Preventa Safety Relays (XPS)

A safety relay is the simplest way to build a certified safety function: the module monitors the e-stop or guard circuit on two independent channels, checks itself on every cycle and only allows the machine to start when both channels agree and the reset is deliberate. The 22.5 mm housings mount on standard DIN rail with plug-in terminals, and the front LEDs show exactly which channel is holding the machine off — which is what shortens fault-finding at three in the morning.
