The AutroFieldBus driver EAU-341 is a communication protocol converter between the AutroSafe IFG panel

and the BSD-340 PowerLoop drivers and BSD-321 protocol converters.

The EAU- 341 provides a redundant field bus system with a ring loop topology.

The AutroSafe panels can have one AutroFieldBus connected, and each AutroFieldBus can host up to 31 bus units.

The AutroFieldBus has short-circuit detection/isolation technology which ensures that only one AutroFieldBus bus

unit will be lost in case of internal failure (short-circuit).

The ring loop topology ensures that no detectors/field units will be lost due to a single break or short

circuit of the AutroFieldBus cable. Furthermore, the EAU-341 provides optional AutroFieldBus earth fault detection.

The AutroFieldBus cable is normally 2-wire twisted pair category 5 copper cables, however,

fibre optic cable is possible by use of separate signal converters.

The AutroFieldBus uses the same guidelines as AUTROLON, in terms of cable lengths, fibre modem and boosters.
