Solid state relays (SSRs) are semiconductor switching devices that provide galvanic isolation between control and load circuits, offering silent, fast, and maintenance-free operation compared to electromechanical relays. The Omron G3PJ series represents a family of single-phase SSRs designed for DIN rail mounting, featuring rated load currents from 18A to 27A and load voltage ranges of 24-240VAC or 100-480VAC. These relays incorporate a built-in heat sink and a display for operational status, with variants offering push-in (PU) spring-cage terminals for tool-less wiring. Control input is DC12-24V, making them compatible with standard PLC and industrial controller outputs. The series includes models like G3PJ-215B (18A, 24-240VAC), G3PJ-225B (27A, 24-240VAC), G3PJ-515B (23A, 100-480VAC), and G3PJ-525B (27A, 100-480VAC), each available with standard screw terminals or push-in connections.
These solid state relays are primarily deployed in industrial automation panels, temperature control cabinets, and process heating systems where precise and frequent switching of resistive loads is required. Typical applications include control of heating elements in plastic injection molding machines, packaging equipment, food processing ovens, and HVAC systems. They are also used in lighting control for high-bay and street lighting, as well as in motor soft-start circuits for small single-phase motors. The DIN rail form factor simplifies integration into existing control cabinets, while the built-in display aids in troubleshooting and status monitoring.
The Omron G3PJ series complies with international safety standards including UL, CSA, and CE markings, ensuring global acceptance. These SSRs are designed for compatibility with Omron PLCs and temperature controllers, but their standard DC control input makes them interoperable with any 12-24VDC sourcing output from brands like SiemensMitsubishi,. The push-in terminal variants (PU) are compatible with ferruled wires and standard cross-connection accessories, simplifying panel wiring and reducing installation time.
