Omron MY2 220/240VAC (S) Miniature Power Relay

The Omron MY2 220/240VAC (S) miniature power relay is a compact plug-in relay designed for control circuits that operate with mains-level AC control voltage. As part of Omron’s MY relay family, it is widely used in industrial cabinets, machine control systems, auxiliary switching circuits, and electrical control panels where reliable two-pole switching is required.

Technical Characteristics

This relay is designed for 220/240 VAC coil operation, making it suitable for systems where high-voltage AC control power is already available. Its DPDT contact configuration provides two independent changeover contacts, allowing the relay to control two separate circuits from one coil input.

The plug-in design allows the relay to be installed in a compatible socket. This supports organized wiring, easy replacement, and reduced downtime during maintenance. The enclosed relay body protects the internal mechanism while maintaining a compact footprint for dense panel layouts.

Electrical Role in Control Panels

The Omron MY2 220/240VAC (S) miniature power relay is often used in auxiliary control, interlock logic, signal routing, indicator circuits, and switching functions inside industrial control systems. It is especially practical when the control architecture is based on 220 or 240 VAC.

Although it can switch both AC and DC loads within its specified limits, load type must always be reviewed carefully. Inductive loads, such as coils and solenoids, require more attention than resistive loads because they can generate electrical surges during switching.

FAQ

What is Omron MY2 220/240VAC (S)?

It is a miniature plug-in power relay with a 220/240 VAC coil and DPDT contacts for general-purpose switching.

When should this voltage version be selected?

It is selected when the control system already uses 220 or 240 VAC as the relay coil supply voltage.

Is this relay suitable for control cabinets?

Yes, it is commonly used in control cabinets because of its compact size, socket mounting, and standard relay format.

Can it switch DC circuits?

Yes, it can switch DC circuits if the load remains within the relay’s approved contact rating.

Is it intended for heavy motor switching?

No, it is primarily intended for control and auxiliary switching. Motor loads should be handled only after checking suitable ratings and protection requirements.
