Combination Analog Configuration Requirements
The F2-4AD2DA Analog module requires 16 discrete input and 16 discrete output points.
The module can be installed in any slot of a DL205 system, except when the DL230 CPU
is used. The available power budget may also be a limiting factors. Check the DL205 PLC
User Manual for the particular model of CPU and I/O base being used for more information
regarding power budget and number of local, local expansion or remote I/O points.
