A+RS100/KF30H bus protocol actuator

Basic Working Principle

Intelligent electric actuator, with high speed and low power consumption single chip microcomputer for fang Center intelligent signal acquisition and control unit, for all kinds of valves or

Accurate positioning operation of the device.

The analog signal from the regulator or transmitter is converted to a position positioner, and the position positioner's microcomputer periodically checks this input

Input signal and position feedback signal, when the two signals are unbalanced, once the deviation exceeds the column area, the control signal will be amplified immediately.

Drive the three-phase reversible solid relay or SCR in the intelligent position locator to drive the motor to run in the direction of reducing deviation.

Then drive the reducer well change valve I door opening charge. At the same time, the microcomputer also converts the position signal of valve I door opening into digital pulse signal

Number to the display, from the digital display window can observe the valve opening. It also outputs a mold with a 4-20mA current corresponding to valve] opening charge

Analog signal, current signal and input signal completely isolated, so can adapt to a variety of control system computer or DCS system.

A. To achieve optimal control and improve control performance, it is required to monitor the site and process or stop the machine in time if any failure occurs.

B. Strict control requirements require continuous monitoring of valves or process variables and precise setting and adjustment of diagnostic Wells

Control system.
