SI100 Series Voltage/current Isolator

SI100 voltage/current isolator isolates and transmits DC voltage or current signals, converting them into the required signals for other instruments. It can be used in conjunction with unit combination instruments, DCS, PLC and other systems to provide on-site instrument signal isolation, signal conversion, signal distribution, signal processing and other functions, thereby improving the anti-interference ability of the industrial production process automatic control system and ensuring the stability and reliability of the system.
