Description
The IDEC Relays RR3B-UAC24V Power Relay 24 VAC is a plug-in electromechanical part used for switching control circuits in industrial automation units in HVAC systems. It operates with a 24 VAC coil. It allows control of multiple loads through a single piece of relay equipment. It is placed in control panels using a socket base, where it interfaces between low-voltage control signals and higher-load components such as fans, compressors, or auxiliary equipment. It is used for sequencing, interlocking, and signal switching processes during normal operation and maintenance.
