2.1 Performance Specifications
This section describes the performance specifications of temperature input modules.
Thermocouple input module
*1 Except for the conditions under noise influence.
*2 This conversion speed is the time required to store a measured temperature value into the buffer memory in sampling processing.
*3 No isolation is provided between the cold junction compensation channel and the programmable controller power supply.
*4 A count more than 50000 times causes Number of writes to offset/gain settings reach limit error (error code: 1080H).
