AI820 3BSE008544R1 ABB Analog Input
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, hat 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. Features and benefits • 4 channels for -20...+20 mA, 0...20 mA, 4...20 mA, -10...+10 V,
0...10 V, 2...10 V, -5...+5 V, 0...5 V, 1...5 V d.c. bipolar
differential inputs • One group of 4 channels isolated from ground • 14 Bit resolution plus sign • Input shunt resistors protected to 30 V d.c. • The input withstand HART communication
