Page 3: Short Description
Short description 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 transparent at the bus, i.e. control of AUMA actuators via bus is identical to control via copper cables (RS-485). -
Page 4: Fo Connection
FO connection FO connection Basic information Hazardous voltage! Risk of electric shock. Failure to observe this warning can result in death or serious injury. The connection must be carried out exclusively by suitably qualified personnel. Prior to opening: Disconnect both system and device from the mains. Observe basic information contained in this chapter. -

Page 8: Network Topologies
Network topologies Network topologies When connecting several field devices (actuators) in a network, the structure is called network topology. AUMA offers different network topologies. Line topology Figure 7: Structure for line topology Max. FO cable range in km (observe technical data!) FO T-coupler within electrical connection of ACExC 01.2... -
Page 9: Star Topology
Network topologies As soon as the actuator is switched off (motor voltage), the FO connection board of Case B this actuator is no longer available. As a consequence, communication with the (option) subsequent actuators is lost. To prevent this, the complete ACExC 01.2 can be externally supplied with 24 V DC. -
