Reznor 263527 Relay

The Reznor 263527 Relay is a specialized OEM component designed for high-reliability switching in Reznor HVAC systems. Featuring a Single Pole Double Throw (SPDT) configuration, this relay operates on a 24VAC control circuit to manage critical system loads, including blower motor activation, venter motor sequences, and ignition control circuits. As a critical replacement part, the 263527 serves as the direct successor to the Reznor 14747 and Reznor 103317, providing seamless mechanical and electrical compatibility with legacy unit heaters.

Engineered to withstand the high-temperature environments of commercial gas-fired unit heaters, this 24V HVAC relay features robust contacts rated for 12FLA at 125VAC and 8FLA at 250VAC. Whether you are performing a Reznor unit heater repair or upgrading a power venter relay, the 263527 ensures precise electrical isolation and switching performance. Its compact, universal mounting design allows for rapid field installation, reducing downtime during emergency service calls. This Reznor replacement relay is essential for maintaining the sequence of operation in infrared heaters and standard forced-air systems.

• Direct OEM Replacement: Replaces Reznor 14747 and 103317 without the need for additional wiring modifications or mounting adjustments.
• Versatile SPDT Configuration: Provides flexible switching for both normally-open and normally-closed terminal paths, ideal for single-stage heating and exhaust ventilation.
• Industrial-Grade Ratings: Designed for 50/60Hz frequency operation with contact capacities suitable for high-amperage HVAC blower motors.
• High Dielectric Strength: Built to handle the rigorous switching cycles of commercial heating equipment, ensuring stable performance across the 24V coil.

Can I use this relay to replace an old RBM 134-20103-301?
Yes, the 263527 is the verified manufacturer replacement for that specific RBM ignition relay and its predecessors like the 14747.

What is the primary function of this relay in a Reznor unit heater?
It typically functions as the power venter relay or fan relay, receiving a signal from the thermostat or control board to close the circuit for the motor.

Is this compatible with 120V or 240V coils?
No, this unit is built with a 24VAC coil specifically for low-voltage control circuits. Using higher voltages on the coil will result in immediate part failure.
