The NI FP-DO-401 is a 16-channel sourcing discrete output module designed for industrial control applications requiring reliable digital switching. Each channel independently sources up to 1.5 A across a 5 to 30 VDC supply range, with low output impedance (0.3 Ω at 10–30 V, 2 Ω at 5–10 V) for minimal voltage drop. The module updates all channels at 20 kHz and draws 730 mW from the network module.
