Product Overview
The Omron NX-AD2203 is an analog input unit from the NX Series I/O system, designed to interface analog sensors and transducers with NX Series controllers. This module provides 3 channels of analog input with 16-bit resolution, supporting both voltage and current input signals. The NX-AD2203 is ideal for monitoring process variables such as temperature, pressure, flow, and level in industrial applications. Its high resolution ensures accurate measurement, while the isolated inputs provide protection against electrical noise and ground loops. The module connects to the NX controller via EtherCAT, enabling fast data transfer and simple configuration through Sysmac Studio.

FAQ for NX-AD2203
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.
Can I configure each channel independently?
Yes, each channel independently configurable for voltage or current. Set in Sysmac Studio.
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.
Do I need external power for 4-20mA sensors?
No, unit provides 24VDC supply for 2-wire transmitters. Connect sensor + to unit's 24V+, sensor - to input +.
