Intelligent circuit display regulator

Products overview:

ZW - XMDA seriesIs no longer a simple sense of the survey, most of the series of instrument products have strong operation, such as comparison, execution, alarm processing capacity.Instrument adopted the self-developed entrust integrated circuit manufacturers custom development, and production of specialized integrated circuit, it not only collected has most of the function of automatic control system of regulating various instruments, but also integrates the CPU, I/O interface, such as EPROM and D/A conversion circuit, supplemented by being open, elaborate, repeatedly debugging of software system make the meter has the following characteristics:

1. Instrumentation hardware are greatly reduced, the composition of the structure is relatively simple.Within the scope of the user application, a variety of input signal is compatible.

2. Using the optimized design, the technology is improved significantly, no fly line, no adjustment potentiometer, and all of the calibration function set can be finished all through the keyboard by software.

3. Can be set up for four type control plus ten site inspection function.Can be set up for the separation of unified alarm or independent alarm function.

4. Can set up four alarm output, alarm method can reach more than 10, and but for the sound and light alarm point monitoring, and to the sound of the alarm, setting the silencing delay time.

5. Then the user has set itself the four categories of nearly hundred kinds of levels of anti-interference mode, can adapt to various environmental interference sources.

Therefore the meter, compared with ordinary type patrol functions level there is a considerable improvement and breakthrough, its reliability, stability, and has considerable promise, at the same time, the instrument not only with the current international similar instrument, high cost performance, more suitable for national conditions, is of great significance to replace imported.

Second, the working principle:

ZW - XMDA series intelligent circuit display apparatus is composed of circuit measurement circuit, digital panel table, controller and power supply parts.Regulated power supply will be 220 v mains other parts into a stable dc voltage as the power supply.Circuit measurement circuit is selected after all the way from the circuit being measured for A/D converted to JC - 588 dedicated CPU processing, not only to send to the digital panel table, but also to send to regulator, after compared with the set value by adjusting regularity of output control or alarm signal.

Three, the main functions:

1, the input signal types: thermocouple, heat resistance, linear current and linear voltage.

2, inspection channel number: 1 ~ 32.Four road measurement instrument can be displayed at the same time.

3, but inspection, missile d etection, channel show time setting switch, 0.1 ~ 25 s optional.

4, can be set in a separate each channel is effective.

5, linear input can be defined each of zero, full value and decimal digits.

Each channel 6, support on the lower limit alarm value respectively independent set and alarm indicator.

7, upper and lower unified relay output or every 4 road sharing a relay output.

Eight, can choose the combination of the four relay distribution.

9, can see the average, average can be a type of control.

10 and alarm output can be reset values (including sound and light alarm output).

11, which can realize checking zui big value, zui small value, average and instantaneous value or analog output, respectively, at the same time.

12, according to the operation function has three set menu B, C, D, where D convenient menu.

13, can provide multiple host, host, host form of asynchronous serial communication interface RS485.Communication data validation in accordance with CRC - 16 U.S. data communication standard, high reliable cyclic, barcode check.

Four, the technical parameters:

1, the basic error: 0.2% FS + 1 word;

2, bian: 1/20000, 14 A/D converter;

3, display way: double row four LED digital tube, display on the measured values, discharge according to the channel number;

4, sampling period: 0.5 S;

5, alarm output: (1) 1-64 channels on the lower limit alarm, AC220V / 3 a relay contact output capacity;

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 - isolation two-way communication by RS485 serial/RS422 / RS232 / Modem;

8, baud rate - 300 ~ 9600 BPS internal set freely;

9, electricity source, switching power supply of 85 ~ 265 vac power consumption below 4 w.

Five, the, instrument installation:

1. The instrument installation

1.1 meter before installation should check instrument model, index number, measurement range and sensor.

1.2 meter horizontal and vertical two types respectively, and the horizontal type torque type, horizontal type square and upright rectangle and several vertical square, etc.

2. The hole size

2.1 type 152 x 76 mm (a)

2.2 vertical 76 x 152 mm (b)

92 x 92 mm (c) 2.3 square

Six, selection table:

Note: additional optional a variety of functions, its serial number add note when you order it, 4, 5, 6 can only choose a kind of additive and its function.

After-sales service commitment:

1, wei tt&c display in my company sold products appear quality problem, within twelve months for free maintenance.

2, the warranty period, any quality problems such as the products of our company, my company is responsible for free repair or replacement.

3, the warranty period, such as user improper use, damaged products, my company is responsible for the maintenance, charge damage parts cost.

4, after the warranty period appear quality problem, my company is responsible for the maintenance, charge damage parts cost.

5, such as user need to my company site services, to users in the province I company service personnel to reach the site within 12 hours, fujian association of foreign languages and user reach the site within 48 hours.
