Overview
The KMC Controls XEC-3001 is an electronic-to-pneumatic (E/I-P) transducer that converts analog voltage or current signals into linear pneumatic output signals. Used primarily in HVAC systems, this transducer enables precise positioning of damper and valve actuators through branch line pressure feedback. The unit is neither position-sensitive nor directional, making it flexible for various building automation applications.
