Omron MY2IN-D2-GS-R DC100/110 Power Relay: Technical Overview

The Omron MY2IN-D2-GS-R DC100/110 power relay is an industrial plug-in relay developed for control systems using 100/110 VDC coil voltage. It is part of Omron’s MY relay range and is used in control panels where a reliable DPDT switching device, visible operation status, and integrated coil protection are required.

This relay is specified as an 8-pin plug-in relay with DPDT contacts, 10 A rated carry current, silver contacts, LED indication, mechanical indication, transparent housing, diode coil surge absorption, and a lockable push test button. These characteristics make it suitable for industrial environments where diagnostics, serviceability, and dependable operation are important.

Technical Features

The 100/110 VDC coil rating makes this relay suitable for DC control architectures that operate above the common 24 VDC level. Such systems are often found in industrial control cabinets, utility equipment, process automation panels, and legacy machine control installations. The DPDT contact form allows two separate circuits to be controlled from one coil signal.

The built-in diode is one of the most important technical details of this relay. In DC coils, de-energization can generate a high reverse voltage. The diode provides coil surge absorption, reducing the voltage spike and supporting cleaner switching behavior. This helps protect control outputs and improves reliability in panels containing electronic devices.

Operational Visibility

The Omron MY2IN-D2-GS-R DC100/110 power relay includes both LED and mechanical indicators. The LED helps verify that voltage is being applied to the coil, while the mechanical indicator shows actual relay movement. In troubleshooting, this distinction matters because an energized coil does not always guarantee that the expected downstream circuit is functioning correctly.

The transparent case helps technicians visually inspect the relay without removing it from the socket. The lockable push test button is useful during commissioning, allowing manual actuation of contacts to confirm wiring, signal paths, and downstream device response.

Application Areas

This relay is suitable for DC control panels, auxiliary switching circuits, machine automation, signal interface circuits, alarm panels, pump control, utility equipment, and industrial sequencing systems. Its plug-in format supports efficient replacement and easier maintenance when paired with a compatible Omron socket.

Omron MY2IN-D2-GS-R DC100 FAQ

What is the Omron MY2IN-D2-GS-R DC100/110 power relay?

It is a plug-in industrial relay with a 100/110 VDC coil, DPDT contacts, diode surge absorption, visual indicators, and a lockable test button.

Omron MY2IN-D2-GS-R DC100/110 What does the R version add?

The R version is associated with the newer MY-GS-R style relay features, including practical panel-oriented improvements such as clear indication and test functionality.

Why is diode suppression important in DC relays?

Diode suppression reduces the reverse voltage generated when the coil turns off. This helps protect electronic control outputs and reduces electrical stress in the circuit.

Can this relay switch two circuits?

Yes. Its DPDT contact configuration provides two changeover contact sets, allowing two independent circuits to be switched by one coil.

Is the test button suitable for troubleshooting?

Yes. The lockable push test button helps technicians verify contact operation and downstream wiring during commissioning and maintenance.
