Omron G3PF Solid State Relay - Built-in Current Transformer
The Omron G3PF Solid State Relay is an advanced power switching solution designed for heater control applications requiring continuous current monitoring. This series represents a new-concept solid state relay that integrates a built-in current transformer, enabling reliable detection of heater burnout and SSR short-circuit failures. By combining load switching and current sensing in a single unit, the G3PF series simplifies panel design and reduces wiring complexity. This product is manufactured by Omron and is categorized under Omron Solid State Relay solutions for industrial heating and process control systems.
The Omron G3PF solid state relay is engineered to improve heater protection and system reliability in industrial automation environments. Its built-in current transformer (CT) allows direct load current monitoring without external sensors, helping reduce wiring steps and panel space. The G3PF series can detect the burnout of any single heater within a group, as well as identify failures in three-phase heater circuits, ensuring early fault recognition. In addition to heater monitoring, it also detects SSR short-circuit failures, preventing uncontrolled heating and potential equipment damage. Error detection levels can be easily adjusted using a front-mounted switch, enabling flexible setup for different load conditions. The relay supports DIN track mounting or screw mounting and offers multiple input terminal options, including M3 screw terminals, screwless clamp terminals, and compact slotted screw terminals. This makes the G3PF series a reliable and space-efficient solid state relay solution for industrial heating, plastics processing, and temperature control panels.
