With the CPM1A or CPM2A, up to three Expansion Units or Expansion I/O Units
can be connected to the CPU Unit. One, two, or three of these Units can be
CPM1A-TS001 or CPM1A-TS101 Temperature Sensor Units. If a CPM1A-
TS002 or CPM1A-TS102 Temperature Sensor Unit is connected to the CPU
Unit, then only one other Expansion Unit or Expansion I/O Unit can be con-
nected. The other Unit can be a CPM1A-TS001/TS101 Temperature Sensor
Unit.
The CPM1A-TS001/TS101 Temperature Sensor Units each provide 2 input
points and the CPM1A-TS002/TS102 Temperature Sensor Units each provide 4
input points, meaning up to 6 temperature input points can be used on one
CPM1A or CPM2A PC. The inputs can be from thermocouples or platinum resis-
tance thermometers.
Up to 3 Units, including Expansion I/O Units and other Expansion
Units. (Only 2 Units if CPM1A-TS002/TS102 is used.)

Note 1. If only the CPM1A-TS001 and CPM1A-TS101 are connected, then up to 3
Units including Expansion I/O Units and other Expansion Units can be con-
nected. If the CPM1A-TS002 or CPM1A-TS102 is connected, then only one
other Expansion I/O Unit or Expansion Unit can be connected. The CPM1A-
TS001 or CPM1A-TS101 may be the other Unit, but another CPM1A-TS002
or CPM1A-TS102 cannot be connected.
