Liquid crystal intelligent conditioner

Products overview:
ZW series - TLAAs input thermocouple, heat resistance, current, voltage, two wire power supply, such as signal, the same product can have the temperature transmitter, isolator, distributor, millivolt transmitter, and other functions, and the types and range of input and output can be set up online.Input signal after operation, such as interference suppression processing, single or double line analog output isolation of current or voltage signal, and to ensure electrical isolation between the input, output, power performance.
ZW series - TLAType LCD intelligent control device also made the technique of synchronous measurement, the output value LCD digital display, can online observation of actual input and output value theory, at the same time realize the online fault diagnosis, the above technology has the international advanced level.
Applicable occasions:
ZW series - TLAType LCD intelligent control device to replace the traditional kinds of transmitting instrument, its variable by nature makes this product has a very extensive applicability and flexibility.This product can be with the 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.
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, 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.
