1. 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.
2. Feature
Short-circuit, overload protection for main line and branch line
Suitable for FOUNDATION Fieldbus H1 and PROFIBUS PA
LED indicator fault diagnosis
Automatic bus terminal
Reverse connection protection
Automatic isolating fault port
Protection class IP65

5.3 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.
