The PT-2D-J single-phase regulating module is a new-generation single-phase integral regulating electric actuator special control module developed on the basis of the PT-2C-J module introduced by our company. It receives DC 4 ~ 20mA standard current signal from DCS or other systems or PLC controllers, and controls the electric actuator to complete the proportional adjustment of the valve opening degree. The product set, proportional adjustment, isolation amplification, valve position transmission, power drive and many other functions, with over-torque protection, electronic interlock protection, forbidden delay protection, loss of confidence protection, temperature protection and other perfect protection functions. . It can also be equipped with on-site button board to implement on-site operation and provide various alarm output; add valve position liquid crystal display to accurately display the valve position opening degree; add infrared remote control to achieve higher protection level on-site operation. The product has the advantages of strong anti-interference ability, reliable performance, shock resistance, moisture resistance, small size, simple wiring and convenient debugging. It has been widely used in DKJ, DKZ, DZW, LQA, QB, QT, SD, SM, SMC, SR, 2SA, 802, 903, 3410, 3610 and other products.
