CF-DIDC8 has 8 DC24V input channels.
General Digital I/O (DIO) modules can be installed in the 6 slots directly to the right of the CPU module in the slots labeled “DIO”. The slot in which the DIO module is installed determines its I/O port number.
When a general DIO module is installed in position “+0” its ports will be assigned numbers 0 through 7. When installed in position “+30” its ports will be assigned numbers 30 through 37.
