Safe coupling relays – each signal is reliably available

PSRclassic and PSRmini coupling relays  

Coupling relays for safe startup and shutdown

The classic safe coupling relays with force-guided contacts are SIL-certified and are used for electrical isolation and power amplification.

When it comes to the PSR coupling relays, there is a choice between the PSRclassic, the standard version on the market, and the entirely new PSRmini. At 6 and 12 mm, these new coupling relays are the narrowest on the market.

Safety relays – the ideal solution for every function

PSRclassic and PSRmini safety relays  

Safety relays for simple functions such as emergency switching off and two-hand control

In the safety relay field, two device series are available: the PSRmini and PSRclassic. When operating basic functions such as emergency switching off or two-hand control, you can choose between the proven standard range, PSRclassic, or the new, extremely compact PSRmini devices measuring just 6 mm and 12 mm. Or combine these to best suit your application.

Multifunctional safety relays – three functions in one device

PSRmultifunction multifunctional safety relays  

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

The multifunctional PSRmultifunction safety relays implement three safety functions such as emergency switching off, safety door or light grid monitoring in one device. Thanks to two local and one higher-level sensor circuit, they provide a slim solution for many standard applications.

Zero-speed and over-speed safety relays – safely 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 downtime of a dangerous movement without additional sensors. For example, a guard locking device can be controlled in this way. Downtime is detected by evaluating the voltage induced in the motor winding.

The PSR-RSM4 zero-speed and over-speed safety relays monitor the speed of rotating parts in systems or machines. If a predefined speed is exceeded, for example, the device shuts down safely.

Force-guided coupling relays – for universal use

Force-guided coupling relays for universal use  

Force-guided coupling relays

The force-guided coupling relays are basic devices for single-channel control. They can be used for electrical isolation, power amplification, and 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.
