Overview
Optically Coupled 20 mA Current Loop Transmitter Technical Data HCPL-4100 Features • Guaranteed 20 mA Loop Parameters • Data Input Compatible with LSTTL, TTL and CMOS Logic • Guaranteed Performance over Temperature (0°C to 70°C) • Internal Shield for High Common Mode Rejection • 20 kBaud Data Rate at 400 Metres Line Length • Guaranteed On and Off Output Current Levels • Safety Approval UL Recognized -2500 V rms for 1 minute CSA Approved • Optically Coupled 20 mA Current Loop Receiver, HCPL-4200, Also Available Description The HCPL-4100 optocoupler is designed to operate as a transmitter 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 logic input to the 20 mA current loop breaks ground loops and provides very high immunity ...
