Trane RLY2138 Relay
The Trane RLY2138 Relay is an essential OEM industrial-grade component for precise 24V HVAC control. This robust 1NO/1NC relay (normally open/normally closed) is engineered for switching high-current loads in Trane air handlers, furnaces, and light commercial packaged units. Featuring high-conductivity silver cadmium oxide contacts, the RLY2138 is rated for up to 25A at 277 VAC, providing reliable SPST performance with a 7FLA/42LRA inductive rating. Its compact phenolic enclosure and quick-connect terminals streamline field replacement in tight control boards or universal bracket mountings. Whether you are troubleshooting a stuck fan relay or managing multi-speed fan sequencing, this 24-volt actuator ensures crisp electrical switching across diverse operational environments. Designed to maintain the precise logic of Trane control circuits, it mitigates common failures like contact arcing or welding under high duty cycles. For veteran contractors, this exact-fit replacement relay is critical for restoring system efficiency and preventing erratic blower motor behavior.
Key Benefits for HVAC Professionals- Engineered for Versatility: Dual contact configuration (1 Form A / 1 Form B) supports diverse HVAC control logic and interlocking.
- Heavy-Duty Construction: Rated for high-amperage applications with a 25A current rating and thermal-resistant phenolic housing.
- Exact OEM Fit: Ensures seamless physical and electrical integration, replacing part numbers RLY02138 and X13300552020.
- Fast Response Time: Optimized 25ms operate/release timing prevents fan status delays and system short-cycling.
- Broad Compatibility: Suitable for multi-pole configurations in VCEF and BCHD series Trane rooftop units and air handlers.
What are the coil voltage and contact ratings?
The coil operates on a standard 24VAC signal with a 0.17A draw. Contacts are rated for 25A and up to 277V switching voltage, making it ideal for high-voltage fan motors and auxiliary heat kits.
Can this relay replace a 2-pole or 3-pole relay?
This is an SPST 1NO/1NC relay. For 3-pole or high-amperage contactor replacements, verify your existing wiring schematic as this unit is specific to single-pole control signaling.
What causes this relay to stay "stuck" closed?
Excessive contact arcing or voltage spikes often cause the internal contacts to weld together, leading to blowers that run constantly even when the thermostat is off. Replacing with a genuine RLY2138 restores proper circuit isolation.
