C-DIAS Temperature Sensing Module
CAI 888
8 x Thermocouple inputs
8 x digital 24 V
This analog input module is used for the recording of
temperatures.
The following thermocouple inputs can be connected:
Fe-CuNi (Type J) ... 0 – 600 °C
NiCr-Ni (Type K) ... 0 – 800 °C
FeCu-Ni (Type L) … 0 – 600 °C
In addition, 8 digital +24 V outputs (positive switching) are
available. The supply voltage is monitored for under voltage.
