Performance profile:

Multi purpose signal input: through programmer setting, the product can input thermocouple, thermal resistance, current, voltage, two-wire system power supply and distribution signals. The same product can have 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 by operation and interference suppression, the isolated single or double linear current or voltage signals are transmitted to ensure the electrical isolation performance between the input, output and power supply.

Technical characteristics

The intelligent function of input and output can be set arbitrarily is the great technical advantage of the product. At the same time, the product has excellent performance in the suppression of high and low frequency interference signals. Even in the high-power frequency conversion control system, it can still be reliably applied. Digital adjustment, zero free and full potentiometer, automatic dynamic zero calibration, automatic temperature drift compensation are used internally The short-circuit and input reverse connection protection of distribution power supply shall meet the requirements of anti electromagnetic interference for products in class IV (harsh industrial site) environment specified in iec61000-4-4:1995. The application of this series of technologies ensures the stability and reliability of products scientifically.

The product also adopts the measurement and output value synchronous LCD digital display technology, which can observe the actual input and theoretical output value online, and realize the online fault self diagnosis. All the above technologies are at the international level.

Applicability

It can replace all kinds of traditional transmitting instruments, and its changeability makes this product have a wide range of applicability and flexibility. This product can be used with unit combination instrument, DCS, PLC and other systems. It is widely used in major projects of oil field, petrochemical, manufacturing, electric power, metallurgy and other industries.
