Bard HVAC 8201-008BX Relay

The Bard HVAC 8201-008BX Relay is a specialized 24V SPST normally open relay designed for high-reliability switching in Bard wall-mount air conditioners and heat pumps. This OEM Bard replacement relay is the direct engineering successor to the 8201-008, maintaining identical electrical characteristics while ensuring a precise fit within the control box. Rated for 8 FLA at 250V, this heavy-duty component is typically utilized to sequence fan motors, compressor contactors, or auxiliary heat kits. In the field, technicians rely on this electromagnetic relay to resolve common service issues like chattering contacts, intermittent blower operation, or failure to initiate the cooling call. The single-pole, single-throw configuration provides a clean "make" or "break" for the load circuit, preventing voltage drops across the terminals. When troubleshooting, verify the 24V coil resistance and check for continuity across the normally open contacts during a call for stage 1 cooling or heating to ensure the switching control relay is responding to the thermostat signal.

• Direct OEM Replacement: Replaces the discontinued 8201-008 with no modifications required to the mounting bracket or wiring harness.
• Optimized Load Handling: Rated at 8 Amps for 250V applications, making it suitable for both 208/230V and 120V circuits.
• Simplified Diagnostics: Standard 1/4 inch spade terminals allow for rapid multimeter testing and lead connection.
• Reliable Sequencing: Engineered to handle the high-cycle demands of commercial and modular HVAC environments without contact welding.

• Is the 8201-008BX compatible with older Bard units? Yes, it is the official manufacturer-designated replacement for the original 8201-008 and is backwards compatible with all units calling for that part number.
• What does the normally open (NO) status mean for my circuit? The contacts remain open until the 24V coil is energized by the control board or thermostat, at which point it closes to complete the high-voltage circuit.
• Can I use an 8201-008BX to replace a different SPDT relay? No, this is an SPST (Single Pole Single Throw) relay. If your wiring diagram requires a changeover contact (SPDT), you must use the specified SPDT part to maintain sequence logic.
