SFP-2104 power distribution unit can offer an isolated power for on-site transmitter. It can convert DC 4～20mA current signal which from transmitter to isolated 1～5V DC voltage signal to realize the dual-isolating between transmitter, second instrument and power.
Feature：
The power distribution unit is equip with general type, or explosion-proof type transmitter
if it is used in intrinsically safe explosion-proof occasions, it must add safety barrier.
Because the circuit uses the signal isolation techniques so that it can effectively restrict common mode interference。
The circuit structure is simple
