LCD intelligent conditioner

Performance Overview:
Universal signal input, this product can input signals such as thermocouple, thermistor, current, voltage, and two-wire power supply and distribution through programming. The same product can have functions such as temperature transmitter, isolator, distributor, and millivolt transmitter, 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.
Technical features:
The intelligent function of input and output that can be set arbitrarily 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. Even in high-power frequency conversion control systems, it can still be reliably applied. It adopts digital calibration, zero free and full-scale potentiometers, automatic dynamic zero calibration, temperature drift automatic compensation, distribution power short circuit and input reverse connection protection, and meets the electromagnetic interference resistance requirements of the fourth category (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.
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.
Applicability:
Replacing traditional transmission instruments, its versatility makes this product highly applicable and flexible. This product 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.
