Omron MY2-GS-R DC48 General Purpose Relay Technical Guide

The Omron MY2-GS-R DC48 general purpose relay is a plug-in electromechanical relay for control circuits using a 48 VDC coil. It features an 8-pin format, DPDT contact structure, and mechanical indicator. Omron Europe lists the product as a plug-in DPDT relay with a 48 VDC coil, while distributor data identifies socketable mounting, non-latching operation, silver contacts, and a 20 ms operate and release time. :contentReference[oaicite:4]{index=4}

Technical Overview

The MY2-GS-R DC48 is part of Omron’s MY series, a relay family used in industrial control panels, machine wiring, and electrical automation. The 48 VDC coil makes this model suitable for systems where 48 VDC is standard, such as certain power control environments, battery-supported equipment, telecommunications-related panels, UPS interfaces, and industrial auxiliary circuits.

Its DPDT contact configuration gives the relay two independent changeover contact sets. This is helpful when one control signal must switch two circuits or provide both normally open and normally closed logic paths.

Electrical and Mechanical Details

Distributor specifications list a 48 VDC coil, 18.8 mA coil current, 2.56 kOhm coil resistance, 38.4 VDC must-operate voltage, 4.8 VDC must-release voltage, and an operating temperature range of -55°C to 70°C. The relay is socketable and uses plug-in quick-connect style termination. :contentReference[oaicite:5]{index=5}

The mechanical indicator helps technicians verify relay actuation without immediately using a meter. This is valuable during preventive maintenance, startup checks, and troubleshooting of sequence circuits.

Best-Fit Applications

The Omron MY2-GS-R DC48 relay is well suited for DC control panels, backup power systems, industrial logic circuits, alarm panels, interface switching, equipment control, and auxiliary signaling. Its 48 VDC coil should be selected only when the control supply is designed for that voltage level.

Practical Selection Advice

Engineers should check contact ratings against the actual load, including inrush current and inductive behavior. If the relay is switching solenoids, contactors, motors, or coils, protective components may be needed to reduce electrical stress. The socket must also match the 8-pin relay layout and the panel’s wiring method.

For service teams, the plug-in structure is a major operational benefit. A relay can be replaced quickly, and the mechanical indicator provides a first-level diagnostic reference during live system checks when safety procedures allow inspection.

Omron MY2-GS-R DC48 FAQ

What coil voltage does the Omron MY2-GS-R DC48 use?

It uses a 48 VDC coil.

What does the relay’s DPDT contact form provide?

It provides two independent changeover contact sets that operate from one coil.

Is this relay designed for socket mounting?

Yes. It is a plug-in relay intended for compatible socket mounting.

Why would a 48 VDC relay be selected?

It is selected when the control system already uses 48 VDC, such as certain backup power, signaling, or industrial control environments.

What should be checked before replacing an older relay?

Confirm coil voltage, pin layout, contact configuration, contact rating, socket compatibility, and the load connected to each contact.
