Study on antiRF interference measures for 4-20mA current output circuit

Abstract

Abstract: Abstract:The 4-20mA current output circuit is commonly used in industrial control field. Aiming at the radio frequency interference (RFI) on the 4-20mA current output circuit, by means of experiment and test, the studied data and solution for improving antiRFI ability of the 4-20mA current output circuit were given. The improvement measures were applied in distributed control system, and the system operates well.
