Three safety functions in one device thanks to the multifunctional safety relay.
Safety functions such as emergency stop, safety door or light grid monitoring can be implemented easily with the PSRmultifunction device range – and all using a single device. In total there are four function versions available each with three connection methods.
The PSRmultifunction safety relays have three sensor circuits which can each be wired with single or dual channels:
The local sensor circuits S1 and S2 each provide a standard function such as a safety door or a light grid. When a fault occurs, both sensor circuits can be reactivated separately.
The higher-level sensor circuit S0 monitors both local sensor circuits. If it is triggered, the safety circuits protected by S1 and S2 are switched off.
