| | Number of Channel | [8 analog input modules]: 16 analog channels + 16 logic channels (standard)
[5 analog input modules + 3 logic input modules]: 10 analog channels + 64 logic channels
(standard 16 channels + 48 channels in logic input modules)
* For analog modules, channels are insulated vs. each other and vs. unit ground.
For logic modules and integrated standard logic channels, all channels use the unit ground. |
