性能简介： Introduction to the performance of LCD intelligent conditioner :
Universal signal input, the product can be set to input thermocouple, thermal resistance, current, voltage, two-wire power supply and distribution signals through the setting of the programmer. The same product can be equipped with temperature transmitter, isolator, distributor, millivolt Transmitter and other functions, and the type and range of input and output can be set online. After the input signal is processed, interference suppression and other processing, it will transmit and output the isolated single or dual line current or voltage signal, and ensure the electrical isolation performance between the input, output and power supply.
Technical Features The intelligent function of input and output can be set arbitrarily is the biggest technical advantage of this product. At the same time, this product has excellent performance in the suppression of high and low frequency interference signals, and it can still be reliable even in high-power variable frequency control systems. Application, internally adopts digital adjustment, zero-free and full-scale potentiometers, automatic dynamic calibration zero, automatic temperature drift compensation, short-circuit of power distribution and reverse input protection, and meets the requirements of IEC61000-4-4: 1995. The four types (harsh industrial scenes) of the environment require anti-electromagnetic interference to the product. The application of this series of technology makes the product's stability and reliability scientifically guaranteed.
This product also adopts the measurement and output value synchronous liquid crystal digital display technology, which can observe the actual input and theoretical output value online. At the same time, it realizes online fault self-diagnosis. The above technologies are leading the international advanced level.
Applicability replaces traditional various transmission instruments, and its adaptability makes this product have a wide range of applicability and flexibility. This product can be used in combination with unit combination meters and DCS, PLC and other systems, and has been widely used in major projects in the oilfield, petrochemical, manufacturing, power, metallurgy and other industries.
