Omron MY2-AC24 Relay
Experienced HVACR contractors and industrial technicians rely on the Omron MY2-AC24 relay for precise control circuit management. This 24VAC DPDT plug-in relay features a dual-pole, double-throw contact configuration, making it a versatile component for managing multiple loads or interlocking circuits in HVAC control panels, automation systems, and motor starters. Designed with Miniature Power Relay architecture, it handles up to 10A switching current for resistive loads (at 250VAC/30VDC) and is built with high-conductivity silver alloy contacts to minimize voltage drop and heat generation.
The Omron MY2-AC24 is a standard-setting replacement part in the MY Series, known for its durable transparent dust cover and 8-pin blade terminal layout. It integrates seamlessly with PYF08A sockets or PYFZ-08-E bases, allowing for rapid field replacement without re-wiring. With a mechanical endurance rating of 50 million operations and an electrical switching capacity of 500,000 cycles, this industrial control relay provides the long-term reliability required in critical 24V secondary control loops. Its 180-ohm coil resistance and low power consumption (approximately 1.2 VA) ensure compatibility with standard 24V class 2 transformers commonly found in commercial furnace and air handler setups.
Key Benefits for Technicians
- High Switching Capacity: Handles up to 10A resistive loads, making it suitable for larger solenoids and contactor coils.
- Universal Compatibility: Fits standard 8-pin relay sockets (PYF series), simplifying inventory for service vans.
- DPDT Contact Form: Allows for simultaneous switching of independent circuits, essential for pilot duty and signal logic.
- Robust Environmental Tolerance: Operates efficiently in temperatures ranging from -55°C to 70°C, ideal for rooftop units and mechanical rooms.
- Fast Operation: Features a 20ms maximum operate/release time for responsive system sequencing and protection.
Common Technical Questions
Can the MY2-AC24 handle 10A on inductive loads?
No, while the carry current is rated at 10A, the maximum inductive switching capacity (cosφ = 0.4) is typically rated at 2A at 220VAC. For high-amp inductive motor loads, ensure you are utilizing the relay within its technical ratings or as a pilot device for a larger contactor.
Will this relay work with a DC control circuit?
No, this specific model is built with a 24V AC coil (50/60 Hz). Applying DC voltage to an AC coil will lead to improper operation or coil burnout. Always verify your coil voltage against the "24 VAC" marking on the relay housing.
Is there a visual indicator for operation?
The standard MY2 series features a transparent case for visual inspection of the armature and contacts. If your application requires an LED indicator or test button, ensure you are specifying the "N" (indicator) or "I" (test button) variants, as the base MY2 model is the standard non-illuminated version.
