ABB DI821 Digital Input Module 3BSE008550R1

ABB DI821 Digital Input Module 3BSE008550R1

The DI821 Digital Input Module has 8 channels for 230 volt a.c./d.c. digital inputs.
The inputs are individually isolated. Channel 1 can be used as voltage supervisor for
channels 2 - 4, and channel 8 can be used for channels 5 - 7. 

ABB DI821 Digital Input Module 3BSE008550R1

If voltage supervision is disabled, channels 1 and 8 can be used as normal inputs. Each input channel
provides current limiting, EMC protection, input state LED indicator, noise filter
and optical isolation from the ModuleBus.
