Omron MY2-GS-R DC100/110 General Purpose Relay Guide
The Omron MY2-GS-R DC100/110 general purpose relay is a plug-in, 8-pin, DPDT electromechanical relay designed for control panels, machine circuits, automation interfaces, and industrial switching tasks. It uses a 100/110 VDC coil and includes a mechanical indicator, making contact status easier to check during commissioning and maintenance. Omron lists this model as a MY series relay with DPDT contacts, plug-in mounting, and a 10 A class rating. :contentReference[oaicite:0]{index=0}
Technical Overview
This relay belongs to the Omron MY-GS-R family, a widely used miniature power relay range for dependable control circuit switching. The MY2-GS-R DC100/110 configuration provides two changeover contacts, also known as DPDT or 2 Form C. This makes it suitable for applications where one coil signal must control two separate circuits or switch between normally open and normally closed paths.
Its plug-in format allows quick replacement without rewiring the entire circuit. In control cabinet environments, this is a practical advantage because service teams can isolate the relay, remove it from the socket, and restore operation with less downtime. The mechanical indicator gives a simple visual confirmation of relay operation, which is useful when diagnosing sequence circuits or verifying panel behavior.
Where It Is Commonly Used
The Omron MY2-GS-R DC100/110 relay is often selected for DC control systems, industrial panels, automation equipment, interlock circuits, signal isolation, and auxiliary switching. Its 100/110 VDC coil rating makes it relevant for systems where higher DC control voltage is already available, especially in legacy panels or specialized industrial installations.
Because the relay uses silver alloy contacts and a general-purpose contact structure, it can handle many resistive and moderate inductive loads when applied within the manufacturer’s rating. Engineers should still verify load type, switching frequency, inrush current, ambient temperature, socket compatibility, and protection requirements before final selection.
Omron MY2-GS-R DC100/110 Key Engineering Considerations
When specifying this relay, the coil voltage should match the control supply. Using an incorrect coil voltage may lead to overheating, unreliable pickup, coil failure, or contact chatter. The DPDT arrangement should also be reviewed against the control logic. If the circuit requires two isolated switching paths from one coil signal, this relay is a strong fit.
For maintenance planning, the plug-in body and visible indicator make the component easier to inspect than a sealed board-mounted relay. In panel builds where repeatability and serviceability matter, that can reduce troubleshooting time.

Omron MY2-GS-R DC100 FAQ
What type of relay is the Omron MY2-GS-R DC100/110?
It is a plug-in general purpose electromechanical relay with an 8-pin base format, DPDT contact arrangement, and a 100/110 VDC coil.
What does DPDT mean on this relay?
DPDT means double pole double throw. The relay can switch two separate circuits, and each pole can move between normally closed and normally open contact paths.
Omron MY2-GS-R DC100/110 Why is the mechanical indicator important?
The mechanical indicator helps technicians see whether the relay has operated. This supports faster inspection during commissioning, maintenance, and troubleshooting.
Can this relay be used in automation panels?
Yes, it is commonly used in industrial automation panels for control logic, signal switching, interlocking, and auxiliary circuit control.
What should be checked before installation?
Check coil voltage, contact load, socket type, wiring diagram, ambient temperature, switching frequency, and whether surge suppression or external protection is required.
