You can connect cables of 0.25 mm
The use of this front connector results in no restrictions regarding the approvals of the module.
Alternatively, you can use the front connector 6ES7392-1AJ00-0AA0, but without the
increased accuracy.
Non-connected input channels
You must short-circuit activated and non-connected channels of the analog input module. This
way you ensure optimum interference immunity for the analog input module.
In addition, disable the non-connected channels using the parameter assignment dialog of HW
Config in order to shorten the cycle time of the module (measurement type: "Disabled")
Special feature of resistance measurement
Only one channel per channel group is required for the "resistance measurement" and "thermal
resistance measurement". The "2nd" channel of the group is used for the current injection (I
With the "1st" channel of the group is accessed , the measured value is obtained. The "2nd"
channel of the group is preset with the overflow value "7FFFH".
In the diagnostics, the 1st channel provides the actual status (based on parameter assignment)
in each case and the 2nd channel the status "error-free". A resistance measurement is not
possible in redundant use.
