PT-3D-J-type regulating valves dedicated servo module? First, adjust the servo valve dedicated Module Overview PT-3D-J-phase modulating module is based on the company introduced PT-3C-J modules on a whole new generation of three-phase modulating electric actuator control module dedicated research and development. DC4 it receives from the DCS or PLC systems such as controllers ~ 20mA standard current signal to control the ratio of the electric actuator to complete the valve opening degree of regulation. The product is set to automatically adjust the phase sequence, proportional control, isolation amplifier, valve position transmitter, power driver and many other functions in one, with a lack of protection, over-torque protection, electronic interlocking protection movement ban delay protection, throwing the letter protection temperature protection, improved protection. Also increase with the scene button board to implement a variety of field operations and provide alarm outputs; increase with the valve position LCD display visually accurate valve opening; increase with an infrared remote control, to achieve a higher degree of protection of the site operator. The product has a strong anti-jamming capability, reliable performance, shock, moisture, small, simple wiring, convenient debugging. On DKJ, DKZ, DZW, LQA, QB, QT, SD, SM, SMC, SR, 2SA, 802,903,3410,3610 other products are now widely used. Second, adjust the servo valve module dedicated main technical parameters and performance characteristics of a power supply voltage: 380V ± 10%, 50HZ ± 5% (special request can be made when ordering). 2, the power wiring: three-phase three-wire, three-phase four-wire system. 3, can automatically identify, adjust the three-phase power supply phase sequence, and the correct implementation of the valve opening and closing control. 4, with a lack of protection, over-torque protection, electronic interlocking protection movement ban delay protection, throwing the letter protection, temperature protection, improved protection. 5, can be equipped with: Live button panels, valve position LCD display, infrared remote control and other functions. 6, to provide two sets of dry contact output: a set of integrated alarm (power, phase, over torque, throw the letter) a set of remote / field status indication. 7, the input / output signal channels are opto-isolated (2000V surge withstand voltage). 8, the input signal: DC4mA ~ 20mA. 9, the output signal: DC4mA ~ 20mA. 10 input channels Impedance: 150Ω (DC4mA ~ 20mA), ≧ 500KΩ (DC1V ~ 5V). 11, the output current load resistance: ≦ 750Ω. 12, fit the valve position potentiometer resistance: 1KΩ. 13, the output current of the valve larger adjustment range: 0% to 85% of the low end, i.e. without the low end to zero position; high of 15% to 100%. That is when the lap valve position potentiometer adjustable angle are smaller between the DC4mA ~ 20mA (0 ~ 45 °), or the maximum angle (0 ° ~ 270 ° or 0 ° ~ 330 °). 14, the unique current feedback control technology simply valve opening and closing time, you can accurately align DC4 ~ 20mA current, without the traditional pattern repeats regulation. 15, can be set via DIP switches on the module action and reaction: Positive control current of 4mA valve is fully closed, 20mA corresponds to the fully open valve effect; reaction 20mA control current corresponding valve is fully closed, 4mA corresponding valve is fully open. 16, can be set via DIP switches on the module control current signal is lost when the three operating states: remain in place, fully open, fully closed. (Note: When the control current is less than 2mA, regarded as a loss of signal). 17, suitable for reversible control, turn sustained rate of 50%, the number of turns per hour ≦ 1200 times. 18, sensitivity: 0.3 ~ 20% adjustable. 19, operating temperature: -30 ℃ ~ +70 ℃ (special temperature requirements, please call the contact). 20, humidity: ≦ 95% (25 ℃).
