Omron G2RV-1-SI-G 21VDC Ultra-Slim Industrial Socketed Relay: Technical Guide, Applications and Installation
Maintenance teams know the difference between components that merely survive and ones that genuinely perform over the long haul. The Omron G2RV-1-SI-G 21VDC Ultra-Slim Industrial Socketed Relay— 21V DC rated — falls firmly in the second category, making it a frequent first choice for PLC output modules environments.
Omron’s strength lies in offering complete automation subsystems rather than isolated components. The Omron Sensor lineup complements the relay and switch range by providing the detection layer, so the entire signal chain — from physical event to control output — stays within one trusted supplier.
Omron G2RV-1-SI-G 21VDC — Product Profile
The Omron G2RV-1-SI-G 21VDC is a Ultra-Slim Industrial Socketed Relay rated at 21V DC, built to handle PLC output modules reliably over a long service life. Key engineering features include only 6 mm wide, mosfet dc output, latch-connector plc interface, and the unit mounts via din rail.
On the bench, only 6 mm wide, mosfet dc output, latch-connector plc interface stands out immediately. The 21V DC rating align with the control voltage standards used across manufacturing, building automation, and process control industries, reducing the need for additional conversion stages.

Where This Product Fits
The Omron G2RV-1-SI-G 21VDC Ultra-Slim Industrial Socketed Relay is commonly specified for the following applications:
- Plc output modules
- Space-constrained panels
- Machine building
Across these use cases, the consistent thread is a need for dependable switching over a large number of operations, often in environments where an unplanned fault would create significant disruption. The Omron G2RV-1-SI-G 21VDC is designed with exactly those conditions in mind.
The Omron G2RV-1-SI-G 21VDC is designed to be used with G2RV socket terminal. Using a non-compatible socket model can compromise contact pressure and reduce overall service life, so always verify socket compatibility before ordering.
Practical Installation Tips
The Omron G2RV-1-SI-G 21VDC Ultra-Slim Industrial Socketed Relay follows standard DIN rail mounting practice. Before inserting the unit into its socket or fixing it to the rail, always verify the circuit is fully de-energised. Check that cable cross-sections are appropriate for the load, and after commissioning, mark the panel clearly with the device type and rated voltage for future maintenance reference.
For ongoing maintenance, periodically inspect for contact discolouration, check terminal screws for loosening, and look for any signs of heat stress on the housing. Catching these early avoids the much larger cost of an unplanned production stop.
Performance You Can Rely On
From a total cost of ownership perspective, the Omron G2RV-1-SI-G 21VDC Ultra-Slim Industrial Socketed Relay makes financial sense even when its purchase price is higher than alternatives. Reduced unplanned downtime, fewer replacement cycles, and lower maintenance labour costs add up to a clear advantage over the operational lifetime of a machine.
Frequently Asked Questions
What is the difference between the Omron G2RV-1-SI-G 21VDC and a mechanical contactor?
The Omron G2RV-1-SI-G 21VDC Ultra-Slim Industrial Socketed Relay is designed for panel-level signal and load switching at the current ratings specified. A contactor is built for direct motor starting at higher currents. For applications within the rated capacity of the Omron G2RV-1-SI-G 21VDC, it offers faster switching, longer life, and a smaller footprint than a contactor.
How does temperature affect the Omron G2RV-1-SI-G 21VDC?
Like all electromechanical devices, performance can be affected at the extremes of the operating temperature range. The Omron G2RV-1-SI-G 21VDC is rated for use across a defined ambient temperature range — consult the datasheet for precise limits and any derating requirements at elevated temperatures.
Can I mount multiple Omron G2RV-1-SI-G 21VDC units side by side on a DIN rail?
Yes. The Omron G2RV-1-SI-G 21VDC Ultra-Slim Industrial Socketed Relay is designed for standard DIN rail assembly with adjacent units. Ensure adequate total load current is within the rail and busbar capacity, and that enclosure ventilation is sufficient for the combined heat dissipation.
Does the Omron G2RV-1-SI-G 21VDC include a test facility?
Depending on the model variant, some Omron relay sockets include a manual test button or push-to-test function. Check the specific socket model specified for the Omron G2RV-1-SI-G 21VDC to confirm whether this feature is available.
How long is the warranty on the Omron G2RV-1-SI-G 21VDC?
Omron provides a standard 12-month manufacturer warranty on products purchased through authorised distributors. Extended warranty options may be available — contact your local Omron distributor for details.
