Large-screen Single-loop Digital Display Controller
Product description
The super-large screen single-loop digital display control instrument is designed on the basis of summarizing and improving the A-series products. It has a more beautiful appearance, and the maximum display size can reach 8 inches. The super-large screen single-loop instrument is divided into two products. One has full-signal switching input and integrates functions such as display, transmission, alarm, and power supply. The other has a digital clock function and displays information such as year, month, day, hour, minute, and second.
【Intelligent Manipulator】
> Product outline
Intelligent manipulator is matching product of PID regulator or DCS and other system, which mainly use to manual regulation under the system running or special condition and to carry out operate as a backup instrument when main machine has happened failure or maintenance. According to field regiurement. it provides high-brightness double LED numeric display or high resolution double light column add double LED numeric display, and 160×80, 96×96 and other exterior installation dimensions selectable by user.
> Mainly technical parameter function characteristic
Intelligent manipulator has manual/automatic control, high/lower amplitude limiting of operation output, follow control and preset control functions and so on. Operational signal has two kinds: one is analog quantity output of direct/reverse action (also called Q type manipulator); the other is direct / reverse revolution switch quantity output (also called D type manipulator), shown as the following block figure (1), (2):
Manipulator signal is analog quantity output (Q type) block diagram (1)
Manipulator signal is direct/reverse revolution (D type) switch quantity output block diagram (2)
1. PID or DCS regulation signal input SVin:
Intelligent manipulator receive the signal of 0～10 mA / 4～20 mA / 0～5V / 1～5V sent from DCS or intelligent regulator.
2. Manipulator signal output
a、Q type manipulator output (Svout): 0～10 mA / 4～20 mA / 0～5V / 1～5V signal, it can directly drive actuator, frequency converter or drive electric regulating valve again from servo amplifier or drive pneumatic thin-film valve from electrical converter and valve positioner. When manipulator is in
automatic work condition, its signal input SVin and operation output signal correspondently is straight-through. in order to realize automatic control of actuator by DCS system or regulator. When in manual work state, its function likes a manipulator, and operational signal output value can direct be modified by increase / decrease key on the panel.
b、 D type manipulator output direct/reverse revolution control signal. When manipulator is in automatic work state, its function likes servo amplifier, it carry out regulating control according to the error of input SVin signal and feedback signal of actuator, to ensure actual valve position is following valve position given signal at once and realize automatic control. When manipulator in manual state, its function likes a manipulator, and by the increase or decrease key on the panel can directly operate direct/reverse revolution output signal for which signal 3 ampere relay normal-open contact or 5 ampere capacity bi-directional thyristor, or SSR trigger signal from DC 3 to 24V and so on may be selected.
3. Feedback or measuring signal input (PVin):
PVin signal is valve position signal sent from actuator (linear analog quantity or resistance signal), or field measuring signal. PVin is universal division number switchable input.
4. Feedback or measuring signal transmit output mA/V (PVout)
PVout output signal transmit output to forestage regulator or DCS system, makes system can monitor actual valve position or field measured value at any moment.
5. State signal output DO:
DO is passive switch quantity signal, when manual control, the manipulator outputs the switch quantity closed signal to forestage DCS system or regulator, after they are received DO state signal, then stop PID operation, and make operation signal output follow valve position feedback signal. After manipulator is switched from manual to automatic control, DO state signal is repealed, DCS system or forestage regulator with current output control value as original value to recover PID control. similarly, when manipulator is switched from automatic to manual control state, with current valve position given value as original value, start manual increment / decrement control, thus manual/automatic, automatic/manual state control switching of the manipulator is all non-interference switch.
6. 232 or 485 communication output
According to different option, manipulator may offer 232 or 485 communication function.
7. Failure or outer set signal DI
Manipulator may offer remote compeling manual input signal, the signal can accept dry node or level signal. and usually connect with failure state signal of the forestage DCS system or intelligent regulator, it is use when the forestage DCS system or intelligent regulator happened fault, the manipulator automatically switch into manual state, and makes value position keeping unchanged, to ensure actual valve position can be controlled in pregiven opening without runaway because forestage regulator or DCS system failure.
8. Alarm output corresponded feedback or measuring signal:
According to different option function and requirement of field control, manipulator may have one alarm (AL1) or two alarm (AL1, AL2) outputs, alarm value are corresponding to display value of feedback or measuring signal (PV).
9. Feed output (P):
According to requirement for system control, manipulator may offer one group or two groups isolated each other capacity for 30 mA of DC 24 V feed.
10. Remote keystroke control function:
According to technology requirement of field control, manipulator can connect with dry node or level control signal supplied for remote operational instrument, its function is the same as each operational key function on the panel.

> Additional explainations for option and wiring diagram
As field control system demand to intelligent manipulator in every function exist difference and limit in installation size and wire terminal number, it is appears that the same terminal marks two or three kinds of different function in above wiring diagram. Like in the wiring diagram (1), No. 7, 8 terminals can defined as state signal output DO (manual closed/automatic break) and alarm output ALM. The instrument calibrate the customer requirement function when out of factory, after leaving calibrate cannot revise. Calibrated function in above each wiring diagram is the function of intelligent manipulator normal meter, otherwise is specific meter, double numeric + double light column display only limited use to 160×80, 80×160 outline dimension instrument. If have unused function can be omitted in the above diagram, for specific meter is by the random wiring diagram shall prevail, when ordering please the customer correct choose mode.
