FAQ

Q: Can this module drive multiple control valves simultaneously?
A: Each channel is isolated and supports 4–20 mA output. Up to four independent valves or actuators can be driven directly, depending on load requirements.

Q: How does NFTA4S‑00 differ from similar STARDOM modules?
A: Compared to standard analog output modules, NFTA4S‑00 provides full channel isolation and higher precision output, optimized for pressure clamp connections and industrial noise immunity.
