XMDA-6000 Intelligent itinerant display regulator

Product overview

XMDA-6000 series intelligent itinerant display and alarm instrument is no longer a simple itinerant instrument in the past. Most of the products of this series of instruments have strong processing capacity of calculation, comparison, execution, alarm, etc. Xmda-6000 series intelligent itinerant display and alarm instrument adopts a special integrated circuit developed by ourselves and commissioned by Japanese integrated circuit manufacturers. It not only integrates most functions of various kinds of regulating instruments in the day ahead automatic control system, but also integrates circuits such as CPU, I / O interface, EPROM and D / a conversion, supplemented by software that is widely used, carefully prepared and repeatedly debugged The system makes this instrument unique in the following aspects:

1. The instrument hardware is greatly reduced, and the system structure is relatively simple. A variety of input signals are compatible within the scope of user application.

2. The optimized design is adopted, the process is significantly improved, there is no flying wire, no potentiometer adjustment, all the calibration and function setting can be completed by the software through the keyboard.

3. It can be set as four point control plus ten point patrol function. It can be set as unified point alarm or independent separation alarm function.

4. Up to four alarm outputs can be set, and more than ten alarm methods can be used, and sound and light monitoring can be carried out for each alarm point, and the sound of the alarm can be set, and the silencing delay time can be set.

5. The anti-interference modes of nearly one hundred levels in four categories set by the user can adapt to the interference sources of various environments.

Therefore, this instrument has a considerable improvement and breakthrough in various functional levels compared with the ordinary patrol inspection, and its reliability and stability are guaranteed. At the same time, this instrument is not only in line with the current international similar instruments, with a higher performance price ratio, more suitable for the national conditions, which is of great significance to replace imports. 

Working principle

XMDA-6000 intelligent patrol alarm instrument is composed of patrol measurement circuit, digital panel meter, regulator and power supply. The regulated power supply converts the 220V mains power into the stable DC voltage as the other part of the power supply. The itinerant measuring circuit is to select one of the circuits to be tested and send it to a / D conversion and then to jc-588 special central processor for processing. After processing, it is not only to be sent to the digital panel meter, but also to the regulator. After comparing with the set value, it outputs the control or alarm signal according to the regulation law.

Control output and regulation mode


Only check the measured value of each channel, no control


The upper limit and lower limit alarm values are uniformly set for each patrol inspection channel


The upper and lower limit alarm values are set independently for each inspection path


The upper and lower limit alarm values of each patrol inspection channel are displayed by the alarm lights or nixie tubes of each channel respectively


The upper limit and lower limit alarm values of each channel are set independently, which are displayed by the alarm lights or nixie tubes of each channel respectively


The 1-4 channels of the instrument independently use four set values of SP1, SP2, SP3 and SP4, and the 5-16 channels are only for indication


Alarm for upper or lower limit of real-time value or average value (SP3 and SP4)


SP3's set value monitors the upper and lower limit alarms of all patrol points


Four set points (SPI, SP2, SP3 and SP4) can be specified for each channel (at most two set points can be specified for one channel)
