Overview / Features

This product is an expansion card that adds a thermocouple interface to the Raspberry Pi. Four channels of differential inputs are provided for one card.Linux device driver is supported with this product.

  • Compatible with various types of thermocouple inputs
    • This product is compatible with a wide range of thermocouple input types such as J(IEC60584-1), K(IEC60584-1), E(IEC60584-1), N(IEC60584-1), R(IEC60584-1), S(IEC60584-1), and T(IEC60584-1).
  • Cold junction compensation function within
    • As cold junction compensation is integrated in the product, there is no need to install a temperature sensor for cold junction compensation externally, and temperature can be measured simply by connecting a thermocouple.
  • Connectivity for up to 8 cards
    • Connect up to 8 expansion cards of the same series. Use the Board ID setting switch on the main body to identify connected expansion cards.
      * The Board ID setting switch cannot be set to 4 when using the CPI-RAS, CPI-PS10CM4, or CPI-MS10CM4.
  • Adaptable to a wide range of temperature between -20 and +60°C
    • The product is capable of operating in the temperature between -20 and + 60°C. It can be installed in the various environments.
  • No electrolytic capacitor
    • Without an electrolytic capacitor, which has a limited life, we are creating the product with a longer life.
  • Linux compatible driver software
    • Using the sensor input API-SSI(LNX) makes it possible to create applications of Linux.
