MCAFD4/8/12 Active Fieldbus Distributor Product Overview
MCAFD series active fieldbus distributors are suitable for FF-H1 and PROFIBUS PA fieldbus applications. Field devices are connected to the system through the distributor in a trunk branch topology. Each MCAFD4/MCAFD8/MCAFD12 distributor has 4/8/12 branches, with built-in automatic bus terminals. LED status indication can quickly diagnose the short circuit status of main lines and branch lines, automatically isolate fault sections, and the distributor has multiple protection functions to ensure safe operation of the system.
