HONEYWELL HAVDTXX-EU Control Module

Product Description
Honeywell HAVDTXX-EU is a Duct Air Velocity Transmitter used in Honeywell building automation and HVAC control systems. It is designed to measure air velocity and temperature inside air ducts and provide output signals to electronic controllers for ventilation and air-conditioning regulation.

Although often listed as a "Control Module", HAVDTXX-EU is actually an airflow measurement transmitter/sensor, not a PLC controller or standalone control CPU. It is mainly used for HVAC environmental monitoring and automatic air handling control applications.
