Omron MY2 24VAC (S) Miniature Power Relay

The Omron MY2 24VAC (S) miniature power relay is a compact general-purpose relay designed for low-voltage AC control systems. It is part of Omron’s MY relay series, a popular choice in automation panels, HVAC systems, building control equipment, machine control circuits, and electrical cabinets. Its 24 VAC coil and DPDT contact configuration make it useful for applications where safe, reliable, and serviceable switching is required.

Technical Characteristics

This model operates with a 24 VAC coil. The DPDT contact arrangement provides two independent changeover contacts, allowing one relay coil to control two separate circuits. This is valuable in control logic, indication circuits, interlocking, signal transfer, and auxiliary switching tasks.

The plug-in terminal structure supports installation with a compatible relay socket. This type of mounting is especially useful in industrial and building control panels because it allows quick relay replacement without disturbing the field wiring.

Omron MY2 24VAC (S) Application Areas

The Omron MY2 24VAC (S) miniature power relay is commonly used in HVAC control circuits, building automation, low-voltage AC control panels, machine interfaces, and relay logic systems. The 24 VAC coil voltage is widely used because it provides a practical balance between control safety and system compatibility.

When used correctly, this relay helps separate control signals from switched loads, supports easier troubleshooting, and improves panel organization. For additional Omron relay references, visit Omron relay information.

Omron MY2 24VAC (S) FAQ

What is Omron MY2 24VAC (S)?

It is a miniature power relay with a 24 VAC coil, DPDT contact layout, and plug-in terminal construction.

Why is 24 VAC common in control systems?

24 VAC is widely used in HVAC, building control, and low-voltage control circuits because it is practical, standardized, and easier to manage than mains-level control voltage.

Can this relay be used in HVAC systems?

Yes, it is suitable for HVAC control circuits when the coil voltage, contact rating, socket, and load type match the system requirements.

What does the plug-in design offer?

The plug-in design allows faster replacement, cleaner wiring, and easier maintenance inside control panels.

How is it different from Omron MY2 24VDC (S)?

The main difference is the coil supply. This version uses 24 VAC, while the 24VDC model uses direct current control voltage.
