The EVD/EVO 24VAC Expansion Board is designed for use in premium HVAC marine air conditioning systems. It interfaces with the main PCO board and typically connects to electronic expansion valves (EEV), sensors, and transducers for a single chiller stage. Note that the display screen is not included. The stage number must be programmed via a screen—most systems share one screen, but if yours lacks one, we can pre-set the stage number before shipping. The PCO handles all other settings through synchronization. Proper grounding is essential using the designated terminal. Dimensions are 4.75" x 2.75" x 2.25". Also identified as Dometic part 263120355, it replaces the Carel EVD0000E51. Contact us for expert support.
