ABB AO820 3BSE008546R1 Analog Output Module AO820 S800 Series I/O Module 4×1 ch
Description of AO820
The AO820 Analog Output Module has 4 bipolar analog output channels. The choice of current or voltage output is configurable for each channel. There are separate sets of terminals for voltage and current outputs, and it is up to the user to wire outputs properly. The only differences between current or voltage channel configuration is in software settings.
To supervise the communication to the A/D-converters the output data is read back and verified. The opencircuit diagnostics are read continuously as well. The process voltage supervision input give channel error signals if the voltage disappears.The error signal can be read via the ModuleBus.
