Supco 90380 General Purpose Fan Relay 13 A Load Current 24 V Coil Voltage Normally Open and Normally Closed Contacts

Supco 90380 General Purpose Fan Relay, 13 A Load Current, 24 V Coil Voltage, Normally Open and Normally Closed Contacts

Supco 90380 General Purpose Fan Relay, 13 A Load Current, 24 V Coil Voltage, Normally Open and Normally Closed Contacts - In other types of relay switches, non-moving parts such as transistors or semiconductors can be used as the control circuit to operate the switching mechanism. In a normally closed (nc) relay switch, when power is supplied to the relay, the load circuit is open and the power source connected to the relay is turned off. The supco 902 series fan relays receive and control electrical signals for general purpose fan applications. When current flows into the relay switch, it moves through the coil and a magnetic field is created, which causes the lever in the load circuit to move between contacts, either turning the device on or off. In a normally open (no) relay switch, when power is supplied to the relay, the load circuit is closed and the power source connected to the relay is turned on. This fan relay has spst-no, spst-nc, spdt-no/nc contacts made of silver alloy and coil voltage ratings of 24vac to 240vac. Relay switches can be controlled with an external switch, such as a light switch, or they can be connected to an automatically switched power source, such as a car ignition. It is suitable for use in fan applications. One relay can operate multiple switches, and multiple relays can be operated with a single switch, with each relay operating independently from the other relays in the system.

The company, founded in 1945, is headquartered in allenwood, nj. A basic relay switch has a control circuit with an electromagnetic coil and a load circuit with contacts and a lever. Supco manufactures test instruments and replacement parts for heating, ventilation, air conditioning, and refrigeration systems.
