Power/Signal Relay Omron G2RK-2-DC24, 2 poles, DC24V coil

The Omron G2RK-2-DC24 is a 2-pole power and signal relay with a 24 V DC coil designed for reliable switching of low- to moderate-current circuits in control panels, automation equipment and industrial devices. It offers galvanic isolation between the control input and load contacts, allowing safe on/off control of motors, indicator lights and signal lines in machinery and building systems. The relay’s compact form and standard pin layout make it suitable for panel mounting or socket installation in modular control systems.

Advantages

This relay combines dual-pole switching with a DC24V coil to provide independent switching of two circuits while maintaining electrical isolation. It supports both power and signal applications, reducing the need for separate relays for different circuit types. The device is designed for industrial environments and offers predictable switching behavior, a well-defined contact arrangement and compatibility with common sockets and panel layouts. Its construction enables straightforward replacement and integration into existing control architectures.

Suitable for

• Switching small motors, fans and actuators in automation systems
• Controlling indicator lights, alarms and signal lines
• Isolation and switching in building management and HVAC controls
• Use in control panels, relay sockets and modular automation racks

Key specifications

• Contact configuration: 2 poles (double-pole switching)
• Coil type and voltage: DC coil, 24 V
• Application: power and signal switching for low- to moderate-current circuits
• Isolation: galvanic separation between coil (control) and contacts (load)
• Mounting: suitable for panel mounting or standard relay sockets
• Typical industrial use: control panels, automation equipment, building systems

How to use

Install the relay into a compatible socket or secure it on the panel according to the manufacturer’s mechanical specifications. Connect the 24 V DC control supply to the coil terminals and wire the load circuits to the contact terminals, observing correct polarity for DC control circuits where applicable. Verify contact ratings against the expected load currents and use appropriate wiring, fuses and protective devices. Test switching operation at low load before placing the relay into full service to confirm correct wiring and function.

Usage recommendations

Ensure the coil voltage is a stable DC24V supply and do not exceed specified contact current ratings. Use protective components such as fuses, circuit breakers and suppression diodes or RC snubbers where inductive loads are switched. Maintain proper ventilation and ambient conditions within the relay’s specified environmental limits and replace the relay with an identical specification unit for consistent performance.
