A communication protocol converter between the AutroSafe IFG panel and the BSD-340 PowerLoop drivers. Provides a redundant field bus system with a ring loop topology.
The AutroFieldBus driver EAU-340 is a communication protocol converter between the AutroSafe IFG panel and the BSD-340 PowerLoop drivers. The EAU-340 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 BSD-340 PowerLoop driver 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.
The AutroFieldBus cable is normally 2-wire twisted pair category 5 copper cable, 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. The EAU-340 is to be mounted in a subrack in the same rack as AutroSafe.
