江苏兰 valve PT-3D-J-phase modulating module is based on the company introduced PT-3C-J-type module on research and development of next-generation three-phase overall electric modulating actuators are designed control module. First, the main technical features Input voltage range: AC340V ~ 420V. Three-phase three-wire, three-phase four-wire system are applicable. ? You can automatically correct three-phase power supply phase sequence and the correct implementation of the valve opening and closing control, drives, users can easily access the actuator electric three-phase power. Input / output signal paths are through the optical isolation (withstand 2000V surge voltage). · Position feedback signal 4 ~ 20mA load resistance: 50Ω ~ 700Ω, Accuracy: 0.5%; third potentiometer adjustment technology once adjusted 4 ~ 20mA feedback signal, greatly simplifying the adjustment process. · Positive action / reaction selection is completed by DIP switch on the module. · Can detect three-phase power phase. When the power phase, closed universal gear, LED warning lights, vertical reduction gear, automatic ban of all electrically operated actuators, three-phase power supply until normal. * If the input signal is lost, the actuator will enable users to advance to the module DIP selected according to the valve remains in situ does not move, or action to the valve fully open position, gasification gear, or action to the valve is fully closed position. Operating temperature range: -20 ℃ ~ + 65 ℃.江苏兰 valve IF, IFM series of intelligent electric equipment I. Features non-intrusive design, the design is simple, intuitive and stroke, torque measurement accuracy, the English language interface of choice for reliable operation with dual speed (slow off) full-featured data Record run self-diagnostic function adaptive fault diagnostic function network transmission motor overheating protection Instantaneous reversal protection to achieve high-speed valve closure requirements Protection class IP (underwater 4 meters 68 hours) with general goods and explosion-proof products two series of long-range radio Bluetooth configuration control function ModBus / ProfileBus bus control intelligent temperature control vertical reduction gearing, the pursuit of excellence-valve (certified), gearing is provided by 江苏兰 valve General Equipment Co.
