EasyIO FC-20 has twelve non-isolated universal inputs. The universal input supports three type of analog
signal i.e. resistance, voltage and current transmitter via hardware jumper and internal register settings:
a) Resistance – The working range of resistance is 0 – 300K Ohms. If the input is configured as
Thermistor type, the system provides 8 customizable temperature lookup tables for resistance to
temperature translation. The commonly used Thermistor like 10K, 10K with Shunt, 1K Balco and 1K
Platinum are all supported
b) Voltage – Two selection of working range 0 – 5V and 0 – 10V. The minimum input impedance of
voltage input is 1 Mega Ohm.
c) Current – Two selection of working ranges 0 – 20mA and 4 – 20mA. The current input impedance is
less than 25 Ohm.
d) Pulse Input – Only UI1, UI2, UI3 and UI4 are capable of receiving high speed pulse. Minimum on time
