SFGP isolator is an DFP isolator improved product of DDZ—Ⅲ electric unit combination instrument. It provides an isolated power supply for two-wire transmitter and also convert 4~20mA signal to isolated 1~5V/4~20mA signal. Input, output and power are isolated each other.
SFGP isolator adopts advanced circuit, effectively reduce the size of the instrument and simplify the instrument structure. There is a remarked improved than original DFP-type on accuracy, reliability, ability to adapt instrumentation to the environment and so on.
