MCAFD4/8 Fieldbus Junction Box.MCAFD4 Active Fieldbus Distributor is suitable for the FF H1 and PROFIBUS PA fieldbus application.
MCAFD4 Active Fieldbus Distributor 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.
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
