3-1-2 CPM1A-MAD11 and CPM2C-MAD11 Analog I/O Units
The following information applies to both the CPM1A-MAD11 and CPM2C-
MAD11 Analog I/O Units unless otherwise specified.
A maximum of 3 Expansion Units or Expansion I/O Units, including up to 3
CPM1A-MAD11 Analog I/O Units, can be connected to a CPM2A or CPM1A.
One Analog I/O Unit allows 2 analog inputs and 1 analog output. With the maxi-
mum of 3 Analog I/O Units connected, 6 analog inputs and 3 analog outputs are
possible.

•
The analog input range can be set to 0 to 5 VDC, 1 to 5 VDC, 0 to 10 VDC, –10
to 10 VDC, 0 to 20 mA, or 4 to 20 mA. The inputs have a resolution of 1/6000.
•
An open-circuit detection function can be used with the 1 to 5 VDC and 4 to
20 mA settings.
•
The analog output range can be set to 1 to 5 VDC, 0 to 10 VDC, –10 to 10 VDC,
0 to 20 mA, or 4 to 20 mA. The outputs have a resolution of 1/6000.
