Application Procedure
The information provided here is based on a configuration with a single
Expansion I/O Board with 32 inputs/outputs and a single CPM2B-MAD63
Analog I/O Board connected to a CPU Board with 40 inputs/outputs. The ana-
log I/O specifications are as follows:
6-4-1
Board Assembly
The CPU Board, Expansion I/O Board, and Analog I/O Board are assembled
as shown in the following diagram.
For details on Board installation and connecting the Expansion Board connec-
tor, refer to SECTION 3 Installation and Wiring.

DIP Switch Settings
Note
1.
Always turn OFF the voltage/current input switch when using a voltage in-
put.
2.
Turn OFF the power before setting DIP switches to prevent malfunctions
caused by static electricity.
Voltage/Current Input Switch (DIP Switch 1)
When using either a current input of 4 to 20 mA (range code 010) or 0 to 20
mA (range code 011), turn ON (bottom) the pin of DIP switch 1 for the corre-
sponding input.
