Temperature Sensor Units Section 7-5
Part Names
Temperature Sensor Units:
CP1W-TS and CPM1A-TS
(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 CP-
series 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 CP-series Expansion Units or Expansion I/O Units.
Main Specifications
Note Accuracy for a K-type sensor at −100°C or less is ±4°C ±1 digit max.
