| Communication |
A digital network that is used between a main module and its expansion modules is implemented on the local bus, Communication does not link main modules
|
|---|---|
| Power |
Passes power from each main module (1444-DYN04-01RA) to its expansion modules, Power is not passed between main modules, When redundant power supplies are connected to a main module, only the voted power source is distributed to its expansion modules.
|
