KC868-A4S Analog Inputs

[admin]

1. Because not all inputs have a linear relationship with the output voltage. We divided it into three intervals using different coefficients. You can also calibrate your input channels according to the actual situation

2. i suggest you use a "NTC 10K to 0-5v output converter" module, it's very cheaper, easy find by aliexpress or other online store. just need convert NTC signal to DC 0-5v output, then you can connect to board's analog input ports.
