RD-500 5-Inch LED Display: Optical Sun-Visor Hood, Weatherproof Cabinet & Driver Visibility
High-Visibility Outdoor LED ArchitectureWeatherproof Powder-Coated Mild Steel / Aluminum with Sunhood Visor. Engineered for outdoor mounting in direct Iraqi sunlight.
- Heavy galvanized cold-rolled steel cabinet with electrostatic outdoor polyester powder coating.
- Integrated top sun visor hood shades the optical window from direct midday desert solar glare.
- Heavy-duty adjustable steel swivel brackets allow horizontal and vertical aiming towards truck driver eye-level.
IP65 sealed weatherproof cabinet designed for severe sandstorms and driving rain.
- High-impact tinted acrylic/polycarbonate faceplate with anti-reflective optical treatment.
- Gasket-sealed perimeter prevents airborne dust, desert sand, and water jets from entering the cabinet.
- Passive labyrinth thermal cooling vents prevent internal heat buildup without compromising dust sealing.
High-Luminance LED Digits & Distance Visibility
Super-bright 5-inch (125mm) red LED digits with auto-dimming night sensor; annunciators for Gross, Net, Tare, kg, and Stable reading.
RD-500 5-Inch LED Display: Serial Communications, Auto-Baud Detection & Current Loop Interfacing
Hardware Interface Map| RS-232 (RXD/GND) | Direct serial link from scale indicator cabin (Baud: 1200–19200 bps) |
| RS-485 (A+/B-) | 2-Wire balanced differential line for long distances: RS-232, RS-485, 20mA Current Loop (Auto-Baud 1200 - 19200 bps) |
| 20mA CURRENT LOOP | Active or passive current loop interface immune to plant electrical noise |
| MAINS POWER | Power supply: Operates directly from 220V AC or optional 12V/24V DC (Internal Switching Power Supply 100-240V AC 50/60Hz) |
| LOOP-OUT | Passive Loop-Through Serial Output allows daisy-chaining multiple displays |
- Auto-Baud Protocol Sensing: Microcontroller automatically detects and synchronizes with indicator baud rate and data string formats.
- Universal Indicator Support: Works seamlessly with SCA, KRONOS, Toledo, Rinstrum, Dini Argeo, and Avery indicator data protocols.
- Zero Display Latency: Zero Lag / Real-Time Refresh Rate mirrors indicator instantaneously.
- Surge Guard: Built-in Thermal Overload & Surge Protection protects communications boards.
RD-500 5-Inch LED Display: Regional Field Performance Across Iraq & Solar Radiation
COSQC Legal VerificationHigh ambient humidity and industrial emissions require UV-stabilized polycarbonate faceplates to prevent discoloration and yellowing over years of service.
Extreme midday sun (>100,000 lux) and temperatures over +50°C. High-brightness LEDs and sun-visor ensure driver readability without cabin disputes.
Freezing winter temperatures down to -20°C. Solid-state LED construction eliminates cold-weather start-up lag and digit freezing.
Iraqi Legal Metrology Auxiliary Display Standards
Functions as a legal auxiliary repeater display compliant with COSQC and OIML R76 regulations, providing transparent weight verification directly to truck drivers.
