Universal Input Connection
EasyIO FS series has non-isolated universal inputs.
Each channel comes with Programmable Gain Amplifiers which improve accuracy at lower range.
The universal input supports three mode of analog signal i.e. resistance, voltage and current transmitter
via hardware jumper and internal register settings:

UI as Digital Input
Voltage Free Contact
a)
Resistance – The working range of resistance is 500Ohm – 500KOhms. 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 – All Universal Inputs are capable of receiving high speed pulse. Minimum on time
pulse is 25ms and minimum off time is 25ms. Refer to image below.
