Product Overview
The NX-DA3203 expands NX control systems with four analog current outputs to drive valves, drives, and process devices requiring variable command signals. As an EtherCAT-integrated module, it supports deterministic networked control architectures. This unit is suitable for mixed-signal machines needing compact, maintainable analog output expansion.

FAQ for NX-DA3203
What devices can I control with analog output?
VFD speed reference (4-20mA), proportional valves, temperature controller setpoint, chart recorders, analog indicators, and any device accepting standard analog signals.
How do I configure current output?
Set via DIP switches on unit front. Each channel independently configurable. Current: connect to I+ and COM. Refer to unit manual for switch settings.
What's the output update rate?
1ms per channel. For 4 channels: 4ms total update time. Sufficient for most process control applications.
Can I use this for closed-loop control?
Yes, common application. Controller reads process variable (analog input), calculates PID, writes output (analog output) to control valve/VFD.
