Why Choose the ABB SENTRY SSR10 24VDC 2TLA010050R0000 Safety Relay?
The ABB SENTRY SSR10 24VDC 2TLA010050R0000 is a compact industrial safety relay designed for reliable monitoring of safety devices in machinery and automation systems. Part of the ABB Jokab Safety Sentry range, the SSR10 can monitor safety devices with contacts using one or two equivalent channels, as well as electronic safety devices with OSSD outputs.
The SSR10 provides 3 normally open safety relay outputs and 1 normally closed relay output, giving machine builders a flexible interface between safety devices and contactors or other control equipment. Manual or automatic reset can be selected using the switch on the front of the relay, simplifying configuration for different machine safety requirements.
Operating from a 24 V DC supply, the SSR10 supports applications up to PL e / SIL 3 when correctly incorporated into an appropriate safety system. Its compact 22.5 mm wide enclosure, detachable screw connection blocks and standard DIN-rail mounting make it well suited to modern industrial control panels where dependable safety monitoring and efficient use of cabinet space are required.

Flexible Safety Monitoring for Industrial Machinery
Safety relays such as the ABB SENTRY SSR10 provide the monitored interface between machine safety devices and the equipment responsible for removing hazardous movement or energy. The SSR10 can monitor conventional contact-based safety devices through one or two equivalent channels and can also accept OSSD signals from compatible electronic safety equipment such as light curtains.
The SSR10 combines straightforward configuration with flexible reset functionality. A front-mounted selector allows manual or automatic reset to be chosen for the application, while the 3 NO safety outputs provide multiple switching paths for machine contactors or other safety-related devices. Its high output current capability can also reduce the need for intermediary contactors in suitable applications.
Typical Applications
- Emergency-stop monitoring.
- Interlocked machine guards, gates and hatches.
- Safety switches with one or two equivalent contact channels.
- Safety light curtains with OSSD outputs.
- Safety light beams and other compatible OSSD devices.
- Safe output expansion.
- Industrial machinery and automated production equipment.
- Machine control panels requiring compact safety monitoring.
