Phoenix Contact 2966540 Interface Relay

The interface relay, also known as coupling relay, signal converter, or isolation relay, with type number 2966540 from Phoenix Contact is an electrical relay for interface tasks for electrical isolation and signal conversion between control and actuation. It has the dimensions 10 x 1 x 10 cm and weighs 0.03 kg. Another part number for this product is L0861653 from Koenig & Bauer (KBA). Interface relays are used for reliable signal transmission between different voltage levels or circuits. They decouple control circuits from load circuits, protect sensitive electronics from interference, and enable the adaptation of signal levels. Typical applications can be found in automation technology, mechanical engineering, process control, and building automation for protecting PLC outputs and controlling valves or motors.
