Omron MY2IN-GS 110/120VAC Power Relay: Technical Overview
The Omron MY2IN-GS 110/120VAC power relay is a plug-in general-purpose relay used in industrial control panels and automation circuits that operate with 110/120 VAC control voltage. It is part of the Omron MY relay series, known for compact construction, socket-based installation, visible status indication, and practical maintenance features.
This relay is typically selected when a control system needs dependable DPDT switching from an AC coil supply. It can be used in machine panels, HVAC control systems, pump panels, signal interface circuits, alarm circuits, and auxiliary control logic. The 8-pin plug-in structure allows fast installation and replacement when used with a compatible socket.
Technical Characteristics
The Omron MY2IN-GS 110/120VAC power relay is described as a plug-in relay with DPDT contacts, mechanical and LED indicators, a transparent housing, and a lockable push test button. Depending on the exact regional listing and series version, contact ratings may vary by load type and specification source, so the final design should always be checked against the official data sheet before installation.
The DPDT configuration provides two changeover contact sets. This allows one coil to switch two independent circuits, transfer signals between normally open and normally closed paths, or provide auxiliary feedback and control functions. The silver-based contact material supports stable electrical conductivity when applied within the relay’s specified load limits.
Why Visual Indication Matters
In real control panels, fast diagnosis is essential. The LED indicator helps technicians see whether coil voltage is present. The mechanical indicator confirms relay movement. Together, these features help separate electrical signal problems from mechanical contact or downstream wiring issues. The transparent relay case adds another layer of visibility, making inspection easier during maintenance.
The lockable push test button is useful during commissioning and troubleshooting. A technician can manually actuate the relay to confirm wiring, output response, and device behavior. This can reduce diagnostic time, especially in panels with many similar relays.
Typical Application Areas
The Omron MY2IN-GS 110/120VAC power relay is suitable for auxiliary switching in control cabinets, contactor control interfaces, machine status circuits, lighting control logic, HVAC panels, compressor controls, pump systems, and general automation panels. The AC coil rating makes it practical where 110/120 VAC control voltage is already available.
Correct socket selection is important for safe installation and long-term reliability. Engineers should also verify switching capacity, load type, ambient temperature, coil voltage tolerance, and applicable approvals before final use.

Omron MY2IN-GS 110/120VAC FAQ
What is the Omron MY2IN-GS 110/120VAC power relay?
It is a plug-in general-purpose relay with a 110/120 VAC coil, DPDT contact arrangement, visual indicators, and a push test button for panel applications.
Where is this relay commonly installed?
It is commonly installed in control panels, HVAC systems, machine automation cabinets, pump control panels, and auxiliary switching circuits.
What does the LED indicator show?
The LED indicator shows that the relay coil is energized, helping technicians quickly confirm whether the control signal is reaching the relay.
Why use a socket-mounted relay?
A socket-mounted relay simplifies installation, replacement, and maintenance. The wiring stays on the socket while the relay body can be replaced separately.
Can this relay switch inductive loads?
It may switch inductive loads within its specified limits, but inductive loads require careful rating checks and may need external suppression depending on the application.
