DYK2010 Valve Controller

DYK2010 Valve ControllerIt is an intelligent signal acquisition and control system based on industrial microcontrollers, developed by Wenzhou Zhongxuan Instrument Co., Ltd. It is compact in size and can be installed in the junction box of the electric actuator or fixed outside in a DIN rail manner. It can directly receive 4-20mADC signals output by industrial instruments or computers (other input signal types can be customized before leaving the factory), and is matched with potentiometer feedback electric actuators to perform precise positioning operations on various valves or devices.
DYK2010 Valve ControllerTechnical indicators:
Control accuracy: 0.1% -3.0% (adjustable through U4 parameter)
● Can receive feedback signals from electric actuators: potentiometer 500 Ω -10K Ω
● Can receive external control signals (DC): 4-20mA (1-5V, 0-10V, switch quantity, etc. customized before leaving the factory)
Input impedance: 250 Ω;
By modifying the U1 parameter, the following modes can be set: ① DRTA/forward action, RVSA/reverse action mode ② "Interrupt" mode when the input signal is interrupted - OPEN, STOP, SHUT
● Optional: ① Controllable silicon output (AC, 600V, 25A)
② Relay output (AC, 250V, 10A) ◆ Please specify when ordering
● Output actuator position signal: Low drift output 4-20mADC corresponds to actuator fully closed to fully open, signal * is isolated from input (photoelectric isolation), output load ≤ 500 Ω
Environmental temperature: 0-70 ℃, humidity: 35-85%
● The action range of the actuator corresponding to the input signal can be freely calibrated by pressing the button (usually calibrated as the fully closed or fully open position of the electric actuator)
● Can set upper and lower limit points
● Control function for actuator stalling detection: If the control actuator experiences stalling for 3-4 seconds, the locator will disconnect the control output for 1 minute; Repeatedly check and control until the blockage is eliminated.
● Self adjustable accuracy can be set: If the actuator cannot be positioned during operation and vibrates back and forth three times, the locator will automatically reduce the positioning accuracy by 1/1000 (i.e. original accuracy+1/1000) and repeatedly adjust it to the appropriate control accuracy. Set the parameter to U0 (000. x)
Password lock to prevent accidental operation
● Anti actuator frequent startup function
● Indicate the cause of the fault with an error code (E 0X)
Intelligent step distance adjustment and precise positioning based on input signal and actuator angle position
