  • UL listed for safety and CSA certified for quality assurance

Product Description

This Omron G3NA-240B AC100-120 solid state relay has a zero cross function, a built in yellow operation indicator, photocoupler isolation, and is suitable for high-speed switching in low current applications. It has a load rating of 24 to 240VAC at 40 amp, with an input of 100 to 120VAC. This relay has screw terminals for connecting to contacts and zero cross functionality to reduce noise generated when the load current rises suddenly. The photocoupler component isolates the input and output signals by transferring the input signal using light, preventing high voltages from affecting the signal. It has a built-in yellow operation indicator to alert users to the operation status of the relay. This solid state relay is suitable for use with industrial controls and commercial cooking applications.

Input Voltage100 to 120VAC
Load Rating24 to 240VAC, 40 amp
Operating Temperature-30 to +80 degrees C
Enclosure Dimensions*27 x 43 x 58mm (H x W x D)
Standards MetUL (Underwriter's Laboratories)
CSA (Canadian Standards Association)

*H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

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.
