AC30 series General Purpose I/O Option 
Specification 
Thermistor resistance range 
Resistance measurement 
accuracy 
Measurement supply voltage 
Motor temperature threshold 
Resistance threshold set by user. 
Default = 1kΩ. 
Motor temperature reset 
threshold 
Resistance based on temperature 
threshold. Default = 50% of trip 
threshold. 
Reinforced insulation between 
thermistor terminals and drive 
electronics. 
Important safety information: 
Insulation and routing of wiring to the GPIO thermistor terminals must be 
appropriately rated to ensure the correct degree of insulation to other user 
wiring.
