Intelligent Operator

Productoverview:

ZW-DFD/Q series Is a smart meter servo amplifier operator to replace the traditional DDZ type automatic control system in the two meters. Using system on chip technology, single structure, superior performance, reliable quality, double beam three digital display, eye-catching appearance, with a variety of domestic and foreign intelligent regulator or DCS supporting the use of computer control system, fault and maintenance as the host backup manual output unit.

This series is divided into: D type Q type exercises, exercises, and manual control.

1, D type manipulator

D type manipulator is a control signal and the actuator by the controller or DCS send feedback to the valve position signal for operation, motor output directly reversing electrical signal drive electric actuator, control the motor positive inversion, while the output signal to the regulator valve. Automatic / manual operation device, switch state signal output to the regulator, as the regulator valve position signal tracking, i.e. when the regulator receives the manual state signal operator, the regulator valve position tracking.

2, Q type manipulator

Q type operator is a control signal transmitted from the controller and actuator or DCS feedback to the valve position signal after the operation, the linear output current or voltage signal of direct drive pneumatic valve, control valve switch, and the output signal to the regulator valve. Automatic / manual operation device, switch state signal output to the regulator, as a regulator valve position tracking signal, i.e. when the manual operator received signal regulator, regulator of valve position tracking.

3, manual control

Manual control device is a non operating device of automatic control, only receiving valve position signal, the control output through the man-machine dialogue, the output signal can be a positive signal (D manual control) or linear current voltage signal (Q manual control). And through the reception of the valve position signal, valve position display, to determine the valve opening.

Two, application:

ZW-DFD/Q series intelligent operation device for small and medium process device of temperature and pressure and other parameters of single loop control. Can be used in metallurgy, petroleum, chemical industry, building materials, paper, food, pharmaceutical, heat treatment and water treatment and other industrial field.

Three, the main function:

1, the input signal can be arbitrarily selected.

2, automatically boot or boot manual (manual output values can be preset).

3, automatic output.

4, process instructions, control instructions, valve position feedback indicating triple display.

5, can set the upper limit and lower limit output range respectively.

6, valve position feedback value of the analog output.

7, analog output control.

8, EM1 a remote manual function, the initial output value remains unchanged, remote manual function after the cancellation, can keep the manual or automatic state return.

9, EM2 a remote manual function, the initial output values can be preset.

10, valve position feedback error indication, valve position feedback line can automatically enter the manual mode.

11, tracking error error indication.

12, the main input line breakdown control signal output to the motor protection automatic (manual operation control), and outputs the fault alarm signal.

13, the instrument built-in two 40A triac, direct control of actuator motor reversing.

14, the instrument can also be an additional bit type control instrument (universal input). Manipulator with signal input calibration, a calibration instrument uses the E menu.

Four, technical parameters:

1, measurement accuracy: + 0.5%FS+1d + 0.2%FS+1d

2, analog output accuracy: the valve position feedback output and control output + 0.5%FS + 0.5%FS

3, analog output drive the load current signal: 0~10mA = 1.5K; 4~20mA = 750. Signal voltage: 0~5V, 1~5V output impedance is less than or equal to 1.

4, the analog input impedance signal: current: less than 50 ohm; the voltage signal is not less than 500K.

5, manual / automatic: automatic output state is broken through manual;

6, remote manual input EM1: low level switch, EM1 kinetic energy effectively, disconnect the invalid. Remote manual input EM2: low level switch, EM2 kinetic energy effectively, disconnect the invalid.

7, relay contact capacity: AC220V, 3A (resistive load)

8, parameter setting instrument after power-off hold time: more than 20 years

9, insulation strength: AC voltage 1500V, 1 minutes

10, insulation resistance: 50M ohm above

11, power supply: 220V, 50HZ, 6W or 24V
