HCPL-4200 Overview
The HCPL-4200 optocoupler is designed to operate as a receiver in equipment using the 20 mA Current Loop. 20 mA current loop systems conventionally signal a logic high state by transmitting 20 mA of loop current (MARK), and signal a logic low state by allowing no more than a few milliamperes of loop current (SPACE). Optical coupling of the signal from the 20 mA current loop.
