The PSRtrisafe safety module is a configurable small-scale controller. It can be used for monitoring several safety functions in an application. The system functions as a standalone solution and can take over the entire machine control system in smaller machines. Or, you can extend the system modularly through the use of extension modules. Thus, the safety solution can be tailored precisely to your application. PSRtrisafe unifies functionality and flexibility, and fills the gap between simple safety relays and programmable safe controllers.

Your advantages

  • Several functions unified in one safety module
  • Easy configuration via drag and drop with the SAFECONF software
  • Safe operation, thanks to TÜV Rheinland-certified hardware and software
  • Flexible extension with additional safe I/O modules
  • Fast troubleshooting, thanks to comprehensive diagnostic options

Configurable safety module as a standalone solution

PSR-TRISAFE-S standalone version  

PSR-TRISAFE-S for standalone solutions

Monitor all of the safety functions within a system or machine with just one safety module.

The 20 safety-related inputs and four safe outputs of the PSR-TRISAFE-S safety module can be configured easily with just a click of the mouse using the SAFECONF software.

Safe extension modules for PSRtrisafe

PSRtrisafe – the extendable, configurable system  

Safe extension modules for an individual safety solution

Remain flexible by using the PSR-TRISAFE-M master module, and extend with additional digital extension modules. You can, for example, install additional relay outputs. The relay contacts are freely configurable and can be integrated easily into the safety logic. The SAFECONF configuration software is available free of charge for this. Thanks to the compact housing design of just 22.5 mm, they provide a great deal of functionality and flexibility in the smallest space and save space in the control cabinet.

Comprehensive diagnostics with LEDs and fieldbus couplers

PSRtrisafe with fieldbus coupler  

User-friendly remote diagnostics with the fieldbus coupler

Diagnostic LEDs indicate the states of all of the inputs and outputs of the PSRtrisafe safety module. In addition, signal outputs indicate the switching states, e.g., on signaling devices. The safety module communicates with the superordinate controller of your machine or system via the fieldbus coupler. This enables you to easily integrate your safety functions into visualization systems or remote diagnostics. Errors can be found and rectified more quickly.

Easy configuration with the SAFECONF software
