Le RS-485 Isolator Click Board™ est un isolateur de communication RS485 et transporte l'ADM2682EBRIZ, un émetteur-récepteur RS-485 isolé du signal et de l'alimentation de 5 kV RMS.
Le RS-485 Isolator Click Board™ est conçu pour fonctionner sur une alimentation 3,3 V ou 5 V. Il communique avec le microcontrôleur cible via l'interface UART, avec des fonctionnalités supplémentaires fournies par les broches RST et CS sur la ligne MikroBUS.
The RS485 Isolator Click Board™ is a RS485 communication isolator, and carries the ADM2682E, a 5 kV rms signal and power isolated RS-485 transceiver, from Analog Devices. The click is designed to run on either 3.3V or 5V power supply. It communicates with the target microcontroller over UART interface, with additional functionality provided by the RST and CS pin on the mikroBUS™ line.
Use the click for isolating RS485 communication, and preventing voltage spikes from destroying sensitive equipment.
ADM2682EBRIZ Transceiver Features
The ADM2682EBRIZ is a fully integrated 5 kV rms signal and power isolated data transceiver with ±15 kV ESD protection that is suitable for high-speed communication on multipoint transmission lines. The ADM2682EBRIZ includes an integrated 5 kV rms isolated dc-to-dc power supply that eliminates the need for an external dc-to-dc isolation block.
