Omron G2R-1-DC24 24V DC SPDT Power Relay – 10A

The Omron G2R-1-DC24 Electromagnetic Power Relay is a compact, PCB-mounted relay designed for electrical switching, industrial automation, and electronic control applications.

Featuring a 24V DC coil, SPDT (Single Pole Double Throw) contact configuration, and 10A switching capacity, this relay provides reliable control of electrical loads through an electrically isolated switching circuit.

Its transparent housing allows visual inspection of the internal components, while its 5-pin through-hole design makes it suitable for PCB integration, electronic equipment, and industrial control systems.

Key Features

• 24V DC Coil: Designed for industrial and electronic control circuits.
• SPDT Contact Configuration: Single-pole changeover switching with NO and NC contacts.
• 10A Contact Rating: Suitable for switching compatible AC and DC loads.
• 5-Pin Design: Through-hole PCB mounting.
• Compact Construction: Suitable for space-constrained electronic assemblies.
• Transparent Housing: Allows visual inspection of internal components.
• Electrical Isolation: Separates the coil control circuit from the switched load.
• Industrial Applications: Suitable for automation, control panels, and electrical equipment.

Technical Specifications

Pin Configuration and Operation

The relay uses a 24V DC electromagnetic coil to control a single changeover contact.

Operating Principle

1. Apply the rated 24V DC supply to the relay coil.
2. The electromagnetic coil activates the internal switching mechanism.
3. The Normally Open (NO) contact closes.
4. The Normally Closed (NC) contact opens.
5. When the coil is de-energized, the contacts return to their original positions.

Arduino, ESP32 and PLC Compatibility

The relay can be controlled using a suitable driver circuit connected to an Arduino, ESP32, Raspberry Pi, PLC, or other controller.

For microcontroller applications:

• Use a regulated 24V DC supply for the relay coil.
• Use a transistor or MOSFET driver rated for the relay coil current.
• Include appropriate flyback protection across the coil.
• Connect the control circuit and relay coil supply with the required common reference.

Important: The relay coil must not be connected directly to a microcontroller GPIO pin.

Applications

• Industrial Automation Systems
• PLC Control Circuits
• Electrical Control Panels
• Power Supply Switching
• Home Automation Projects
• Motor Control Circuits
• Lighting Control Systems
• Electronic Equipment
• Embedded Control Systems
• PCB-Based Switching Applications

Important Notes

• The relay requires a 24V DC coil supply, not 24V AC.
• Verify the PCB footprint and pin arrangement before installation.
• Contact ratings depend on the load type and switching conditions.
• Inductive loads such as motors and solenoids may require additional contact protection.
• Do not exceed the specified switching voltage or current.
• Disconnect power before installation or maintenance.
• Mains-voltage applications require appropriate insulation, PCB clearances, and electrical safety precautions.
