ZXQJ-M3-3BBS-4 Positioner
Introduction
This series of electric valve intelligent positioner is an intelligent signal acquisition and control system with an industrial single-chip microcomputer as the core. It is small in size and can be installed in the junction box of the electric actuator or fixed outside by DIN rail. It can directly receive industrial instruments or computers, etc. Output 4~20mA or 0-10V signal. It can do accurate positioning operation for various electric actuator valves and devices with internal potentiometer feedback. It can freely calibrate the angle (or displacement) of the electric actuator, and at the same time output the feedback conversion signal of the actuator angle position (or displacement) by 4~20mA or 0-10V. And can accurately set the lower and upper limit value of the angular position of the actuator.
