The TMC4TI2 cartridge features 2 analog input channels with 14-bit resolution.
The channel input types are:
oK thermocouple
oJ thermocouple
oR thermocouple
oS thermocouple
oB thermocouple
oE thermocouple
oT thermocouple
oN thermocouple
oPT100
oPT1000
oNI100
oNI1000
For further hardware information, refer to TMC4TI2.
Refer to Configuring Cartridges for a description of how to configure the inputs and outputs of the module.
Variables can be defined and named in the I/O Mapping tab. Additional information such as topological addressing is also provided in this tab.
