Description
Industrial LED Display Driver with RS485 Ethernet MQTT Voice and Relay Control
Industrial LED Display Driver with RS485 Ethernet MQTT Voice and Relay Control

The JUTAI NED200 Industrial LED Display Driver is a high-performance integrated control core tailored for industrial and commercial intelligent scenarios. It integrates multi-protocol communication (RS485/Ethernet/MQTT), LED display control, voice broadcast, and relay linkage, breaking the silo of single-function devices. With rugged industrial-grade design, rich expansion interfaces, and standardized operation logic, it serves as a reliable "central hub" for information transmission and multi-device collaboration—ideal for parking lots, factories, commercial complexes, scenic areas, and smart parks.

Key Functional Advantages
Multi-Protocol Communication for Universal Integration
  • Rich wired interfaces: Ethernet for LAN long-distance connection, RS485 for industrial on-site communication (100m range), RS232 for legacy device docking, and TTL for short-distance linkage
  • IoT & cloud compatibility: Supports MQTT protocol, enabling seamless integration into cloud management platforms and IoT systems for remote monitoring and control
  • Plug-and-play adaptation: Quickly connects to existing management systems (parking lots, workshops, malls) without modifying hardware architecture, reducing transformation costs
Industrial-Grade Relay & IO Linkage
  • High-load relay control: 2 industrial-grade relays can directly drive barriers, lights, equipment power supplies, and other devices, realizing automatic scenario linkage (e.g., door opening after QR code scanning)
  • IO status monitoring: Reads dry contact signals from sensors, buttons, or switches, triggering preset actions (e.g., voice alarms, relay cutoff) when abnormal events occur
  • Safe and stable: Relays feature isolated output, with overcurrent protection for IO interfaces, adapting to harsh industrial environments
Voice Broadcast & Interactive QR Code
  • High-capacity voice storage: 8MB memory supports up to 256 voice files, with ID call mode for flexible playback (sequential/immediate play) of welcome messages, safety alerts, or operation confirmations
  • Dual-mode QR code interaction: Full-screen QR code for long-distance scanning (e.g., parking payment), 3-line QR code with text description for short-distance interaction (e.g., scenic spot guides), facilitating "screen-person" quick connection
  • On-site voice updates: Supports on-site voice file upgrades via tools, adapting to dynamic scenario needs without replacing hardware
Flexible LED Display Control
  • 4-line independent management: Each line can display custom text, time, or notifications separately, meeting simultaneous transmission of multi-type information (e.g., navigation + promotions + time in malls)
  • Global language support: Built-in font library for over 100 languages, adapting to cross-regional and multi-ethnic application scenarios without additional font configuration
  • Expandable display interfaces: Compatible with HUB75/HUB08 LED modules, expandable to 4 HUB12 interfaces via expansion boards, covering most mainstream LED display specifications
Industrial-Grade Reliability & Easy Use
  • Extreme environment adaptation: Operates stably in -40°C ~ +85°C temperature range, suitable for outdoor or industrial workshops with large temperature fluctuations
  • Low operation threshold: All functions are controlled via standardized protocol commands, no complex programming required—technical teams can master it quickly
  • Minimal maintenance: No wearing parts; daily maintenance only requires checking communication lines and interfaces, reducing operation and maintenance workload
Application Scenarios
Industrial Workshops
Displays production data, safety guidelines, and equipment status in multi-language; IO interfaces detect equipment abnormalities, triggering voice alarms and cutting off power via relays to prevent failure expansion
Smart Parking Systems
Displays real-time parking availability and full-screen payment QR codes; relays control barriers to open automatically after payment, with voice broadcasts confirming "payment successful"
Commercial Complexes
4-line display for floor navigation, brand promotions, and real-time time; MQTT protocol enables remote content updates; QR codes link to coupons or membership registration
Smart Parks & Scenic Areas
Multi-language safety notices and 3-line QR codes for tour guides; visitors scan codes to register, triggering relays to open access control and play welcome voices
Access Control & Smart Buildings
Integrates with card readers via Wiegand interface; displays visitor information, plays welcome voices, and controls door access via relays, realizing intelligent entry management
Transportation Hubs
Provides multi-language schedules and directional guidance; Ethernet/MQTT supports remote content updates, ensuring real-time information transmission
Why Choose NED200 Industrial LED Display Driver?
  • All-in-One Integration: Combines communication, display control, voice broadcast, relay linkage, and QR code interaction, reducing system complexity and hardware costs
  • Industrial-Grade Durability: Wide temperature resistance, multiple protection mechanisms (reverse connection, overcurrent, ESD), ensuring 24/7 stable operation in harsh environments
  • Strong Expandability: Supports display interface expansion, voice file updates, and IO module addition, adapting to function upgrades without replacing the main device
  • Efficient Information Transmission: Multi-protocol + multi-language support enables fast information dissemination and cross-system collaboration, improving operational efficiency
