Industrial controllers and data acquisition equipment frequently require an isolated voltage-to-current loop converter in environments where high common mode noise exist and protection of equipment ...
A 4 to 20 mA loop current is a popular terminology with Instrumentation/Electronics engineers in process industries. Field transmitters like pressure,temperature,flow ...
This voltage-to-current converter delivers a variable 4mA to 20mA output (0V to 1V input) using only a positive power-supply rail. R S is selected so that the first term gives 16 mA for full-scale ...
Voltage-to-current converters that feed grounded loads are common in industrial measurement and control applications. The conventional "textbook" circuit uses both positive and negative supply rails.
