Safety relay modules

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 an overall width of just 6 and 12 mm, the PSRmini coupling relays are the narrowest coupling relays on the market. The product portfolio features SIL coupling relays for safe switch-on (fire and gas) and for safe switch-off (emergency shutdown).

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 and 12 mm. Or, you can simply combine these product ranges to best suit your application.

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

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

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