ADAM-3854 4-ch Power Relay Module

ADAM-3854 4-ch Power Relay Module (ADAM-3854)

The ADAM-3854 features four industrial SPDT (Form C) electromechanical power relays and a DIN-rail mount. Each of the relays is controlled by a +24 VDC digital signal and is equipped with an adjacent LED to display its status. Each output is equipped with a varistor that shunts the surge voltage of an inductive load or electromagnetic brake to protect the relay contact points. All the relay outputs and relay controls are accessible through wiring terminals, allowing the ADAM-3854 to be easily connected to any item of equipment or device such as programmable logic controllers (PLCs).
