This Omron G7L-2A-BUBJ-CB AC100/120 general purpose relay has a test button, Class B rated insulation material, screw terminal connections, upper bracket mounting, and is suitable for use in high capacity voltage applications. This relay has double pole single throw normally open (DPST-NO) contacts, an input current rating of 17 to 20.4 mA and a load rating of 220VAC at 25 amp, with an input of 100 to 120VAC. This relay has a test button for checking the status of operation and Underwriter's Laboratories (UL) Class B rated insulation material for flame resistance. This general purpose relay is designed to mount to an upper bracket in an equipment rack and is suitable for high capacity voltage applications such as fluid pump controls in the water and chemical processing industries.

Relay switches (also called an electrical relay or an electrical relay switch) use a small amount of power to control a larger source of power connected to electrical devices such as car motors, computers, and lighting installations. A basic relay switch has a control circuit with an electromagnetic coil and a load circuit with contacts and a lever. 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. 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. 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. 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. 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.
Omron manufactures and distributes electronic components, equipment, and systems for industrial automation. The company, founded in 1933, is headquartered in Kyoto, Japan.
