Products overview:

ZW - XMBA seriesIntelligent four loop display apparatusFour is ZW - XMDA road signal input display mode.Drag it is its own research and development, 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 system, using the instrument has the following features:

1. ZW - XMBA series intelligent four loop display apparatus hardware are greatly reduced, the system structure is relatively simple, the technology is improved significantly, did not fly line, no potentiometer, all the parameters setting, instrument calibration function are all turn a completed by keyboard.

2. ZW - XMBA series intelligent four loop display apparatus can be set four five alarm output, alarm method can reach more than a dozen.Four relay can be arbitrarily allocated to all the way to four road input measurement control;Four road input can achieve unity upper and lower alarm;Can be set to one of the switch to the other three switch monitor have a choice, and to realize intelligent acousto-optic alarm with sound attenuation time.

3. ZW - XMBA series intelligent four loop display apparatus optional add 1 or 2 way or 3 way D/A, the analog output can achieve instant analog output instrument, instrument minimum analog output, instrument maximum average output, instrument simulation output.Also can be set arbitrary number 1 as a starting point for three consecutive road analog output.

4. ZW - XMBA series intelligent four loop display apparatus linear signal input can be defined per the zero value and full of all the way and the decimal digits, also can add prescribing shows small signal removal function.

Second, the technical parameters:

1. The accuracy of measurement: plus or minus 0.5% FS + 1 word

2. Adjust the control accuracy: a type: plus or minus 0.5% FS

3. The simulation precision analog output: plus or minus 0.5% FS, plus or minus 0.2% FS

4. The analog input impedance:

Current signal: 50 or less Ω;A voltage signal: 500 k or Ω;

Thermal resistance exterior resistance: 10 or more Ω;Thermocouple signal: 100 k Ω or higher

5. Analog output impedance:

Current signal: 0 ~ 10 ma acuity 1.5 K Ω;4 ~ 20 ma Ω 150 or higher

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

6. Warning: upper limit and lower limit, lower limit and upper limit and lower limit on poor, poor last time, next time, double difference, OK way and the way of absolute value.7. The relay contacts capacity: AC22V 3 a resistance (load)

After 8. Relay setting parameters remain time: 20 years or more

9. Power supply: AC220V, 50 hz, 6 w or 24 v or less

10. The work environment requirements: temperature: 0 ~ 50 ℃, relative humidity: 85% or less non-corrosive, no vibration.

Three, shows that:

1. 4 screen: PV1 screen first all the way the measured value of the input signal

P2v screen first all the way the measured value of the input signal

PV3 screen first all the way the measured value of the input signal

PV4 screen first all the way the measured value of the input signal

Note: if the instrument is 16 road inspection:

1 ~ 4 road measured values at the same time, according to the indicator H, D, F is not on

Measured value at the same time, according to 5 ~ 8 road lamp lights F, H and D the light not bright

Measured values at the same time, according to 9 ~ 12 road lamp lights D, H, F the light not bright

Measured value at the same time, according to 13 ~ 16 road lamp D, the F lights, H light not on

2. Single + four beams: single: display screen can be arbitrary display of the measured value of the input signal all the way, bring about key to switch.

Column 1: display all input in the form of percentage of measured signals;

Pillar 2: in the form of percentage according to the first two input signal measured;

Column 3: in the form of percentage according to the third road input signal measured;

Column 4: in the form of percentage according to the fourth road input signal measured;

Note: if the instrument is 16 road inspection: when the display shows the measured value of the 1 ~ 16 input signals;

1 ~ 4 percentage of measurement value of four beams at the same time, according to the indicator G, H is not on;

Percentage of measurement value of 5 ~ 8 road four beams at the same time, according to H lamp lights, G the light not bright;

Percentage of measurement value of 5 ~ 12 road four beams at the same time, according to the indicating lamp G lights, H the light not bright;

Percentage of measurement value of 13 ~ 16 road four beams at the same time, according to the indicating lamp G, H the light;

3. The indicator light

A lamp or J1 lamp: for SP1 point lights.

E light or J2 light: for SP2 point lights.

B the light or J3: for SP3 point lights.

C light or J4 light: for SP4 point lights.

Lamp of G, H lamp, lamp of D, the F lamp used to indicate a digital channel.

Four, selection table:
