4.3 PowerLoop Driver BSD-340
4.3.1 Description
The PowerLoop Driver BSD-340 functions as a protocol converter
between AutroFieldBus and PowerLoop.
It consists of a PowerLoop interface for power and communication,
and an AutroFieldBus interface towards an AutroFieldBus Driver
(EAU-341).
The PowerLoop is a two-wire bus capable of delivering 30VDC/ 100W
connected in ring topology and is galvanically isolated from the rest of
the system. The PowerLoop interfaces detectors and other loop units
including a 4-20mA interface.
The BSD-340/1 provides a service port female DSub 9-pin, which is
used for commissioning and maintenance.
The AutroFieldBus address is set by switches. The AutroFieldBus is
normally category 5 copper cable.
There are three versions:
• BSD-340/1 Rack mounted version
• BSD-340/2 Rail mounted version
• BSD-340Ex
For further information, refer to data sheets.
