G3PF
Solid-state relays (SSRs) are semiconductor switching devices that provide galvanic isolation between control and load circuits, offering silent, arc-free, and high-speed switching for resistive and inductive loads. The Omron G3PF series includes single-phase SSRs rated from 25A to 35A, with operating voltages of 100-240VAC or 200-480VAC, contro...
Solid-state relays (SSRs) are semiconductor switching devices that provide galvanic isolation between control and load circuits, offering silent, arc-free, and high-speed switching for resistive and inductive loads. The Omron G3PF series includes single-phase SSRs rated from 25A to 35A, with operating voltages of 100-240VAC or 200-480VAC, controlled by a 24VDC input. These relays feature built-in current transformers for load monitoring, and are available with screw terminals, cage clamp terminals, or fast-connection terminals. Models with two outputs (STB or CTB suffixes) include dual alarm outputs for overcurrent or heater burnout detection, making them ideal for precision thermal control in industrial processes.
These SSRs are primarily used in industrial heating applications, such as plastic injection molding machines, packaging equipment, drying ovens, and HVAC systems. They are designed for panel mounting in control cabinets, where they replace electromechanical contactors in high-cycling environments. The built-in current transformer allows real-time monitoring of heater current, enabling predictive maintenance and reducing downtime in continuous production lines. They are also suitable for lighting control, motor soft-start, and any application requiring frequent switching without mechanical wear.
The G3PF series complies with international standards including UL, CSA, and CE, ensuring safety and reliability in global installations. They are compatible with Omron's PLCs and temperature controllers, as well as other major automation brands like Siemensand Mitsubishi. The 24VDC control input is standard across industrial control systems, allowing direct connection to digital outputs of PLCs or distributed I/O modules. The series offers IP20 protection for the housing, suitable for clean, dry environments.
