Omron MY2N-D2 100/110VDC (S) Miniature Power Relay

The Omron MY2N-D2 100/110VDC (S) miniature power relay is a DC-operated plug-in relay built for industrial control circuits that require reliable switching, visual status indication, and coil surge suppression. It belongs to Omron’s MY relay family, a widely used series for control panels, sequence control, and general-purpose switching.

This model uses a 100/110 VDC coil and includes a built-in diode for coil surge absorption. Omron lists the coil current as 8.7 mA at 100 VDC and 9.6 mA at 110 VDC, with a coil resistance of 11,440 ohms. The relay has DPDT contacts, silver contact material, plug-in terminals, and an LED operation indicator. :contentReference[oaicite:1]{index=1}

Technical Overview

The D2 configuration is important because the built-in diode protects surrounding control electronics from reverse voltage generated when the relay coil is de-energized. In DC relay circuits, this feature can be valuable for PLC outputs, transistor drivers, and other sensitive electronic switching devices.

Omron MY2N-D2 100/110VDC (S) Where This Relay Fits Best

The Omron MY2N-D2 100/110VDC (S) miniature power relay is well suited for DC control systems, utility panels, industrial automation cabinets, and applications where higher DC control voltage is used. Because the relay is socket-mounted, field replacement is straightforward, reducing downtime during maintenance.

The relay’s DPDT contact arrangement allows it to switch two circuits simultaneously. This makes it useful in control logic, alarm circuits, interlock systems, status indication, and isolation between low-current control signals and higher-power loads.

Omron MY2N-D2 100/110VDC (S) FAQ

What is the Omron MY2N-D2 100/110VDC (S) designed for?

It is designed for DC control panels and automation circuits where a 100/110 VDC relay coil is required.

What does D2 mean in this relay model?

D2 refers to the built-in diode used for coil surge absorption. This helps protect electronic outputs from voltage spikes generated by the coil.

Is polarity important when wiring this relay?

Yes. Because this is a DC relay with a built-in diode, correct polarity is important. Reversed polarity may prevent proper operation or damage the circuit.

Does the relay include an operation indicator?

Yes. It has an LED indicator, allowing technicians to visually confirm whether the coil is energized.

Can this relay be used for resistive and inductive loads?

Yes, but the load must stay within the published ratings. Resistive loads allow higher current than inductive loads because inductive circuits create additional stress during switching.
