly useful as a safety output expansion relay. It can be connected to an appropriate safety relay or safety PLC to increase the number of available safe relay contacts, allowing additional downstream contactors or machine functions to be controlled without requiring a separate primary safety controller for each output. The four NO outputs and absence of an intentional time delay make the BSR11 well suited to applications requiring simultaneous direct safety switching.
Typical Applications
- Emergency-stop safety circuits.
- Safe output expansion from ABB safety relays.
- Safety PLC relay-output expansion.
- Control of multiple downstream safety contactors.
- Machine shutdown and power-isolation circuits.
- Production and packaging machinery.
- Conveyor and material-handling equipment.
- Automated manufacturing systems.
- Machine control panels requiring additional failsafe relay contacts.
- Safety-system upgrades requiring a compact four-output relay module.
