DSM modular intelligent electric valve controller, the use of advanced micro-processing technology, high integration of IC chips and long-life power output devices, to accept from the host instrument DC4 ~ 20mA adjustment signal and the lower electric actuator DC4 ~ 20mA valve position feedback Signal (or potentiometer "three-wire" signal), the output "on" and "off" signal to achieve the valve opening control and regulation. DSM modular intelligent electric valve controller, with digital setting, display, limit, motor stall protection, break alarm and valve self-calibration and other advanced features. Stable and precise control of the valve, damper and damper adjustment structure. Can be widely used in power generation, metallurgy, petroleum, chemical and other fields. The DSM Modular Smart Electric Valve Controller can be used with single-phase AC motor actuators such as the DKJ and DKZ actuators, but also with actuators and actuators for three-phase AC motors. DSM modular intelligent electric valve controller with the use of the traditional electric valve, the reliability, stability, accuracy, etc. can be increased several times more, for the transformation and upgrading of the old electric actuator has brought a new life. main feature: Intelligent calibration: The valve opening and valve position output current "zero" and "full" calibration, no need to adjust the potentiometer, no need to use the basic measurement instruments for complex debugging, as long as the valve in the actual "off "And" fully open "position by pressing the button, it automatically correct the newly set range of 0-100% and DC4-20mA. Digitally set the valve electric zone parameters, minimum overshoot, good stability, high control accuracy. Open to freedom: to change the valve opening and valve mode, no need to change any wiring, set by the button to complete. Intelligent step: to avoid oscillation or too "red" phenomenon, improve control accuracy. Super error detection and alarm function: In the event of actuator failure, the intelligent error detection and alarm function can automatically detect and alarm, display the cause of the actuator failure, accurately indicate the operating status of the actuator. Depending on the cause of the fault, the display of different alarm signals will greatly shorten the time required for the user to eliminate the fault and return the actuator to its normal working condition as soon as possible. Automatic phase protection: Previously, in the field wiring, the phase sequence of the three-phase alternating current supplied to the actuator must be guaranteed to be correct because once the phase sequence is wrong, the motor will rotate incorrectly and damage the valve and the actuator. Users can now save this trouble, no longer need to consider the phase sequence wiring problems. When the phase of the field wiring is reversed, the phase synchronizer will automatically correct the phase to ensure that the valve is executed in the direction of the command. That is to say, the actuator always rotates in the pre-set opening direction when it receives the opening command, and will not run in the opposite direction due to the phase sequence exchange. Abnormal protection: Motor overcurrent protection: When the actuator motor is running, the motor overcurrent due to various reasons, DSZH220 will automatically stop the motor. Instantaneous reverse protection: When the actuator is turning in one direction, for example, the valve opening operation is being executed. If the valve closing command is received, the control logic inside the actuator will be delayed for a preset period of time before the valve closing command is executed . This technology will reduce the impact of motor current, extend the life of power components, while preventing the impact load on stem, gear box and other mechanical transmission may cause damage, and thus effectively protect the motor.
