Thermocouple Input Raspberry Pi Expansion Card 4ch
Model:
CPI-SSI-4C
Maker:
CONTEC Co., Ltd.
Features
- 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.
