Omron G7J Series Power Relay, 120V Coil Voltage, 25A Switching Current - G7J-4A-P 100/120VAC


This power relay is a Compact electromechanical switching device designed for PCB mounting in electrical and automation systems. It operates from an AC Coil and provides multiple single-throw contacts for controlling high-current circuits, enabling reliable switching in industrial control panels and equipment where board-level installation is required.

Features and Benefits:


• 120V AC Coil minimises external drive circuitry requirements
• Four independent normally-open contacts enable simultaneous circuit control
• 25A switching capacity supports high-current load handling
• 250V AC switching rating for robust alternating-voltage applications
• 125V DC switching rating suitable for direct-current circuits
• Silver alloy contact surfaces reduce contact wear and maintain low resistance

Applications


• Suitable for motor control circuits in industrial automation
• Ideal for power distribution switching on control PCBs
• Used for relay-based contactors in electrical panels
• Can be used for interfacing high-current loads in machinery
• Suitable for switching DC loads in battery-backed systems

What Coil power does it require and how does that affect drive design?


The Coil consumes 2.6VA, which informs the required driver capacity and heat budget for the PCB track design.

How should PCB mounting be planned for thermal and mechanical considerations?


The device is a PCB-mounted relay with a Compact footprint

allow clearance for airflow and ensure solder joints accommodate up to 60°C ambient operation.

What contact performance can be expected in terms of electrical resistance?


Contact resistance is specified at 100mΩ, indicating low voltage drop across closed contacts for heavy-current switching.

Which approvals are present to aid conformity assessments?


The unit holds recognised CSA and UL approvals, assisting certification reviews for safety-compliant installations.

Approvals

UL; CSA
