(DV6300B)隔爆型智能定位器采用微处理器和新型压电阀代替传统定位器中的喷嘴、挡板调压系统来实现对输出压力的调节控制。通过CPU运算处理来实现对阀门开度的输入信号和阀位的反馈信号的控制。压电阀由于质量小，可以释放很短的控制脉冲，从而达到很高的定位精度，且压电阀只有在阀门有偏差并执行调节动作时才耗气，所以可以实现低耗能的目的。

retz品牌 Dv6300b flameproof intelligent positioner adopts microprocessor and new piezoelectric valve to replace the pressure regulating system of nozzle and baffle in traditional positioner to realize the regulation and control of output pressure. The input signal of valve opening and the feedback signal of valve position are controlled by CPU operation and processing. Due to its small mass, the piezoelectric valve can release a very short control pulse, so as to achieve high positioning accuracy, and the piezoelectric valve only consumes gas when the valve has deviation and executes the adjustment action, so the purpose of low energy consumption can be achieved.

注意∶

电气线缆必须用屏蔽双绞线或屏蔽线。并将线缆屏蔽层一端连接设备外壳 处的螺钉或壳体内 处的螺钉，另一端连接大地。从而使设备有效接地，防止电磁干扰。Electrical cables must be shielded twisted pair or shielded wire. Connect one end of the cable shielding layer to the screw at the equipment shell or the screw in the shell, and the other end to the earth. Thus, the equipment can be effectively grounded to prevent electromagnetic interference.

电气线缆铺设要远离强磁场环境 Electrical cables should be laid away from strong magnetic field environment.

请在设备断电情况下连接或拆卸电气线缆 Please connect or remove the electrical cables when the equipment is powered off

HART通信接线方式∶将 HART调制解调器或 HART手操器的两根信号线分别接到 4-20 mA 设定信号的正负极上 HART communication wiring mode: connect the two signal lines of Hart modem or Hart manual operator to the positive and negative poles of 4-20 mA setting signal respectively.
