Product overview
The XMBA-7000 series intelligent dual input display regulator produced by our company adopts the special integrated circuit developed by ourselves and commissioned by Japanese integrated circuit manufacturers. It not only collects most functions of various regulating instruments in the current automatic control system, but also integrates the CPU, I / D interface, RS485 or RS232 communication interface, EPROM and D / a conversion and other circuits, supplemented by BOCAI This instrument has the following characteristics when used in the software system with numerous advantages, elaborate preparation and repeated debugging.
1. The instrument hardware is greatly reduced, the system structure is relatively simple, the process is significantly improved, there is no flying wire, no debugging potentiometer, all the parameter settings, the instrument calibration function selection are all completed by the software through the keyboard.
2. Four alarm outputs can be set, with more than ten alarm methods. It can be arbitrarily assigned to the main input or sub input, or to the difference between the main input and sub input, or to the sum value of the main input and sub input, or to the quotient value of the main input and sub input.
3. It can be set as one of the switching values to monitor the other three switching values selectively, so as to realize the intelligent acoustooptic alarm function with silencing time.
4. Two or three D / A output ports can be added optionally, which can be allocated to the main input or auxiliary input. The zero point and full degree value of analog output can be set arbitrarily in the displayed value range. The output can be photoelectrically isolated to provide 5V and 24 constant voltage source output.
5. Any complex control, adjustment, alarm, output and other functions can be operated simply by the instrument operator, with the set pressure protected by password, and then it can be used to become a fool instrument. The field operator will not be able to modify the locked parameters. There are four categories and hundreds of levels of anti-jamming modes set by the user, which can adapt to the interference sources of various environments.
Main performance
1. The input signal is thermocouple, thermal resistance and standard linear signal with double input and various graduation numbers, (the double input signal must be the same) or thermal resistance (PT100) and linear signal (please indicate when ordering).
2. The display process quantity exceeds the display range of any setting (- 1999-9999, 9999-1999, 0-3 decimal places) or 0-100%.
3. Triple display of dual input process quantity indication, dual analog bar indication, etc.
4. The display range of double input can be set separately.
5. The display values of main input and sub input can be added, subtracted and divided.
6. Control relay action after comparison between main input and auxiliary input.
7. State output after disconnection, disconnection and disconnection.
8. The state of the relay used for position control after disconnection, disconnection and disconnection has the function of holding.
9. Intelligent audible and visual alarm.
