Omron MY4IN-GS 100/110VDC Power Relay: Technical Guide, Applications and Installation
Picking the right component for a control panel takes more than scanning a catalogue. The Omron MY4IN-GS 100/110VDC is a Power Relay that has earned its place on the shortlist of engineers who value long service life over a bargain price — particularly in machine control panels applications.
In a well-designed automation system, the sensing layer and the switching layer work in close coordination. Omron’s Omron Sensor range is engineered to feed signals directly into relays and controllers from the same manufacturer, minimising compatibility concerns and simplifying system validation.
What Is the Omron MY4IN-GS 100/110VDC Power Relay?
The Omron MY4IN-GS 100/110VDC is a Power Relay rated at 100/110V DC, built to handle machine control panels reliably over a long service life. Key engineering features include gs din rail socket compatible, 4-pole switching, and the unit mounts via gs din rail socket.
What separates this unit from generic alternatives is in the details: gs din rail socket compatible, 4-pole switching. The coil operates at 100/110V DC, making it straightforward to match to existing control voltage buses without additional transformers or converters.

Where Is It Used?
The Omron MY4IN-GS 100/110VDC Power Relay is commonly specified for the following applications:
- Machine control panels
- Energy distribution systems
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 MY4IN-GS 100/110VDC is designed with exactly those conditions in mind.
The Omron MY4IN-GS 100/110VDC is designed to be used with GS series socket. Using a non-compatible socket model can compromise contact pressure and reduce overall service life, so always verify socket compatibility before ordering.
Installation Notes
The Omron MY4IN-GS 100/110VDC Power 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.
Why Choose the Omron MY4IN-GS 100/110VDC?
The case for choosing the Omron MY4IN-GS 100/110VDC Power Relay is not built on marketing alone. It rests on measurable factors: documented mechanical and electrical lifespan ratings, certifications that satisfy CE and UL requirements, and a global spare parts network that means you can source a replacement quickly when a unit eventually reaches end of life.
Frequently Asked Questions
What is the difference between the Omron MY4IN-GS 100/110VDC and a mechanical contactor?
The Omron MY4IN-GS 100/110VDC Power 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 MY4IN-GS 100/110VDC, it offers faster switching, longer life, and a smaller footprint than a contactor.
How does temperature affect the Omron MY4IN-GS 100/110VDC?
Like all electromechanical devices, performance can be affected at the extremes of the operating temperature range. The Omron MY4IN-GS 100/110VDC 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 MY4IN-GS 100/110VDC units side by side on a DIN rail?
Yes. The Omron MY4IN-GS 100/110VDC Power 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 MY4IN-GS 100/110VDC 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 MY4IN-GS 100/110VDC to confirm whether this feature is available.
How long is the warranty on the Omron MY4IN-GS 100/110VDC?
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.
