Frequently Asked Questions
What sensors can I connect to this analog input?
Voltage output: pressure transmitters (0-10V), temperature transmitters. Current loop: 4-20mA pressure, flow, level transmitters. Universal input suits most industrial sensors.
How do I wire 4-20mA current input?
Connect sensor + to input +, sensor - to input -. Unit provides 250Ω internal shunt. For external shunt or powered sensors, follow wiring diagram.
What's the resolution in engineering units?
For 0-10V: 10V/32000 = 0.31mV per count. For 4-20mA: 16mA/32000 = 0.5μA per count. Scale in controller to engineering units.
Can I use this for thermocouple input?
No, NX-AD3203 is for voltage/current only. For thermocouples, use NX-TC temperature input units with cold junction compensation.
