MCAFD8 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 eight branches.
Thereâ??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 most common temperature sensors are: motor sizes IEC180 225: thermal switch (e.g. Klixon) motor sizes IEC200 250 and larger: PTC or Pt100.See the firmware manual for more information on the motor thermal protection, andthe connection and use of the temperature sensors.Protection against short-circuit in the motor cableThe drive protects the motor cable and motor in a short-circuit situation when themotor cable is dimensioned according to the
To meet the European Union Directives, according to standard EN 60204-1, Safetyof Machinery, the disconnecting device must be one of the following types:â?¢ switch-disconnector of utilization category AC-23B (EN 60947-3)â?¢ disconnector that has an auxiliary contact that in all cases causes switchingdevices to break the load circuit before the opening of the main contacts of thedisconnector (EN 60947-3) circuit breaker suitable for isolation in accordance with EN 60947-2.
Only one permanent magnet motor can be connected to the inverter output.It is recommended to install a safety switch between the permanent magnet motorand the drive output. The switch is needed to isolate the motor during anymaintenance work on the drive.Planning the electrical installationSupply connectionDisconnecting deviceInstall a hand-operated input disconnecting device between the AC power sourceand the drive. The dis-connecting device must be of a type that can be locked to theopen position for installation and maintenance work.
