York S1-024-27542-000 Relay

The York S1-024-27542-000 Relay is a mission-critical 24V DPDT relay designed for precise switching in residential and light commercial HVAC systems. This Double Pole Double Throw switching relay features a 24VAC coil, making it an essential component for controlling secondary circuits, blowers, or compressors in York, Luxaire, and Coleman equipment. As a direct OEM replacement HVAC relay, it ensures proper contact alignment and electrical isolation, preventing voltage bleed across circuits. Integrating this DPDT 24V coil relay into your control string allows for the simultaneous management of two separate circuits, a common requirement for complex sequencing or interlocking safety controls. Whether you are troubleshooting a York furnace relay replacement or upgrading a control board interface, this component provides the inductive load handling and low-resistance path necessary for long-term system reliability. Professional installation ensures that the high-amperage contacts operate within their rated duty cycle for peak performance.

• Dual-Circuit Control: The DPDT configuration allows for versatile switching of two independent power sources or signals simultaneously.
• Precise 24V Actuation: Optimized for standard HVAC control transformers, ensuring reliable pull-in and drop-out voltages.
• OEM Compatibility: Specifically engineered for York-family equipment, ensuring the correct footprint and terminal orientation for fast field installation.
• High-Contact Integrity: Constructed to resist carbon tracking and contact pitting, even under frequent cycling in inductive load applications.

What is the primary function of the York S1-024-27542-000 in a furnace or air handler?
This relay is typically used to interface the low-voltage thermostat signal with high-voltage components like blower motors or to provide dry contacts for auxiliary system interlocking.

Can I use this relay as a substitute for a SPDT relay?
Yes, a DPDT relay can replace a SPDT relay by using only one set of contacts, provided the coil voltage and contact amperage ratings meet or exceed the original specifications.
