BM Series Analog Signal Isolator FAQs
4-20mA signal isolator is a signal amplifying instrument that isolates/amplifies/converts DC (analog) current and voltage signals and outputs proportionally.
It is used in the automation system of electric power, railway, petrochemical, metallurgy, chemical, food, storage and other industries.
A passive isolator is an instrument that isolates the input DC current signal and outputs it. The input/output of the transmitter is fully isolated and resistant to industrial field interference; it can work without external power supply.
The difference between an isolator and a switch is that a switch in the usual sense should be able to make and break current under working conditions (including overload conditions), while an isolator has no arc extinguishing capability.
