Why Choose the ABB SENTRY USR10 2TLA010070R0000 Configurable Safety Relay?
The ABB SENTRY USR10 2TLA010070R0000 is a highly flexible configurable universal safety relay and safety timer designed for monitoring a wide range of safety devices in industrial machinery and automation systems. Part of the advanced ABB Sentry safety relay range, the USR10 operates from a 24 V DC supply and provides 3 normally open (NO) and 1 normally closed (NC) delayable relay output.
Unlike application-specific safety relays, the USR10 can monitor safety devices with one or two equivalent or antivalent contact channels, devices with OSSD outputs, two-hand controls, safety mats, safety edges and bumpers. Its configurable architecture allows one relay type to cover numerous machine safety functions, helping reduce the number of different relay models required within an automation system.
An integrated 0–999 s multifunction timer provides OFF-delay, ON-delay, time bypass and time reset functions with better than 1% timing accuracy. A front display assists configuration and troubleshooting by displaying operating information and error codes, while custom configurations can be password protected. Selectable manual or automatic reset further enhances installation flexibility.

Reliable Configurable Safety Control for Industrial Machinery
The ABB SENTRY USR10 provides a universal approach to machine safety by combining multiple monitoring functions and configurable timing capabilities within a single compact relay. It can interface with traditional contact-based safety devices as well as modern OSSD-equipped devices, allowing machine builders to standardise on one safety relay for a broad range of applications.
Its integrated display provides convenient access to configuration and diagnostic information, including error codes and an error log that can simplify commissioning and fault finding. With four selectable timer functions, a 0–999 s adjustment range and selectable manual or automatic reset, the USR10 provides extensive flexibility for both straightforward and more sophisticated machine safety circuits.
Typical Applications
- Emergency-stop monitoring systems.
- Safety gates and interlocking switches.
- Safety light curtains and other OSSD devices.
- Two-hand control stations.
- Safety mats, edges and pressure-sensitive bumpers.
- Timed machine stopping and safety sequences.
- Production, packaging and material handling machinery.
- OEM machinery and configurable industrial safety control panels.
