Performance Overview
Input single or dual thermocouple and thermistor signals, transmit isolated single or dual linear current or voltage signals, and improve the electrical isolation performance between input, output, and power supply.

Technical Features
This product adopts advanced digital technology, has many advanced properties that traditional analog instruments do not have, and has excellent performance in the suppression of high and low frequency interference signals. It can still be reliably applied even in high-power variable frequency control systems. At the same time, the application of digital technology overcomes the disadvantage of poor linearity of traditional temperature transmitters. It uses digital calibration, zero free and full potentiometer, automatic dynamic calibration of zero, automatic compensation for temperature drift and many other advanced technologies internally, and meets the anti electromagnetic interference requirements of the fourth class (harsh industrial site) environment specified in IEC61000-4-4:1995. The application of this series of technologies ensures the stability and reliability of the product scientifically.
The above technologies are leading the international advanced level

applicability
It can be used in conjunction with unit combination instruments and DCS, PLC and other systems, and has a wide range of applications in major projects in industries such as oil fields, petrochemicals, manufacturing, power, metallurgy, etc.
