DSM modular intelligent electric actuator valve controller, using advanced microprocessor technology, high integrated IC chip and long life power output device, receive from the upper instrument DC4~20mA regulating signal and lower electric actuator DC4~20mA valve position feedback signal (or potentiometer “three-wire” signal) , output “open” and “close” signal, to achieve the control and regulation of valve opening. DSM modular intelligent electric valve controller has advanced functions such as digital setting, display, limit position, motor stop-up protection, off-line alarm and valve self-calibration. The valve, damper and baffle can be controlled stably and accurately. Can Be widely used in power generation, metallurgy, petroleum, chemical and other fields.
DSM modular intelligent electric actuator valve controller can not only be used with single-phase electric power actuators (such as DKJ and Dkz) , but also with three-phase electric power actuators, electric devices. The DSM modular intelligent electric valve controller, when used in combination with the traditional electric valve, can improve several times in the aspects of feasibility, stability, accuracy and so on, which brings new vitality to the transformation and improvement of the old electric actuator.
Main Features:
● Intelligent Calibration: No need to adjust the potentiometer, no need to carry out complex debugging with the reference measuring instrument when calibrating the “zero” and “full” of the valve position opening and the output current As long as the actual “full-closed” and “full-open” position of the button once, in order to set the new interval automatically accurate correction to 0-100% and DC4-20MA.
● The parameters of valve electric region can be set digitally, the overshoot is minimum, the stability is good, the control precision is high.
● Freedom Of Opening: When changing the opening direction of the valve and the way the valve operates, no need to change any wiring, it can be done by setting the button.
● Intelligent Step: It can avoid oscillation or overshoot, and improve control precision.
● Super Function Of Error Detection And Alarm: Once the actuator fails, the intelligent error detection and alarm function can automatically detect and alarm, show the cause of actuator failure, accurately indicate the operating state of the actuator. According to the different fault reasons, displaying the different alarm signals, will greatly shorten the time that the user removes the fault, as soon as possible will the actuator return to the normal working state.
● Automatic phase protection: Previously, in field wiring, it was necessary to ensure that the three-phase electric power supplied to the actuator was in the correct phase sequence because if the phase sequence was wrong, it would cause the motor to rotate incorrectly, thereby damaging the valve and the actuator. Now the user can completely eliminate this trouble, wiring no longer needs to consider the phase sequence. When the field connection phase is reversed, the synchronizer automatically corrects the phase to ensure that the valve operates in the direction indicated. That is, when the actuator receives the open command, it always rotates in the preset open direction, and will not run in the opposite direction because of the phase sequence switch.
