Product Overview/Product overview----------------------------------------------------------◆◆

The DFD/Q-4000 series intelligent operator is an intelligent instrument that can replace the servo amplifier and two instruments in traditional DDZ automation control systems. Adopting on-chip system technology, with a single structure, superior performance, reliable quality, dual digital light column triple display, beautiful and eye-catching, it can be used in conjunction with various intelligent regulators or DCS computer control systems at home and abroad as a backup manual output unit for host failures and maintenance.
This series of instruments is divided into D-type operation, Q-type operation, and hard hand operation.
D-type handheld device
D-type manual controller is a device that calculates the control signal transmitted by the regulator or DCS and the valve position signal feedback from the actuator, and directly outputs forward and reverse electrical signals to drive the motor of the electric actuator. It controls the forward and reverse rotation of the motor and outputs the valve position signal to the regulator. When the operator switches from automatic to manual mode, the status signal of the switch quantity is output to the regulator as the valve position tracking signal. That is, when the regulator receives the manual status signal from the operator, it tracks the valve position.
◆ Q-type handheld device
A Q-type operator is a device that calculates the valve position signal from a regulator or DCS and feedback from an actuator, and outputs a linear current or voltage signal to directly drive the pneumatic valve, control the opening and closing of the valve, and output the valve position signal to the regulator. When the operator switches from automatic to manual mode, the status signal of the switch quantity is output to the regulator as the valve position tracking signal. That is, when the regulator receives the manual status signal from the operator, it tracks the valve position.
◆ Hard hand operation
Hard hand operation is an operator without automatic control, which only receives valve position signals and controls output through human-machine dialogue. The output signals can be forward and reverse electrical signals (D-type hard hand operation) or linear current and voltage signals (Q-type hard hand operation). Receive the valve position signal and display the valve position to determine the valve opening.
