Resideo RT850T-240 Relay
The Resideo RT850T-240 Relay is a professional-grade solid state relay engineered for precise control of line voltage resistive loads in electric heating applications. Built to handle 208/240 Vac input voltage, this unit features an integrated 24 Vac transformer, making it a self-contained solution for contractors upgrading or repairing baseboard and radiant systems. The TRIAC switching mechanism ensures 100% silent operation, eliminating the mechanical "click" associated with traditional contactors while providing an operating humidity range of 0-95% RH. This relay is fully compatible with 2 or 3 wire thermostats and optimized for 15-second cycles to provide tighter temperature regulation. Professionals will appreciate the 24 Vac control signal and the visual LED indicator for immediate load switching confirmation. With a temperature rating of -4 to 140 degrees Fahrenheit, this HVAC electric heating relay maintains high reliability in diverse mechanical room environments.
Key Benefits- Integrated Transformer: Built-in 24V transformer simplifies installation by eliminating the need for external power sources for the control circuit.
- Silent TRIAC Switching: Ideal for residential bedrooms and quiet commercial zones where mechanical relay noise is unacceptable.
- Thermostat Versatility: Seamlessly interfaces with 2-wire mechanical, battery-operated, or 3-wire (R, C, W) digital thermostats.
- Enhanced Precision: Supports short-cycling (15-second cycles) to minimize temperature swings and improve occupant comfort.
- Rugged Construction: Designed for an ambient temperature rating up to 140°F and fits standard 4x4 electrical boxes.
Is the Resideo RT850T-240 compatible with smart thermostats?
Yes, because it includes a built-in transformer and supports 3-wire (R,C,W) connections, it is compatible with most 24V smart thermostats that require a C-wire for power.
Can I use this relay for inductive loads like motors?
This solid state relay is specifically rated for resistive loads (up to 23A). For inductive motor loads, verify the inrush current requirements against the TRIAC specifications before installation.
Does this unit require a specific mounting orientation?
For optimal thermal management, it is recommended to mount the relay on a standard electrical box with the heat sink fins positioned to allow for natural convection.
