Technical Specifications: Display Mode: Local status indicator and character display unit Operation Unit: Physical function operation buttons Communication Interface: D20 proprietary internal link for connecting D20C main controller Operating Power Supply: D20 series chassis internal power‑supply bus Operating Temperature: ‑10°C to +55°C Storage Temperature: ‑40°C to +85°C Relative Humidity: 5%‑95%, non‑condensing Mechanical Dimension: D20 series chassis front‑panel plug‑in unit Certifications: CE, power‑industry substation equipment EMC compliance
Functional Features: Local display of D20C controller running data, measurement value and fault alarm information. On‑site manual operation button for local mode control command issuing. LED status indicators for power, running, communication and fault alarm. Real‑time data interaction with D20C main controller via proprietary D.20 link. Used for on‑site commissioning, local monitoring and equipment status inspection.
Application Scenarios: D20 substation automation system local man‑machine interaction unit. Power‑substation control cabinet on‑site operation and status display. D20C controller system spare‑part replacement and maintenance project.
Structural Characteristics: Plug‑in front‑panel module matching D20 series standard chassis. Front‑panel layout includes display window, function operation buttons and LED indicator lamps. Rear‑side connector for D.20 link communication and power‑supply connection with D20C controller. Mechanical locking buckle for fixing on chassis front face.
Working Principle: D20C main controller transmits measurement data, equipment status and fault alarm information to D20C PANEL through D.20 proprietary link. Display unit presents real‑time information to field operator. Operation button input command is sent back to D20C main controller to complete local manual operation function. LED indicators synchronously show system power‑supply, running and communication fault status.
Installation Requirements: Insert D20C PANEL into corresponding front‑panel slot of D20 standard chassis. Ensure rear‑side connector is fully mated with D20C controller interface. Lock front‑panel mechanical buckle firmly after installation completion. Chassis grounding shall strictly follow power‑substation safety specification. Operating environment shall keep within temperature‑humidity range without condensation.
