Description of AI820:
The AI820 Analog Input Module has 4 differential, bipolar
current/voltage inputs. Each channel can be either a voltage or
current input. The current inputs can withstand an accidental
maximum normal mode 30 V d.c. connection. To protect the current
input circuit against dangerous input levels, that is, by
accidentally connecting a 24 V source, the resistor rating of the
250W current sense resistors is about 5 Watts. This is intended
only to temporarily protect one channel at a time.
The module distributes the external transmitter supply to each
channel. This adds a simple connection (with extended MTUs) to
distribute the supply to external 2 wire transmitters. There is no
current limiting on the transmitter power terminals.
All 4 channels are isolated from the ModuleBus in one group. Power
to the input stages is converted from the 24 V on the ModuleBus.
