Schneider Electric Plug In Power Relay, 48V dc Coil, 3A Switching Current, 4PDT

Introducing Schneider Electrics compact RXM miniature relays with LED. They are often used to increase the functions in electrical enclosures, predominantly for industrial applications (machine/building equipment and HVAC). These relays can be referred to as an electromechanical relay or an industrial switch.

A relay is an electrical switch that is operated by electrical pulses, their primary function is to open and close a circuit. When power passes through a circuit, a relay switches position (usually from NC to NO) using an internal coil which generates a magnetic force. This force then holds the relay in a NO position, when the current is switched off the relay returns to the NC position. This function is what makes these non-latching relays perfect for push-button applications such as keyboards and micro-controller input buttons.
