3-1-1 CPM1A-MAD01 Analog I/O Unit

CPM1(-V1)/CPM1A/CPM2A
CPU Unit
166
A maximum of 3 Expansion Units or Expansion I/O Units, including CPM1A-
MAD01 Analog I/O Units, can be connected to a CPM1, CPM1A (see note) or
CPM2A PC. One Analog I/O Unit allows 2 analog inputs and 1 analog output.
With the maximum of 3 Analog I/O Units connected, 6 analog inputs and 3 ana-
log outputs are possible.
The analog input range can be set to 0 to 10 VDC, 1 to 5 VDC, or 4 to 20 mA
with a resolution of 1/256.
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 0 to 10 VDC, 4 to 20 mA, or –10 to
10 VDC. The output has a resolution of 1/256 when the range is set to 0 to
10 VDC or 4 to 20 mA, or a resolution of 1/512 when set to –10 to 10 VDC.
A maximum of 3 Expansion Units or Expansion I/O Units can be connected.
CPM1A-20EDR1
Expansion I/O Unit
Note The CPM1-30CDR-j-V1 is the only CPM1 CPU Unit to which 3 Expansion
Units or Expansion I/O Units can be connected. Only one Expansion Unit or
Expansion I/O Unit can be connected to models without the "V1" suffix. Analog
Units cannot be connected to 10-point or 20-point CPM1A CPU Units. You must
use a 30-point or 40-point CPU Unit to connect to the CPM1A.
