Omron MY2N-D2 24VDC (S) Miniature Power Relay
The Omron MY2N-D2 24VDC (S) miniature power relay is one of the most practical choices in the MY relay family for modern control panels. A 24 VDC control voltage is common in PLC cabinets, machine automation, process control, and industrial interface circuits, making this relay highly relevant for many electrical designs.
Omron identifies this model as a 2-pole plug-in miniature power relay with DPDT contacts, an LED operation indicator, silver contacts, and a built-in diode for coil surge absorption. The 24 VDC coil draws 36.3 mA and has a coil resistance of 662 ohms. Contact ratings include 220 VAC 5 A resistive, 220 VAC 2 A inductive, 24 VDC 5 A resistive, and 24 VDC 2 A inductive. :contentReference[oaicite:3]{index=3}

Industrial Value
The Omron MY2N-D2 24VDC (S) miniature power relay is often used as an interface relay between PLC outputs and field devices. It can help separate sensitive control electronics from load circuits while giving technicians a visible indication of coil status. This is valuable during commissioning, fault finding, and preventive maintenance.
The built-in diode reduces coil surge voltage, which is particularly important when the relay is controlled by semiconductor outputs. In many automation systems, this helps reduce electrical stress, improves switching stability, and supports cleaner panel wiring practices.

FAQ
Why is the 24 VDC version so common?
24 VDC is widely used in industrial automation because it is safe, standardized, and compatible with PLCs, sensors, solenoid control circuits, and interface modules.
Omron MY2N-D2 24VDC (S) What does the LED indicator do?
The LED shows when the coil is energized. This makes diagnostics faster because the relay state can be checked visually without measuring voltage immediately.
Does the built-in diode affect wiring?
Yes. Correct polarity is required. The positive and negative coil terminals must be wired properly for the relay and diode circuit to operate as intended.
Can this relay isolate a PLC output from a load?
Yes. It is commonly used as an interface relay, allowing a PLC output to control a separate load circuit through mechanical contacts.
Is the relay suitable for inductive loads?
Yes, within its inductive load rating. Inductive loads such as coils and solenoids require careful rating checks because they generate switching stress.
