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. The MCAFD8 active fieldbus distributor is suitable for FF-H1 and PROFIBUS PA fieldbus should be used to connect field equipment to the system in a main-branch topology through the distributor, each of which has eight branches, built-in automatic bus terminal, LED status the indicator can quickly diagnose the short circuit status of the main line and secondary line, automatically isolate the fault section, and ensure the safe operation of the system with multiple protection functions of the distributor.

Wiring of MCAFD4 Active Fieldbus Distributor
1. Connect bus through T1 & T2, T1 for bus input, T2 for bus ouput, and connect fieldbus devices by branch S1 to S4.
2. Open cover of active fieldbus distributor, and install the distributor to the flat surface or on the guide rail, to ensure 60 mm space connection on the rear left of and below the distributor.
3. Unscrew the electrical connector, run the fieldbus cable through the electrical connector gland, and twist the cable onto the corresponding terminal, to ensure correct polarity of the connection.
4. Close the active fieldbus distributor cover, tighten the fixing screw.
5. Use seal plug to seal unused cable entry gland, so as to ensure the IP65 protection class.
