IDEC Relays RH4B-ULAC24V 4PDT General Purpose Power Relay 10A 24VAC

The IDEC Relays RH4B-ULAC24V General Purpose Power Relay is an electromechanical part that is used to switch several circuit at the same time in HVAC systems. It has a four-pole, double-throw design that enables four circuits to be independently controlled using one coil activation. The relay has a coil voltage of 24 VAC and can carry load currents to 10A, so it is useful in controlling fans, compressors, or auxiliary components. It is usually installed on control panels to provide isolation between control and power circuits, consistent switching performance, and help to coordinate and provide secure operation of heating, ventilation, and air conditioning components.
