Short description

AUMA actuator controls with FO connection are intended for use in optical fieldbus
networks.
The FO connection integrated in the electrical connection enables the conversion
from electrical RS-485 signals into optical signals and vice versa.
FO connection behaviour is passive at the bus, i.e. control of AUMA actuators is via
bus is made in the same way as for a connection via copper cables (RS-485).
Contrary to RS-485 based systems, different topologies are possible:
Line topology
Star topology
Redundant loop topology
Apart from the large distances, FO cables offer further advantages:
In environments with electromagnetic interference
Lightning arrester or overvoltage protection
Equipotential earth bonding and earthing
Galvanic separation of the actuator
Use of common cable trenches for power and signal cables
Prevention of interference emissions along the transmission line
This allows for customised solutions for various applications such as water/waste
water industries, tunnelling, power plants, thermal industry or telecontrol engineering.
