Provide isolated working power to the transmitter in the field, and at the same time detect the current / voltage signal in the loop. After transformation, the isolated current / voltage signal is output. The device has the advantages of fast response speed, low power consumption, and good temperature characteristics.
l It can be used in conjunction with modular instruments and DCS, PLC and other systems to provide signal isolation, signal conversion, signal distribution, and signal processing functions for field instruments, which enhances the anti-interference ability of the automatic control system in the industrial production process, ensuring the system's Stability and reliability.
