Features:PT-3D-J-type three-phase adjustment module, R & D in the module I introduced the PT-3C-J on the basis of the overall regulation of the new generation of three-phase electricActuator-specific control module. It receives from DCS and other systems or PLC controller DC4 ~ 20mA standard current signal, and control of electric actuatorsCompletion of the degree of valve opening ratio adjustment. The product set of the phase sequence automatically adjust the proportional control, isolation amplifier, and valve position transmitter, power-drivenMany features in one, with the lack of protection, over-torque protection, electronic interlock protection, ban dynamic delay protection lost letter of protection, temperature protection and other finishedGood protection. Site control panels can be added with the implementation of site operations and provide a variety of alarm output; increase with the valve position LCD display, accurate straightConcept shows the valve opening; plus with infrared remote control, to achieve higher protection level of field operation. The product has a strong anti-jamming capability, performance can beRely on, seismic, moisture, small size, simple wiring, convenient debugging. Has been widely used in the DKJ for DKZ the DZW, LQA, QB,QT, SD, SM, SMC, SR, 2SA, 802,903,3410,3610 and other products.
型号:PT-3D-J, PT-3C-J.
Main technical parameters:A power supply voltage: 380V ± 10%, 50HZ ± 5% (special requirements can be when ordering).2, the power wiring: three-phase three-wire, three-phase four-wire system.3 can automatically recognize, adjust the three-phase power, phase sequence, the correct implementation of the valve open and closing control.4, the lack of protection, over-torque protection, electronic interlock protection, ban dynamic delay protection lost letter of protection, temperature protection, perfect protection function.5 can be equipped with: site control panels, valves LCD screen, infrared remote control and other functions.6 provides two sets of output dry contacts: a comprehensive set of alarms (power, phase loss, over torque, throw the letter) a group of remote / live status indication.7, the input / output signal channel optical isolation (withstand 2000V surge voltage).8, the input signal: DC4mA ~ 20mA, DC1V ~ 5V, DC0V ~ 10V (can choose one of them).9, the output signal: DC4mA ~ 20mA, DC1V ~ 5V, DC0V ~ 10V (can choose one of them).10, input channel impedance: 150Ω (DC4mA ~ 20mA), ≥ 500KΩ (DC1V ~ 5V).11, the load resistance of the output current: ≦ 750Ω.12, the adapter valve-bit potentiometer resistance: 1KΩ ~ 5KΩ (if with other resistance potentiometer, please contact me).13, a larger adjustment range of the output valve position current: low-end 0% to 85%, ie, the low-end without to zero; high-end 15% to 100%. That is, when the lap of valve position potentiometerDevice corner small (0 to 45 °) or between the corner of the maximum (0 ° to 270 ° or 0 ° ~ 330 °) are adjustable DC4mA ~ 20mA.14, the feedback current regulation technology just the valve open, off time, you can accurately align the DC4 ~ 20mA current, without the traditional way repeated adjustment.15, can be set via DIP switches on the module is action and reaction: positive role of the control current of 4mA corresponding valve is fully closed, 20mA corresponds to the valve is fully open;Reaction control current of 20mA corresponds to the valve is fully closed, 4mA corresponds to the valve is fully open.16, can be set via DIP switches on the module control current signal loss of the three modes of operation: stay in place, fully open, fully closed. (Note: When the controlCurrent lower than 2mA, regarded as a loss of signal).17, applied to reversible control, connected to the sustained rate of 50% per hour connected to the number of ≦ 1200.18 Sensitivity: 0.3 to 20% adjustable.19, Operating Temperature: -30 ℃ ~ +70 ° C (special temperature requirements, please call the contact).20, the ambient humidity: ≦ 95% (25 ° C).
