G3PE-225B

Overview of Omron G3PE-225B

The Omron G3PE-225B is a single-phase solid state relay (SSR) designed for switching AC loads with rated voltages from 100 to 240 VAC, up to 25 A at 40°C ambient temperature. It operates on a 12 to 24 VDC input control voltage with a maximum current of 15 mA and features built-in zero-cross detection for reduced electrical noise and minimized load stress. The relay is housed in a compact DIN rail mountable case with built-in heat sinks, making it suitable for control of heaters and motors in industrial automation.

Key Features of Omron G3PE-225B

• Input Control Voltage: 12 to 24 VDC with a maximum input current of 15 mA.
• Output Load Voltage: 100 to 240 VAC with a rated load current of 25 A at 40°C ambient temperature.
• Zero-Cross Function: Built-in zero-cross switching to minimize surge current and reduce electrical noise.
• Operate and Release Times: Operate time within 1 ms max after zero-cross; release time up to half load power source cycle plus 1 ms.
