This Omron G3PE-225B DC12-24 solid state relay for heater control has a zero cross function, a built-in yellow operation indicator, phototriac coupler isolation, a single-phase output, and screw mounting. It has a load voltage rating of 100 to 240 VAC, a load current rating of 25 amp, and an input of 12 to 24 VDC. This relay has screw terminals for connecting to contacts and zero cross functionality to reduce noise generated when the load current rises suddenly. The phototriac coupler 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 and a heat sink, an attached component that cools the relay by passively dissipating heat into the surrounding air. This solid state relay mounts to a panel with screws and is suitable for use with heaters, industrial controls and commercial cooking applications.

*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.
