Your advantages

  • Large selection of switching devices for different safety functions
  • High product availability, thanks to proven safety technology
  • Fast installation and startup with user-friendly connection technology
  • Space saving, thanks to the slim design

Safe coupling relays for process technology

PSRclassic and PSRmini coupling relays  

SIL coupling relays for safe startup and safe shutdown

The coupling relays with force-guided contacts are SIL certified. They are used for electrical isolation and power amplification. Choose between the highly compact PSRmini version and the market-standard PSRclassic version. With widths of 6 and 12 mm, the PSRmini coupling relays are the narrowest coupling relays on the market. The product range features SIL coupling relays for safe startup (fire and gas) and for safe shutdown (emergency shutdown).

Safety relays for numerous safety functions

PSRclassic and PSRmini safety relays  

Safety relays for simple safety functions such as emergency stop and two-hand control

The safety relays reliably monitor the functional safety in your machine or system. When operating safety functions such as emergency stop, light grids, safety doors, or two-hand control, you can choose between the proven standard PSRclassic range and the highly compact PSRmini devices with an overall width of just 6 mm or 12 mm. Or, you can simply combine these product ranges to best suit your application.

Multifunctional safety relays with three functions in one device

PSRmultifunction multifunctional safety relays  

Multifunctional safety relays in three connection versions: screw, spring-cage, and Push-in

The multi-functional PSRmultifunction safety relays provide three safety functions such as emergency stop, safety door or light grid monitoring rolled into one device. Thanks to two local and one superordinate sensor circuit, the 22.5 mm-wide safety relays provide a narrow solution for many standard applications.

Zero-speed and over-speed safety relays reliably monitor rotating parts

PSRmotion zero-speed safety relays  

Highly compact zero-speed safety relays for drive monitoring without sensors

Use the narrow PSRmotion zero-speed safety relay to monitor the shutdown of a dangerous movement without additional sensors. For example, a guard locking device can be controlled in this way.

With the PSR-MM30 zero-speed and over-speed safety relays, you can monitor the speed of rotating parts in systems and machines. If a predefined speed is exceeded, the device shuts down safely.

Force-guided coupling relays for universal use

Force-guided coupling relays

The force-guided coupling relays are basic devices for single-channel control. You can use the coupling relays for electrical isolation, power amplification, and for increasing the number of contacts.

Like all PSR safety relay modules, the coupling relays are equipped with force-guided contacts according to EN 50205. This means you can use the coupling relays to perform reliable diagnostics via a force-guided N/C contact.
