Product Details
Description:

Products overview:
ZW - that GLX seriesHas a great versatility and ease of use, can replace the traditional isolation of various instruments.The category of input and output signal and channel model can be set up the instrument type, range of input and output signal through hand operator support field calibration, it greatly enhances the usability of the product.Input signal after anti-interference, operations such as processing variable output isolated single path, double line current or voltage signal.
Second, the working principle:
ZW - that GLX seriesSignal isolator are signal transmitter or together through modulation conversion semiconductor devices, and then through the light or magnetic induction device to convert the isolation, then back to before the isolation signal demodulation transformation, at the same time to isolate their isolation signal of power supply, ensure that after the transformation of signal, power supply, to the absolute independence, between the single or dual is the input current or voltage signal, single or double line analog output isolation of current or voltage signal, and improve electrical isolation between input, output, power performance.
Applications:
ZW - that GLX seriesSignal isolator in addition to the general function, can also support to logical processing of signal, the state set up alarm output, chip for the function of the isolator has brought the revolutionary progress, broaden the application range of the isolator.With unit combination instrument and DCS, PLC systems, such as in oil field, electric power, metallurgy, petrochemical, manufacture industry has been widely applied in major projects.
Four, the main features:
1, the single-chip microcomputer unique and powerful software function and isolator's own excellent hardware electrical properties for the stability and reliability of the product provides a solid guarantee.
2, intelligent isolator can use communication protocol USES the means of communication and hand connection, online observation input, the output value.
3, without using zero and full of external potentiometer to digital signal automatic/manual adjustments.At the same time can be automatically compensate to the input signal.
4, intelligent isolator of the input signal is the high and low frequency interference signal provides the software on the suppression and processing.Even in high power frequency conversion control system is also capable of reliable operation.
5, single or double input for the linear current or voltage signal of the road.
6, analog output isolation of single, double current or voltage signal and the input, output, and provide a good electrical isolation between the power.
Five, the technical parameters:
1, the system transmission accuracy: + / - 0.2% x f. S.
2, temperature drift: 0.005% f. S / ℃ or less;
3, working temperature: industrial standards - 10 ~ + 55 ℃;
4, input impedance: current: 100 Ω;Voltage: 500 k Ω;
5, allowing external load impedance output current: 4-20 ma output 0 ~ 500 Ω;0 to 10 0 ~ 1 k Ω, the output of the ma need more load capacity when ordering, please;
6, electromagnetic compatibility: meet IEC61000-4 - and in 95 the fourth category specified in (a) bad industrial site environment on the product's resistance to electromagnetic interference requirements;
7, input/output/power/communication/double insulation strength: 1500 v or higher. The ac;
8, storage and transportation environment temperature: - 40 ~ + 80 ℃;
9, relative humidity: 10-90% RH (40 ℃);
10, power supply, communication: 95 ~ 265 v AC;
11, dc: DC12V ~ 32 v (reverse connect protection);
12, the input power: 0.9 ~ 1.8 W (related to the model, see the appendix to this manual calculation method about the input power);
13, communication interface, RS232 or RS485, MODBUS protocol software (optional).
14, overall dimensions: width * deep high: 22.5 * 100 * 115 mm;
15, net weight: 20 g to 140 g +.
Six, notable matters of installation:
1.Should read the instructions before use.
2.Used as signal isolation, should be the input string into the loop circuit, the output termination sampling circuit.
3.Used as isolation distribution, should be in series with the input power supply circuit, the output termination transmitter.
4.If he does not work properly should be check the wiring is correct, pay attention to the power supply has a common polarity anyway.
Seven, selection table:
