SFG-1104 signal power distribution unit is not only an improved DFG power distribution unit of DDZ-Ⅲ series products but also a SEG power distribution unit of DDZ-S series product. It can isolated transfer 1～5V or 4～20mA DC signal and widely used in industrial process control systems.

the isolators follow the DDZ-Ⅲ type instrument DFG model on structure and input/output signal.

However, as the machine circuit design uses high-performance solid functional modules, it is not only reduced weight, compact structure but also improve technical performance. SFG / DFGM-type signal isolators can isolating output 1～5V DC and 4～20mA DC signal so it also has the function to convert signal.
