Line capacities, 2-wire sensors, leakage current: WAGO’s socket with a miniature switching relay and a base load module provides safe and dependable operation at voltage levels below the release voltage for a wide variety of applications.

To ensure safe operation of a basic relay, voltage levels must remain above the response voltage and below the release voltage. Capacitive coupling, sensor power supply and leakage current are common factors that can wedge the voltage level between the base load and release voltages, which means that continued device functionality cannot be guaranteed.

The socket with miniature switching relay and integrated base load module (857-358/006-000) ensures that greater load is applied to the coupling to reduce voltage at the relay module input. This guarantees that the voltage level remains below the release voltage. A version of the socket with miniature switching relay and an integrated base load module that’s equipped with gold contacts (857-368/006-000) is also available.

Both of these new 857 Series components are just 6 mm wide and are DIN-rail mountable. Thanks to the uniform housing, all of the sockets can be jumpered at any clamping point. As with all other 857 Series components, the new sockets employ CAGE CLAMP®S connection technology that makes them easy to use and ensures reliability.
