2TLA010070R0001 ABB SENTRY USR10P Configurable Safety Relay 24 V DC 3NO + 1NC

Why Choose the ABB SENTRY USR10P 2TLA010070R0001 Universal Safety Relay?

The ABB SENTRY USR10P 2TLA010070R0001 is a highly configurable universal safety relay 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 USR10P operates from a 24 V DC supply and provides 3 normally open (3NO) and 1 normally closed (1NC) delayable relay outputs. Its multifunction timer can be configured from 0–999 s for OFF-delay, ON-delay, Time bypass or Time reset functions, giving machine builders greater flexibility than a fixed-function safety relay.

A front-mounted display supports configuration and troubleshooting by providing operating information, error codes and an error log. Custom configurations can be password protected, while manual or automatic reset is selectable to suit the application. Combined with push-in spring terminals and a compact 22.5 mm DIN-rail housing, the USR10P provides advanced safety functionality without requiring excessive control-panel space.

Configurable Safety Monitoring and Timing in One Relay

Unlike a safety relay dedicated to a single input or timing function, the ABB SENTRY USR10P can be configured for a wide range of machine-safety devices and operating requirements. It can monitor conventional contact-based safety devices, OSSD outputs, two-hand controls and pressure-sensitive devices, allowing one relay type to cover numerous applications across a machine or control-system design.

Its integrated 0–999 s multifunction timer further extends this flexibility by providing OFF-delay, ON-delay, Time bypass and Time reset modes. The front display assists commissioning and troubleshooting, while password protection can help prevent unintended changes to a completed configuration. This combination makes the USR10P particularly useful for machine builders seeking to standardise on a configurable safety relay platform.

Typical Applications

• Emergency stop monitoring.
• Safety gate and guard switch monitoring.
• Safety light curtains and compatible OSSD devices.
• Two-hand control stations.
• Safety mat monitoring.
• Safety edges and pressure-sensitive bumpers.
• Timed machine-safety functions and controlled stopping sequences.
• Industrial production and assembly machinery.
• Packaging, conveyor and material handling equipment.
• OEM machine building and configurable industrial safety panels.
