Omron G3PF-225B Solid-state Relay
Omron G3PF-225B is a single-phase, 2-element solid state relay with phototriac isolation and a 12 to 24 VDC rated input. The input operates across 9.6 to 26.4 VDC, while its rated output voltage is 100 to 240 VAC with a 75 to 264 VAC load voltage range. Output load current is specified as 25 A at 25°C and output inrush current resistivity is 220 A for one 60 Hz cycle. The model supports DIN track or screw mounting and uses detachable screwless clamp terminals, a yellow operating indicator, and an equipped zero-cross function. The G3PF-225B belongs to the G3PF series within the Solid state relay lineup from Omron.

The Omron G3PF-225B Solid State Relay uses a single-phase, 2-element configuration with phototriac isolation and detachable screwless clamp terminals. It supports DIN track or screw mounting and includes an equipped zero-cross function plus a yellow operating indicator. Rated input voltage is 12 to 24 VDC and the specified operating range is 9.6 to 26.4 VDC. Input current is 5 mA max. at 12 VDC and 10 mA max. at 24 VDC, while input operate voltage is 9.6 VDC max. and release voltage is 1 VDC min. The output side is rated for 100 to 240 VAC across a 75 to 264 VAC load voltage range. Output load current is 25 A at 25°C, and output inrush current resistivity is 220 A for one 60 Hz cycle.
Operate time and release time are each one-half cycle of the load power source plus 1 ms max. Main-circuit output ON voltage drop is 1.6 V max. RMS and main-circuit leakage current is 10 mA max. at 200 VAC. Insulation resistance is 100 MΩ min. at 500 VDC, with dielectric strength of 2500 VAC at 50/60 Hz for 1 minute. Ambient operation ranges from -30 to 80°C without freezing or condensation. The related CTB version retains the same principal input, output, current, and inrush values: G3PF-225B-CTB.
