DO820: Digital Output
The DO820 is the Digital Output covered on this page. The attribute that decides whether it fits the existing installation without modification is 0.23 kg.
The reason to specify this exact variant is digital output. On a rack I/O module the configuration that matters is the one that decides whether the unit drops into the existing slot and speaks the existing signal. digital output sets channel count, voltage or current class and isolation behaviour — the three things that decide compatibility with the backplane, the field wiring and the rest of the I/O. Matching 0.23 kg against the rack rather than a generic datasheet avoids a module that installs but does not interface.
