Intelligent dual input display regulator

Products overview:

ZW - XMBA seriesDeveloped by using the, entrust integrated circuit manufacturers custom application-specific integrated circuit production, it not only collected all kinds of monitoring instrument in the automatic control system for most of the functionality, and integrates the CPU, I/D interface, RS485 and RS232 communication interface, EPROM and D/A conversion circuit, supplemented by eclecticism, elaborate, repeated debug software system using this instrument has the following characteristics.

1. ZW - XMBA series intelligent double input display apparatus hardware are greatly reduced, the system structure is relatively simple, the technology is improved significantly, did not fly line, no debug potentiometer, all the parameters setting, instrument calibration function are all through the keyboard performed by software.

2. ZW - XMBA series intelligent double input display apparatus can be set four alarm output, alarm method can reach more than 10.Can be arbitrarily assigned to a primary input or vice lose, also can be the difference in value assigned to the main input and vice or assigned to the main input and vice and values or assigned to the main input and vice input values.

3. ZW - XMBA series intelligent display apparatus with two inputs can be set to one of the switch to the other three switch monitor have a choice, and to realize intelligent sound and light alarm function with a quieter time.

4. ZW - XMBA series intelligent double input display apparatus optional add two or three road D/A output, can be arbitrarily assigned to A primary input or input use, analog output value of zero and full numerical range can be displayed in any setting.The output can be photoelectric isolation, provide 5 v and 24 two constant-voltage source output.

5. Any complex control, regulation, alarm, output, and other functions, can be the instrument has simple operation, set the pressure to be password protected, use it into a fool type instrument, the operator will not be able to modify the parameters of the locked.You set by the user at all levels of the four categories of one hundred kinds of anti-interference mode, can adapt to various environmental interference sources.

Second, the main functions:

1, the input signal for the input of various index number of thermocouple, heat resistance, all kinds of standard linear signal, (double input signal must be the same) or thermal resistance (Pt100) and linear signal (please specify when ordering.

2, display process measured in any setting range (1999 ~ 9999, 9999 ~ 1999, the decimal point 0 ~ 3 bits) or 0 ~ 99%.

3, double amount of input process instructions, two article simulated the triple according to instructions, etc.

4, double input display range can be set respectively.

5, the main input and vice input display value could add and subtract divide.

6, the main input after comparing with vice between input can control relay action.

After 7, break, break, break even the state of the output.

8, break, break, break after I used in the state of the relay type control, maintain function.

Three, technical parameters:

1, the accuracy of measurement: plus or minus 0.5% FS + 1 d±0.2%FS±1d；

2, alarm way: on the ceiling, floor, floor, poor poor last time, next time, double difference, OK, the absolute value method, etc.;

3, the analog output precision: plus or minus 0.2% FS.

4, analog output driven load impedance;

Current signal: 0 ~ 10 ma acuity 1.5 K Ω;4 ~ 20 ma 750 Ω p;

Voltage signal: 0 ~ 5 v, 1 ~ 5 v output impedance 1 Ω or less;

5, analog input impedance;

Current signal: 50 or less Ω;A voltage signal: 50 k or Ω;

6, the relay contacts capacity: AC220V, 3 a (impedance load)

7, the parameters of the set when the power is keeping time: 20 years or more;

8, dielectric strength: ac voltage 1500 v, 1 minute;

9, insulation impedance: more than 50 m Ω;

10, power supply: AC220V, 50 hz, 6 w or 24 v or less;

11, working environment requirement: temperature 0 ~ 50 ℃, relative humidity of 85% or less without corrosive gas, no vibration.

Four, according to instructions:

1. Double screen

(left) on the digital tube display the main input signal measurement

Discharge (right) deputy input measurement signals, the digital tube display or display operation value between the main input and vice

Article 2. The double screen + single simulation

(left) on the digital tube display the main input signal measurement

Discharge (right) deputy input measurement signals, the digital tube display or display operation value between the main input and vice

Simulation shows that the amount of input signal process %, the display of the switch between main channel and using the key implementation

Article 3. The single + double simulation

Digital tube display the main input signal or vice input measurement signal

According to switch between main channel and use the add button

The first article 36 line simulation in the form of percentage according to the main input signal measurement

The second article 36 line simulation to displayed in percentage of input signal measurement

Article 4. The double screen + double simulation

(left) on the digital tube display the main input signal measurement

Discharge (right), digital tube display vice input signal measured or operation value between the main input and vice

Article left simulation in the form of percentage according to the main input signal measurement

Article right analog signal measured at displayed in percentage of input

5. Light

A lamp or J1 lamp, SP1 is alarm indicator lights

E light or J2 light, is SP2 alarm indicator lights

Lamp or J3 lamp, B is SP3 alarm indicator lights

C lights or J4 lights, is SP4 alarm indicator

Five, the selection table:
