Carel evd0000e51 Electronic Expansion Valve Driver

The Carel EVD Evolution EVD0000E51 is a single‑valve electronic expansion valve driver that is part of CAREL’s EVD Evolution family, designed to control an electronic expansion valve in refrigeration and air‑conditioning systems. It communicates over RS485/Modbus to set valve opening and monitor status, enabling precise control of superheat and smooth valve modulation. The EVD Evolution family is described as a versatile solution capable of driving CAREL valves as well as other brands’ electronic expansion valves, with both single‑valve and twin‑valve configurations available; EVD0000E51 represents the single‑valve variant, while a Twin version can operate two valves independently. OEM packaging is available under the CEVD0000E51 designation. This driver sits within CAREL’s EEV technology portfolio for robust integration in commercial and industrial HVAC/R equipment, including applications such as chillers, heat pumps, and commercial refrigeration where accurate valve positioning improves efficiency and control.
