Omron MY2IN-GS-R AC12 Miniature Power Relay Guide

The Omron MY2IN-GS-R AC12 miniature power relay is a compact plug-in relay built for 12 VAC control circuits. It is part of the MY-GS-R range and is commonly specified with an 8-pin plug-in body, DPDT contact arrangement, 10 A rated carry current, mechanical indicator, LED indicator, transparent case, and lockable push-test button.

Product Overview

This relay is suitable for engineers and technicians who need a serviceable relay for industrial panels, machine controls, and automation interfaces. The 12 VAC coil makes it appropriate for systems where low-voltage AC control power is available. Its DPDT structure gives two independent changeover contact sets, allowing one coil signal to operate two separate circuits.

The MY2IN-GS-R AC12 is designed for socket mounting. This makes installation cleaner and service work faster. If a relay needs replacement, the wired socket can remain in place while the relay body is removed and replaced.

Key Technical Features

Official product references describe the Omron MY2IN-GS-R AC12 as a relay with plug-in mounting, 2 poles, 10 A rated carry current, 12 V AC coil voltage, silver contacts, DPDT contact description, LED indication, test button, transparent case, mechanical indicator, and plug-in or solder terminal compatibility depending on the socket arrangement.

The lockable push-test button is especially useful during commissioning. It allows a technician to manually operate the relay for testing, while the lockable function can support controlled diagnostic procedures. The transparent cover and mechanical indicator make the relay easier to inspect without removing it from the panel.

Typical Applications

The relay can be used in control panels, signal interface circuits, small motor control, lighting circuits, heater control, alarm circuits, and machine automation. The 10 A rated carry current makes it suitable for many general-purpose control applications, provided the connected load matches the approved contact rating.

Socket Compatibility

The MY-GS-R range is commonly associated with compatible Omron socket families such as PY08 and PYF 8-pin socket options. Socket choice affects wiring style, panel layout, and service access. Push-in terminal sockets may reduce wiring time, while screw terminal sockets may be preferred in traditional panel builds.

Practical Selection Advice

When selecting the relay, confirm that the control supply is 12 VAC, not 12 VDC. Also review the load voltage, load current, contact type, ambient conditions, and expected switching frequency. For inductive loads, protective measures may be needed to reduce electrical stress on the contacts.

FAQ

What is the Omron MY2IN-GS-R AC12?

It is a miniature plug-in power relay with a 12 VAC coil, DPDT contact configuration, mechanical and LED indicators, and a lockable push-test button.

What is the rated carry current?

The MY2IN-GS-R AC12 is commonly specified with a 10 A rated carry current. The final load suitability depends on voltage, load type, and application conditions.

What does the lockable test button do?

It allows manual relay operation during testing and troubleshooting. This helps verify connected circuits without relying only on the automatic control signal.

Can this relay be used in automation panels?

Yes. It is well suited for control panels, PLC interface circuits, machine control wiring, indicator circuits, and auxiliary switching tasks.

Omron MY2IN-GS-R AC12 Is the AC12 model the same as the DC12 model?

No. The AC12 version uses a 12 VAC coil, while the DC12 version uses a 12 VDC coil. They must not be interchanged unless the control circuit is designed for that coil type.

Why is the transparent case useful?

The transparent case allows technicians to visually inspect the relay mechanism and confirm operation status without removing the relay from its socket.
