Bard HVAC 8201-045BX Relay

The Bard HVAC 8201-045BX Relay is a specialized SPDT time delay relay engineered for precise sequencing in commercial and industrial HVACR systems. As a direct replacement for 8201-045, this Bard OEM part ensures seamless field integration without the need for mounting modifications or terminal re-wiring. Designed for the high-duty cycles found in Bard wall-mount air conditioners and heat pumps, it provides a dependable single pole double throw configuration for switching between two separate circuits based on a defined time interval. This technical component is critical for preventing short-cycling, managing compressor startup delays, and controlling blower run-on times to maximize sensible cooling and equipment life. Its robust housing is built to withstand the thermal stress and vibration typical of outdoor electrical cabinets. Whether you are performing a Bard relay replacement or troubleshooting internal control logic, this time-on-delay relay is the certified solution to maintain original equipment specifications and performance standards.

• Direct OEM Compatibility: Serves as the official Bard replacement relay for part number 8201-045, ensuring exact fitment and electrical sync.
• Enhanced Circuit Protection: Prevents rapid compressor cycling and manages load sequencing to protect sensitive HVAC control boards and motors.
• Versatile SPDT Logic: Single Pole Double Throw design allows for complex switching of auxiliary components, fans, or heating elements during the delay period.
• Industrial-Grade Build: Engineered for reliability in extreme conditions, resisting moisture and high ambient temperatures found in telecom and school HVAC systems.

Is the 8201-045BX a direct drop-in for the older 8201-045 model?
Yes, the 8201-045BX is the manufacturer-specified superseding part number. It is designed to fit the existing mounting footprint and utilize the same wiring pinouts as the original 8201-045 relay.

What is the primary function of this SPDT relay in a Bard unit?
This relay is typically used to manage time-based switching, such as delaying the startup of the compressor after a power interruption or ensuring the indoor blower continues to run for a set period after the cooling cycle ends to capture remaining capacity.

Does this relay require manual calibration of the time delay?
This unit is factory-calibrated to Bard’s technical requirements for specific system protection and sequencing, reducing the risk of improper field adjustments that could lead to equipment failure.
