Universal Input Connection
EasyIO FT series has non-isolated universal inputs. The universal input supports two type of analog signal
i.e. resistance and voltage via hardware jumper and internal register settings:
Universal Input
2 Channel
Resistance
3K - 50K (+/-10 Ohm)
Thermistor
10K Type 3, 10K Type 2, 20K,: All (+/-0.1 Deg-C)
UI as Digital Input
Voltage Free Contact
a)
Resistance – The working range of resistance is 3000 Ohm – 50k Ohm.
