4.6 PowerLoop (BSD-340)
PowerLoop is a two-wire addressable loop used to interface point
Gas Detectors to the Maritime Gas Panel via the AutroFieldBus. Up to
15 devices may be connected in one addressable loop, depending on
the power consumption of the field devices and the cable topology.
PowerLoop can source a total of 100W (30VDC) to the devices
attached to the loop. It is possible to connect up to 15 field devices to
one PowerLoop: The number and placement of the detectors
connected to each loop has to be calculated during the design phase
as this depends on the power consumption of the connected units,
loop length and dimensions of the cable.
The diagram shows a selection of direct interfaced detectors and
4-20mA interface units connected to the BSD-340 PowerLoop driver.
A maximum of 31 PowerLoop modules can be connected to one
AutroSafe. A combination of BSD-340 modules can be connected in
one AutroFieldBus ring to the Maritime Gas Panel.
