This expansion I/O module adds a thermocouple interface to the CPU unit of the CONPROSYS nano series. Each module offers four channels of differential inputs.
Compatible with various types of thermocouple inputs
This module 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
As cold junction compensation is integrated in the module, there is no need to install a temperature sensor for cold junction compensation externally, and temperature can be measured simply by connecting a thermocouple.
LED indicator for status check
You can check the error status of the thermocouple, such as disconnected, not-connected, or sensor circuit trouble, with the LED indicator.
Easy installation and removal
This module can be installed in and removed from the CPU unit without any tools.
Adaptable to a wide temperature range between -20 and +60°C
The module operates with temperatures between -20 and + 60°C. It can be installed in various environments.
No electrolytic capacitor
Without an electrolytic capacitor, which has a limited life, we are creating a product with a long-life cycle.
