York S1-024-35715-000 Relay

The York S1-024-35715-000 Relay is a specialized 24VDC SPDT relay engineered for precise switching in residential and light commercial HVACR control circuits. As a veteran-grade OEM replacement part, this Single Pole Double Throw component facilitates reliable changeover logic, typically utilized for sequencing blower motors, condenser fans, or auxiliary heating elements. Its 24V DC coil design ensures seamless integration with standard low-voltage control boards and 24-volt transformers, maintaining electrical isolation between the sensitive control logic and the inductive load side.

Field technicians will appreciate the robust contact ratings, designed to handle the inrush current spikes common in motor-driven applications without premature pitting or welded contacts. The compact footprint of the York S1-024-35715-000 allows for direct mounting into cramped electrical compartments, making it a dependable HVAC relay cross-reference for system restorations. When troubleshooting cycles, verify coil resistance and ensure clean switching between the normally open (NO) and normally closed (NC) terminals to maintain system sequence integrity.

• OEM-Spec Compatibility: Built for direct integration with York control systems, eliminating mounting and wiring discrepancies in the field.
• SPDT Versatility: Provides single-pole, double-throw functionality to manage shared power paths between two different loads.
• Inductive Load Handling: Engineered to withstand the electrical stress of cycling fans and compressors without rapid contact degradation.
• 24VDC Logic: Optimized for low-voltage circuits, ensuring stable operation during the typical voltage fluctuations of an HVAC system cycle.

• Can this be used to replace an AC coil relay? No, this is specifically a 24VDC coil relay. Using it on a 24VAC circuit will cause the coil to chatter and fail. Always verify the output type of your control board before installation.
• What does SPDT signify in this application? It means the relay has one common input and two possible outputs (NO and NC), allowing you to switch power between two different system components or signal paths.
• How do I check for a bad relay? Use a multimeter to check for continuity across the contacts when energized and for the presence of the 24VDC signal at the coil terminals. If the coil generates magnetic pull but the contacts fail to bridge, replace the unit.
