4.9 AutroPoint Maritime Gas Detectors
The AutroPoint HC300PL (PowerLoop version) and AutroPoint HC-200
are diffusion-based, infrared combustible gas detectors that provides
continuous, fixed monitoring of flammable hydrocarbon gases from 0 to
100% Lower Explosive Limit. Standard device outputs include an
electrically isolated 4-20 mA signal with HART communication protocol,
and RS-485 serial communication. Serial communication protocols
supported include MODBUS and ASCII. An optional relay output board
with two programmable alarm relay outputs and one fault relay output is
available.
For further information, refer to data sheet 116-P-HC300PL/CGB (file
name hc300pl_cgb) and datasheet 116-P-HC200/CGB (file name
hc200_cgb).
4.10 PowerLoop 4-20 mA Input Unit BN-342
4.10.1 Description
The PowerLoop 4-20mA Input Unit BN-342 is a general purpose
PowerLoop interface designed for third party detectors connected to
the AutroSafe Maritime Gas System.
The PowerLoop is a two-wire power and signalling bus connected in
ring topology and is galvanically isolated from the rest of the system.
The unit communicates with AutroSafe using the PowerLoop protocol.
The unit has a 4-20mA input galvanically isolated from the
PowerLoop.
For further information, refer to data sheets.
