C-DIAS Temperature Sensing Module
8 x Thermocouple inputs
8 x digital outputs+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.

  • Page 11: Wiring Guidelines

    C-DIAS TEMPERATURE SENSING MODULE CAI 888 Wiring Guidelines The signals recorded by the analog modules are very small, as compared to the digital signals. To ensure error-free operation, a careful wiring method must be followed. • The 0 V connection of the excitation voltage must be connected with the 0 V assembly point over the shortest route possible.
