The tailor-made safety system – optimally adapted to your safety functions.

With PSRmodular, you can retain functional safety in line with the modular system principle, meaning that you can assemble your safety system as required. In combination with the master safety relay and the DIN rail connector, this provides a flexible solution for the individual integration of functional safety.

 

Your advantages

  • Optimize safety devices, as only one master safety relay is required for various different functions
  • Quick and reliable startup, thanks to automatic operating mode detection
  • Can be individually adapted with extendable switch contacts
  • No time-consuming cross-wiring, thanks to PSR-TBUS DIN rail connector

 

Modular and flexible

The PSRmodular safety rail system is based on the master safety relay PSR-SDC4. With it you can reliably monitor emergency stop, safety doors or light grids. Up to ten additional safety relays can be connected to the master relay via the DIN rail connector. This eliminates the need for configuration, as the master relay detects all operating modes automatically.

You can therefore implement a safety system with a maximum of 42 contacts quickly and cost-effectively.

The time relays for functional safety have an adjustable dropout delay of 0.3 to 30 seconds.

 

Interface for functional safety

You can extend your PSR modular safety system as required. The PSR-SIM4 input module can be used to integrate eight additional inputs, e.g. for four safety doors, without any wiring or configuration effort.

 

Functional safety directly in the field

Do you need a robust input module in order to retrieve your safety signals directly in the field? Then the PSR-SACB sensor box is the ideal solution.

For example, you can connect four safety door switches, each with an N/C and N/O contact, to the compact modules with IP65/IP67 degree of protection.

LEDs clearly indicate the status of the connected contacts. Messages are sent via outputs Y1 to Y4.
