: XDFD / Q Series Smart Communicator :
It is an instrument that can replace the operator and servo amplifier in the traditional DDD-type automation control system. Using system-on-chip technology, simple structure, superior performance, reliable quality, double digital plus light beam triple display
It is beautiful and eye-catching, and can be used with various domestic and foreign regulators or DCS control systems as a backup manual operation output unit for host failure and maintenance. This series of instruments are divided into: D type operation, Q welcome operation, hard hand operation.
The D-type hand-held actuator is operated by the control signal sent by the regulator or DCS and the valve position signal fed back by the actuator, and then directly outputs the positive and negative electrical signals to drive the electric actuator to control the positive and negative rotation of the motor.
Output the valve position signal to the regulator. When the operator automatically turns to manual, it outputs the status signal of the switching value to the regulator, which acts as a valve position tracking signal for the regulator.
输出线性电流或电压信号直接驱动气动阀，控制阀门的 The Q-type hand-held manipulator is operated by the regulator or DCS to send control signals and valve feedback signals from the actuator. The intelligent hand-held manipulator outputs a linear current or voltage signal to directly drive the pneumatic valve.
Switch and output valve position signal to regulator at the same time. When the operator automatically turns to manual, the state signal of the switch value is sent to the regulator, which serves as the valve position tracking signal.
The hard hand operation is an operator without automatic control. It only receives the valve signal and controls the output through human-machine dialogue. The output signal can be a positive and negative electrical signal (D-type hard hand operation) or a linear current and voltage signal. Fuck.
The valve opening position is determined by receiving the valve position signal and displaying the valve position.

从功能上分有纯手操和手自动手操两种类型，纯手操只与电动执行器相连接，通过面板开关按键直接控制执行机构的正、反转，具备手自动功能的 There are two types of intelligent manual operator: pure manual operator and manual automatic operator. Pure manual operator is only connected with electric actuators. It can directly control the forward and reverse of the actuator through the panel switch keys. It has the manual automatic function. of
The Communicator is installed between the actuator and the controller (regulator or computer-controlled DCS, PLC system). When the Communicator is in the manual state, the actuator is directly controlled by the Communicator. When in the automatic state, the actuator is controlled Right of hand
To the controller, the current and voltage signals from the controller are converted into switching signals or isolated control current and voltage signals to control the action of the electric actuator or electric valve positioner. From the control signal type, the communicator is divided into D type and
There are two types of Q-type. The D-type handheld programmer contains a servo amplifier. The forward and reverse of the DKJ and other series of electric actuators are controlled by manually pressing the keys on the panel. Control current
Electronic actuator or electric valve positioner of servo amplifier.
Second, the main features
The D-type handheld communicator contains a servo amplifier to directly drive the DKJ and other actuators controlled by the forward and reverse switch of the power supply. Q type can output isolated control current and voltage signals, and its high isolation of output current and voltage signals can guarantee
Control and stabilize the charged actuators. The valve position limit amplitude can be set to ensure that the actuator runs safely within the set safety valve position range. Valve position control action sensitivity can be set to prevent frequent movement of the actuator to ensure
Actuator life. With manual / automatic switching function, it is widely used in computer, regulator or DCS, PLC and other automatic control systems. With manual automatic status relay output. Valve position feedback signals can be current,
Voltage, variable resistance and other forms of input, suitable for all types of actuators.
