Omron MY2IN-GS-R DC12 Miniature Power Relay Guide
The Omron MY2IN-GS-R DC12 miniature power relay is a 12 VDC plug-in relay designed for general-purpose industrial control applications. It is commonly specified with an 8-pin format, DPDT contact arrangement, 10 A rated carry current, LED indicator, mechanical indicator, transparent case, and lockable push-test button.
Product Overview
This relay is used when a 12 VDC control signal must switch one or two external circuits through mechanical contacts. The DPDT contact configuration provides two changeover contact sets, making the relay flexible for control logic, signal routing, interlocking, alarm outputs, and auxiliary switching.
The Omron MY2IN-GS-R DC12 is especially useful in panels that rely on direct-current control power. Many automation systems use DC control circuits because they integrate well with PLC outputs, sensors, interface modules, and low-voltage control electronics.
Key Technical Features
Official references describe the MY2IN-GS-R DC12 with plug-in socket mounting, general-purpose use, 2 poles, 10 A rated carry current, 12 V DC coil voltage, silver contacts, DPDT contact description, LED indication, test button, transparent case, mechanical indicator, and plug-in or solder terminal compatibility through appropriate socket selection.
The built-in LED indicator helps technicians see coil energization at a glance. The mechanical indicator confirms physical contact movement, while the transparent case supports visual inspection. The lockable push-test button is helpful during commissioning because it allows manual relay operation for controlled circuit checks.
How the Relay Works
When 12 VDC is applied to the coil, the internal magnetic field moves the relay armature. This changes the contact state. Normally open contacts close, and normally closed contacts open. When power is removed from the coil, the relay returns to its rest position.
Common Applications
The MY2IN-GS-R DC12 can be used in PLC interface circuits, control panels, alarm systems, signal isolation, machine control, auxiliary load switching, test benches, and service-friendly automation assemblies. Its socket-based construction makes it easy to replace during maintenance without rewiring the entire circuit.
Installation and Design Notes
The control circuit must provide the correct 12 VDC coil voltage. Contact load should be reviewed carefully, especially for inductive devices such as solenoids, contactor coils, valves, and motors. Inductive loads may require suppression to reduce arcing and extend relay life. A compatible 8-pin socket should be selected based on panel wiring style and service requirements.

Omron MY2IN-GS-R DC12 FAQ
What is the Omron MY2IN-GS-R DC12?
It is a 12 VDC miniature plug-in power relay with DPDT contacts, LED and mechanical indicators, and a lockable push-test button.
What is the current rating of this relay?
The MY2IN-GS-R DC12 is commonly specified with a 10 A rated carry current. The actual switching suitability depends on load voltage, load type, and operating conditions.
Can it be used with PLC outputs?
Yes, it can be used when the PLC output is compatible with the 12 VDC coil requirements. It can provide isolation and contact-based switching for external circuits.
What is the benefit of the DPDT contact arrangement?
DPDT contacts allow two separate circuits to be switched by one coil signal. This is useful for combined signaling, interlocking, or dual-circuit control.
Is this relay interchangeable with the AC12 model?
No. The DC12 model requires a 12 VDC coil supply, while the AC12 model requires 12 VAC. The correct coil type must be used for reliable and safe operation.
Omron MY2IN-GS-R DC12 Why is the push-test button important?
The push-test button allows manual operation during inspection, commissioning, or troubleshooting. It helps technicians confirm wiring and load response before automatic operation.
