Function:

1Free selection of input signals. Triple display of process quantity, control quantity, and valve position feedback. Square opening and small signal resection can be performed.

2Choose between automatic or manual startup mode (the output value for manual startup can be pre-set).

3Two remote manual functions. （EM1，EM2Remote manual function)

4TheDFDThe hard manual operation function of the console andDFQThe remote manual automatic switching function.

5Hand automatic output.

6The upper and lower limits can be set separately to control the amplitude range of the output.

7Has motion sensitivity settings.

8The analog quantity of valve position feedback can calibrate the zero point and full degree.

9Can choose to simulate the positive and negative effects of the input signal and valve position feedback analog output signal. （0%~100%and100%~0%Mutual Conversion

10The valve position feedback simulates the output reaction to achieve timely tracking of hard manual operation or automatic switching on the control panel.

11It has the braking function of motor forward and reverse control, and the valve position feedback fault can be output by relay.

12Valve position feedback tracking fault flashing alarm indication (tracking allowable error can be set).

13Dual analog outputs of valve position feedback analog quantity and control analog quantity.

14Built in instrument panel2road41AThe bidirectional thyristor directly controls the forward and reverse rotation of the actuator. Servo motor forward and reverse rotation time0.0~25.0SAdjustable. （DFD）

15Control the execution mechanism in both forward and reverse directions15Within seconds, if there is no change in valve position feedback, the strong current output will be automatically cut off（DFD）

16Can provide multi host, single host, and no host modesRS485Asynchronous serial communication method. Communication data verification followsCRC-16American data communication standard, high reliability cycle, barcode verification.
