General Purpose Relay is an electromechanical switch, usually operated by a magnetic coil. They operate with AC or DC current, at common voltages such as 12V, 24V, 48V, 120V and 230V, and they can control currents ranging from 2A-30A. These relays are economical, easy to replace and allow a wide range of switch configuration. They are applied mainly in industrial and power automation systems, in signaling and protection systems, and in other control and electric drive systems. It is also suitable for more common controlling applications like building automation or HVAC systems.
