Why Choose the ABB SENTRY SSR32P 2TLA010052R0401 Safety Relay?
The ABB SENTRY SSR32P 2TLA010052R0401 is a compact industrial safety relay with delayed safety outputs designed for monitoring safety devices in machinery and automation systems. As part of the ABB SENTRY Safety Relays product group, it can monitor safety devices with contact outputs using one or two equivalent channels, as well as compatible safety devices with OSSD outputs.
The SENTRY SSR32P provides 2 normally open (2NO) instantaneous safety outputs plus 2 normally open (2NO) delayed safety outputs. The two delayed outputs have a fixed 0.5 s OFF-delay, allowing selected machine functions to remain energised briefly after the instantaneous safety outputs have switched off. This can be useful in applications requiring controlled stopping sequences before final isolation.
Operating from a 24 V DC supply, the SSR32P also provides selectable manual or automatic reset and uses push-in spring terminals for convenient control-panel wiring. Its compact 22.5 mm wide DIN-rail housing and IP20 construction make it suitable for installation inside industrial electrical cabinets where reliable safety monitoring and timed output control are required.
Key Advantages
- Safety relay combining instantaneous and delayed safety outputs.
- 2NO instantaneous + 2NO delayed relay outputs for flexible machine-safety control.

Reliable Safety Monitoring with Delayed Outputs
The ABB SENTRY SSR32P combines conventional safety-device monitoring with both instantaneous and time-delayed relay outputs. When the safety function is activated, the two instantaneous normally open outputs respond directly, while the two delayed normally open outputs remain active for a fixed 0.5 s before switching off.
This OFF-delay functionality can support machinery where certain actuators need to remain controlled briefly during a stopping sequence before final isolation. Combined with support for contact-based and OSSD safety devices, selectable manual or automatic reset and push-in spring terminals, the SSR32P provides a compact solution for machine builders requiring both safety monitoring and fixed delayed output control.
Typical Applications
- Emergency stop monitoring with delayed safety outputs.
- Safety gate and guard switch monitoring.
- Safety light curtains with compatible OSSD outputs.
- Controlled machine stopping sequences.
- Machinery requiring delayed isolation of selected actuators.
- Industrial production and assembly machinery.
- Packaging and material handling equipment.
- Conveyor and automated manufacturing systems.
- OEM machine building and industrial control panels.
