Omron PCB Power Relay 24V DC Coil Voltage 25A Switching Current 3PST-NO SPST-NC G7J-3A1B-P 24VDC

Omron G7J-3A1B-P 24VDC PCB Power Relay is an industrial-grade switching device designed for PCB mounting, featuring a 24V DC coil voltage and capable of handling a switching current of 25A. It is ideal for applications requiring moderate to high current switching in both AC and DC circuits.

The relay offers three normally open poles and one normally closed pole (3PST-NO, SPST-NC), enabling multiplexed switching and combination control for multiple circuits with a single coil. Silver alloy contact material ensures low contact resistance of 100mΩ, maintaining high reliability and reduced electrical noise during operation.

This device can switch up to 250V AC and 125V DC, making it suitable for a variety of industrial electrical control systems. Its coil draws 2W power at 24V DC with a coil resistance of 288Ω, resulting in efficient coil current consumption. The PCB terminal design facilitates easy through-hole mounting on printed circuit boards, saving space while offering secure electrical connections.

With compact dimensions of 51.5mm length, 34.5mm width, and 51mm height, the relay fits well into constrained PCB layouts. It operates reliably across an ambient temperature range of -25°C to 60°C, suitable for typical industrial environments and non-climate controlled enclosures. UL and CSA approvals support its use in systems requiring recognized safety listings.

Common applications include motor starter controls within machinery panels, power distribution switching modules, industrial controller load isolation, and DC power switching in battery management systems. The robust design and certified standards make it a dependable choice for automation and control environments.
