Daikin-McQuay 061019403 Relay

The Daikin-McQuay 061019403 Relay is a heavy-duty 24V SPDT Type 84 Relay engineered for precision switching in commercial and residential HVACR control circuits. As a Single Pole Double Throw (SPDT) component, this relay provides a versatile solution for managing normally open (NO) and normally closed (NC) contacts, making it essential for fan motor control, secondary heat sequencing, and low-voltage HVAC circuit management. Designed to meet OEM specifications, the 061019403 ensures seamless integration into existing Daikin McQuay air handlers and rooftop units.

For the technician in the field, this Type 84 relay features a compact footprint and standardized terminal layout for straightforward HVAC part replacement. It effectively replaces legacy part numbers including 0001420407, 02005291, and 026213000. Operating on a 24V control signal, the coil is optimized for minimal power draw while maintaining high inductive load switching capacity. This makes it a reliable choice for HVAC system diagnostics and repairs where robust electrical isolation between the thermostat and high-voltage components is required.

• Universal Compatibility: Direct replacement for multiple Daikin and McQuay SKUs, ensuring a proper fit for HVAC relay troubleshooting.
• SPDT Versatility: Features both NC and NO positions to handle diverse control circuit logic requirements.
• Rugged Type 84 Housing: Built specifically to withstand the high-cycle demands and thermal fluctuations found in air-side equipment.
• Reliable 24V Logic: Low-voltage coil design ensures safety and compatibility with standard HVAC control systems.

What does the SPDT configuration allow for?
The SPDT setup allows you to switch power between two different circuits using a single common terminal. This is vital when one component must shut off as another energizes, such as switching from a low-speed fan to a high-speed tap.

Can this relay replace a Type 84 relay from another brand?
While the 061019403 is a Daikin-McQuay part, its physical dimensions and electrical specs are standard for many Type 84 applications. Always verify that the 24V coil rating and contact amperage match your specific HVAC wiring diagram.
