Fieldbus Junction Box

Brand : Microcyber

Product origin : China Shenyang

Product Overview

MCAFD4 Active Fieldbus Distributor is suitable for the FF H1 and PROFIBUS PA fieldbus application. Through the distributor, field devices use the topology of the main - branch to connect the system. 

Each distributor has four branches. There’s built-in automatic bus terminal. LED status indicator can rapidly diagnosis main line and branch line short circuit state, isolate the fault section automatically. Multiple protection function of the distributor can ensure the safe operation of the system.
