Overview
The Hanyoung Nux DX2-KMWNR is a panel-mount digital temperature controller engineered for industrial automation and process heating applications. This compact 48×96 mm unit combines K-thermocouple measurement with proportional-integral-derivative (PID) control, delivering precise temperature regulation through dual relay outputs. The DX2-KMWNR supports both direct and reverse action control modes, making it suitable for heating, cooling, or dual-loop setups in manufacturing, packaging, and chemical processing environments.
Key Features
- PID Auto-Tuning: Automatically optimizes proportional, integral, and derivative parameters for stable, responsive control without manual configuration.
- Dual Alarm Outputs: Independent high and low temperature alarm relays with independent set points for critical process protection.
- Control Loop Break Alarm (LBA): Detects sensor failures or control loop disconnection to prevent unsafe operation.
- Reverse & Direct Action Modes: Selectable internally; heating control (reverse) or cooling control (direct) per application.
- Compact Panel Form Factor: 48×96 mm DIN-style enclosure fits standard control panels; 100 mm depth behind panel.
- Wide Supply Range: 100–240 VAC 50/60 Hz operation; low power draw (approximately 4.5 VA at 220 V).

Replaces / Drop-In Replacement For
Verify compatibility with your system integrator before ordering. The DX2-KMWNR is part of the Hanyoung Nux DX2 series; similar models in this lineup (such as DX2-KCWNR, DX2-PMWNR, DX2-KSWNR) may be interchangeable depending on input type (K-thermocouple vs. Pt-RTD) and output configuration requirements.
Works With
- K-Type thermocouple signal conditioning (no external module required)
- Heating element relays, contactor coils, and SSR (solid-state relay) trigger circuits
- Dual-relay alarm logic integration in legacy and modern control panels
- Panel-mounted monitoring and manual override systems
