Description：
Intelligent inspection instrument used with all kinds of sensors, transmitters, but at the same time of 8 goods 16 road such as temperature, pressure, liquid level, flow, weight industrial process parameters detection, alarm control, analog output circuit, data acquisition and communication.
One, the multiplex circuit display apparatus function characteristics:
1. Universal input function;
2. Automatic calibration and manual calibration function;
3. Multiple protection, isolation design, strong anti-interference ability, high reliability;
4. Good software platform, and have the ability to develop secondary and to satisfy the special function;
5. Advanced modular structure, with the powerful instrument chip, function combination, the system upgrade is very convenient;
6. Automatic checking and manual missile d etection can switch freely;
7. Checking the channel switching time and effective number can be set.
Second, the intelligent inspection instrument main technical indicators:
1. The basic error: 0.2% FS + 1 word;
2. Points distinguishes the force: 1/20000, 14 A/D converter;
3. The display mode: double row four LED digital tube, display on the measured values, discharge according to the channel number;
4. The sampling period: 0.5 S;
5. Alarm output:
(1) 1 ~ 16 channels on the lower limit alarm, AC220V / 3 a relay contact output capacity;
2 1 ~ 8 channel respectively independent alarm, relay contact output capacity AC220V / 1 a;
6. Analog output: through the switch input and choice of the corresponding channel with 4 ~ 20 ma, 0 ~ 10 ma, 1 ~ 5 v, isolate the output precision: 0 ~ 5 v + / - 0.3% FS.Output: 7. Communication interface way - isolated bi-directional serial communication interface RS485 / RS422 / RS232 / Modem;
8. Set baud rate - 300 ~ 300 BPS internal freedom;
9. Electricity source, switching power supply of 85 ~ 265 vac power consumption below 4 w.
Three, intelligent inspection instrument selection table:
