Trane MOD3105 Relay Board Module ODYSSEY

The Trane MOD3105 Relay Board is a component that is used in HVAC systems. This relay board helps to interface the system’s control board with fans, compressor, and dampers among other electrical parts. It takes low-voltage signals from the control board and in turn, uses these signals to turn on the high-voltage power supply to the connected Relay Board. It receives power at 24V to facilitate safe operation in the HVAC systems without causing any harm to the systems. Advantages include the ability to switch between circuits with Relay Board dependability, easier wiring, and better system control, which translates into increased efficiency.
