Trane RLY1873 Relay
The Trane RLY1873 Relay is a heavy-duty, field-proven 24V DPDT Interlock Relay designed for critical switching applications in commercial and residential HVAC systems. This OEM double pole double throw relay provides precise mechanical switching of 125VAC/250VAC circuits, making it an essential component for interlocking cooling and heating stages or managing safety circuit shutdowns. Rated for 10 Amp inductive loads, the RLY1873 ensures reliable terminal contact and logic-level isolation across separate voltage circuits within the control board assembly. Its compact 3.5-inch footprint allows for low-profile mounting in tight electrical enclosures, supporting seamless integration into existing Trane air handlers and packaged units. Whether you are troubleshooting an HVAC interlock circuit or performing a direct RLY01873 replacement, this genuine 24V coil relay maintains system integrity by preventing simultaneous operation of conflicting components and re-establishing factory-spec performance parameters.
Key Benefits:- Universal Compatibility: Serves as a direct OEM replacement for the discontinued RLY1873 and the current RLY01873 part numbers to ensure drop-in installation.
- Enhanced Circuit Protection: The 10A DPDT configuration enables independent control of two separate circuits, ideal for complex blower and compressor sequencing.
- Technical Reliability: Engineered to withstand the thermal cycling and high-frequency switching typical of demanding HVAC environments.
- Precise Interlocking: Guaranteed to align with manufacturer timing and safety protocols for system-wide coordination.
- Can I use this to replace a single pole relay? No, this is a DPDT relay; while it can perform SPST or SPDT functions, you must ensure the 24V coil and amperage ratings match your specific schematic requirements.
- What does the 'Interlock' feature do? It safely links the operation of two different components, ensuring one cannot activate unless the other is in the correct state, preventing equipment damage.
- Is the RLY1873 compatible with 120V systems? The coil requires a 24V AC signal for activation, though the contacts are rated to switch loads up to 250VAC.
Disclaimer: While we strive for 100% accuracy, product data and specifications are subject to change. Please contact our team to confirm compatibility or technical details before purchasing.
