Isolated distributor is in the automatic control system for a variety of temperature transmitter, fl…
Description：
Products overview:
ZW - GLP seriesIsolation of distributorOffer at the scene of the transmitter isolation of dc power supply, and examined 4-20 ma current signal from the transmitter, after dealing with the isolation, interference resistance, etc.To the control system or other unit combination instrument output 4-20 ma dc current or voltage and other signals.
Second, the applications:
ZW - GLP seriesIsolation distributor is widely used in mechanical, electrical, power, petroleum, chemical, steel, sewage treatment in areas such as data acquisition, signal conversion, industrial measurement and control system, such as PLC, DCS, is used to improve and complement system simulation ∣ / O plugin function, increase the system applicability and reliability of field environment.
Three, 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, the 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.
