Why Choose the ABB SENTRY USR22P 2TLA010070R0401 Universal Safety Relay?
The ABB SENTRY USR22P 2TLA010070R0401 is a configurable universal safety relay with integrated timing functions designed for monitoring a broad range of machine-safety devices. As part of the ABB SENTRY Safety Relays product group, it supports safety devices with contact outputs, equivalent or antivalent channels, OSSD outputs, two-hand controls, safety mats, safety edges and bumpers.
The SENTRY USR22P operates from a 24 V DC supply and provides 2 normally open (2NO) safety relay outputs plus 2 normally open (2NO) delayable safety outputs. Its multifunction timer can be configured across a 0–999 s range for OFF-delay, ON-delay, Time bypass and Time reset functions, providing extensive flexibility for machinery requiring both immediate and timed safety outputs.
A front-mounted display simplifies configuration and troubleshooting by providing operating information, error codes and an error log, while custom configurations can be protected by password. Combined with selectable manual or automatic reset, push-in spring terminals and a compact 22.5 mm DIN-rail housing, the USR22P provides advanced safety monitoring and configurable timing in a space-efficient industrial module.

Configurable Safety Monitoring with Independent Delayed Outputs
The ABB SENTRY USR22P combines universal safety-device monitoring with separate instantaneous and delayable relay outputs. Its 2NO instantaneous outputs can respond directly to the safety function, while the additional 2NO delayable outputs can be configured for timed operation. This makes the relay particularly useful where different parts of a machine shutdown sequence need to operate at different times.
The integrated 0–999 s multifunction timer supports OFF-delay, ON-delay, Time bypass and Time reset modes with accuracy better than 1%. Combined with its support for contact devices, OSSD outputs, two-hand controls and pressure-sensitive safety devices, the USR22P provides machine builders with a configurable platform for both conventional and more complex safety applications.
Typical Applications
- Emergency stop monitoring with configurable delayed outputs.
- Safety gate and guard switch monitoring.
- Safety light curtains and compatible OSSD devices.
- Two-hand control stations.
- Safety mat, edge and bumper monitoring.
- Controlled machine stopping sequences.
- Timed shutdown and delayed isolation functions.
- Industrial production and assembly machinery.
- Packaging, conveyor and material handling equipment.
- OEM machine building and configurable industrial safety panels.
