Overview

Intelligent isolation transmitter detailed introduction: Performance introduction Universal signal input, this product can input signals such as thermocouple, thermistor, current, voltage, two-wire power supply and distribution through programmer settings. The same product can have functions such as temperature transmitter, isolator, distributor, millivolt transmitter, etc., and the types and ranges of input and output can be set online. After processing such as computation and interference suppression, the input signal is transformed into isolated single or double linear current or voltage signals, ensuring electrical isolation performance between the input, output, and power supply. The intelligent function of input and output that can be freely set is the biggest technical advantage of this product. At the same time, this product has excellent performance in suppressing high and low frequency interference signals, and can still be reliably applied even in high-power variable frequency control systems. It adopts digital calibration, zero free and full range potentiometers, automatic dynamic zero calibration, temperature drift automatic compensation, distribution power short circuit and input reverse connection protection, and meets the requirements of Class IV (harsh industrial site) environment specified in IEC61000-4-4:1995 for electromagnetic interference resistance of the product. The application of this series of technologies ensures the stability and reliability of the product scientifically.

Product Details

This product also adopts synchronous LCD digital display technology for measurement and output values, which can observe actual input and theoretical output values online, and achieve online fault self diagnosis. The above technologies are leading the international advanced level.
