Description

The Electronic Component Model HCPL-4200-500E is an optocoupler designed specifically to operate as a receiver in equipment that uses the 20 mA Current Loop. In 20 mA current loop systems, a logic high state is signaled by transmitting 20 mA of loop current (MARK), while a logic low state is signaled by allowing no more than a few milliamperes of loop current (SPACE). The HCPL-4200 optocoupler is ideal for applications that require isolation between the transmitter and receiver.
