Markel 51135001 Relay
The Markel 51135001 Relay is a specialized 24V fan time delay relay engineered for precise sequencing in commercial and residential HVACR applications. As an OEM-specified component, it utilizes advanced bimetal disc technology (comparable to Therm-O-Disc 15S1) to manage the operational timing of indoor blowers, exhaust fans, and cabinet unit heaters. This HVAC ventilation control device ensures that the fan continues to run for a designated period after the heating or cooling source de-energizes, facilitating complete heat dissipation and vapor purging while maximizing total system energy efficiency.
Designed for seamless integration with 24VAC/DC control circuits, the 51135001 features a compact footprint ideal for tight wiring enclosures and control boards. By preventing sudden motor stoppage, this low voltage timer relay protects sensitive system components from thermal stress and short cycling. Whether you are performing a Markel 51135001 replacement or upgrading a custom ventilation sequence, this relay provides the reliability required for continuous-duty industrial environments and high-cycle HVAC equipment.
Key Benefits:- Optimized Heat Transfer: Delays fan shutdown to extract residual heating or cooling from coils, improving overall SEER/HSPF ratings.
- Equipment Protection: Mitigates rapid cycling and reduces mechanical wear on blower motors and contactors.
- Broad Compatibility: Specifically designed for FCH3D05 series heaters and adaptable for various 24V ventilation and air handling systems.
- Industrial-Grade Build: Rugged construction ensures stable timing characteristics even in harsh temperature environments.
- Simplified Installation: Standard terminal configuration allows for direct field replacement in existing control loops.
- Will this relay work with both AC and DC 24V systems? Yes, this unit is engineered to operate within 24V control circuits, commonly found in standard HVAC 24VAC transformers and DC-powered industrial fans.
- Is this an "on-delay" or "off-delay" relay? The 51135001 typically operates as a delay-off timer, ensuring the fan runs on after the thermostat call ends to purge the system.
- Can I use this for non-Markel equipment? While optimized for Markel unit heaters, it is a versatile 24V fan timer that can be integrated into any system requiring similar timing and voltage specifications.
