Part Names
Temperature Sensor Units
CPM1A-TS001/002/101/102
(1) Temperature Sensor Input Terminals
Used to connect temperature sensors such as thermocouples or plati-
num resistance thermometers.
(2) DIP Switch
Used to set the temperature unit (
°
C or
°
F) and the number of decimal
places used.
(3) Rotary Switch
Used to set the temperature input range. Make the setting according to
the specifications of the temperature sensors that are connected.
(4) Expansion I/O Connecting Cable
Connected to the expansion connector of a CP1H CPU Unit or a CPM1A
Expansion Unit or Expansion I/O Unit.The cable is included with the
Temperature Sensor Unit and cannot be removed.
Note Do not touch the cables during operation. Static electricity may
cause operating errors.
(5) Expansion Connector
Used for connecting CPM1A Expansion Units or Expansion I/O Units.
