PSRuni multifunctional safety relays

PSRuni L and PSRuni S multifunctional safety relays

All safety functions in one device – compact, flexible, and efficient PSRuni multifunctional safety relays

With the PSRuni product family, Phoenix Contact offers a new generation of multifunctional safety relays that can monitor up to four safety functions in a single device. The solution combines maximum flexibility, intuitive operation, and very high safety standards for a wide range of industrial applications.

The PSRuni multifunctional safety relay enables the simultaneous monitoring of safety-related functions such as:

  • Emergency stop buttons
  • Light grids
  • Magnetic switches
  • Safety door locks
  • Type IIIA and IIIC two-hand controls
  • Four-wire switching strips or safety shut-off mats

This means that a single relay replaces several conventional modules and reduces wiring effort, space requirements, and costs.

Your advantages

  • Universal use by covering all common safety functions
  • Flexible adaptation to individual requirements
  • Space-saving and efficient monitoring of up to four safety functions in a single device
  • Fast startup with easy configuration
  • Can be used in applications up to the highest safety level, SIL 3/PL e

Individual configuration options Fast startup and easy maintenance

Configuration directly on the device via rotary coding switches
Software-based configuration via USB-C connection
Confirmation of the configuration settings directly on the device
Configuration directly on the device via rotary coding switches

PSRuni L enables fast and intuitive configuration directly (locally) on the device:

  • No PC
  • No additional software
  • All settings can be adjusted instantly via rotary coding switches

This approach saves time, reduces complexity, and enables quick adjustments to be made directly in the production environment.

Software-based configuration via USB-C connection

PSRuni S enables flexible, software-based configuration for advanced requirements:

  • Standardized USB-C interface
  • Free clipx ENGINEER Device Parameterization software

The PSRuni S offers a modular system for customized safety concepts: In addition to classic safety functions, it is also possible to flexibly define logic operations, start behavior, signal output behavior, delay types, and time parameters.

Confirmation of the configuration settings directly on the device

All configuration settings made are physically confirmed on the device.
