Section
I/O Allocation for CPM1/CPM1A/CPM2A PCs
314
Note
1. The values for the maximum number of I/O in the above table include I/O on
Expansion I/O Units.
2. When using a CPM1 CPU Unit other than the CPM1-30CDR-
-V1, one of
the following 20-point Expansion I/O Units can be connected to the PC:
•
CPM1-20EDR (relay outputs)
•
CPM1A-20EDRT (sinking transistor outputs)
•
CPM1A-20EDT1 (sourcing transistor outputs)
3. When using the CPM1-30CDR-
-V1, up to 3 CPM1/CPM1A Expansion I/O
Units or CPM1A-MAD01 Analog I/O Units can be connected to the PC.
