The ABB 18345-2022521001 Pneumatic Valve Positioner, TZID-C, accepts a 4-20 mA control signal and converts it into proportional pneumatic output to position a valve actuator. In a control loop, it refines the setpoint to achieve accurate valve opening and closing for process automation. This model is identified by ABB part number 18345-2022521001 and is designed for industrial systems that require 4-20 mA signal conditioning and precise pneumatic actuation.
