The Hanyoung Nux NX4 Controller delivers high-accuracy PID regulation, advanced fuzzy logic temperature control, and multi-input versatility engineered for industrial ovens, plastic extrusion skids, packaging heat-sealers, and environmental chambers.

High-Precision Thermal Control with the Hanyoung Nux NX4 Controller

Engineered for stability in critical industrial thermal loops, the Hanyoung Nux NX4 Controller combines digital PID auto-tuning with integrated fuzzy logic compensation. This control architecture effectively suppresses overshoot during initial machine warmup and eliminates thermal hunting during sudden process load disturbances. Its high-contrast dual 4-digit LED display simultaneously presents real-time process values (PV) and programmed setpoints (SV) with high optical clarity from broad viewing angles.

The instrument provides universal sensor selection, enabling technicians to configure thermocouples, resistance temperature detectors (Pt100 RTD), or analog DC voltage/current signals directly via front parameter keys. Equipped with versatile output configurations—including electromechanical relay, solid-state relay (SSR) voltage pulse, and linear 4–20 mA current transmission—the unit interfaces seamlessly with SCR power controllers, contactors, and automated supervisory systems.

Frequently Asked Questions

What is the benefit of fuzzy logic enhancement in the Hanyoung Nux NX4 Controller?
Traditional PID controllers can suffer from overshoot when warming up from ambient conditions. Fuzzy logic automatically calculates predictive adjustments during high thermal transition rates, preventing material scorching and improving setpoint stabilization speed.

Can the control output mode be modified in the field?
While models are ordered with specific primary output hardware (relay, SSR drive, or 4–20 mA), the internal software parameters allow full adjustment of cycle times, proportional bands, and heating/cooling action directions directly through the front keypad.

Does the unit feature multi-alarm capabilities?
Yes. The controller supports multiple auxiliary alarm relay outputs with configurable operating modes, including upper-limit, lower-limit, band alarm, and sensor burnout alarm notifications.
