Elevator Controller Board Kit | G+4 First-Come-First-Serve (FCFS)

The Elec Design Hub G+4 elevator logic board fabrication kit provides the entire electronic backbone for your elevator system—from the machine room motherboard to the premium Car Operating Panel (COP) display. Stop worrying about component compatibility or complex programming. This industrial-grade low-rise elevator logic circuit is designed using the powerful ESP32 microcontroller to suit exceptionally safe, low-rise vertical mobility.

Every single Elevator Controller Fabrication Kit is designed and engineered by an IIT Kharagpur alumnus with over 45 years of hands-on industrial electronics experience. It is ideal for heavy-duty freight elevators, goods lifts, and basic residential applications where sequential, chronological call processing is preferred.

What’s Included in the FCFS Elevator Controller Kit:

• 1 No. Master Motherboard + Display Driver: The highly reliable, opto-isolated core logic controller board.
• 5 Nos. Scrolling Dot Matrix LOP Cards: High-visibility hallway displays pre-configured for Ground through 4th floor.
• 1 No. Premium Nextion TFT Driver Card & Nextion Discovery NX4832F035: A modern, 3.5" full-color resistive touch display interface for the elevator cabin (COP). The display will be fully customized before delivery to display your corporate logo, boosting your company image. We will send you a pre-filled "Product Customization Request Form" via email upon purchase.
• 1 No. Heavy-Duty Open-Frame SMPS Card: Clean, isolated 12V / 3A DC output from a 230V AC single-phase input, engineered specifically to withstand the severe electrical noise of elevator shafts.

Technical Specifications & Architecture:

Core Processing & Intelligence

• Microcontroller: Dual-Core ESP32 Processor (Tensilica Xtensa LX6 @ 240MHz)
• System Capacity: 5 Stops maximum (Ground + 4 Floors)
• Routing Logic: First-Come-First-Serve (FCFS) processing hall and car calls in sequential chronological order.

Input / Output & Noise Immunity

• Input Protection: Heavy-duty PC817 Opto-Isolators on all logic inputs to completely block contactor inductive kickback.
• Signal Filtering: Strict 50ms software RC debounce filter across all floor sensors to eliminate EMI-induced "phantom" calls.
• Motor / VFD Interface: 4 Dedicated onboard output relays mapped for standard 2-Speed VFD control (High Speed, Low Speed, Motor Up, Motor Down).
• Door Operator: Dedicated Open/Close relay logic with configurable intelligent "Same-Floor" call resolution.

Safety & Emergency Protocols:

• Hardware Safety Chain: Dedicated physical SAFETY_CHAIN_PIN instantly locks out motor drive engagement if the safety loop or door landing lock is compromised.
• Anti-Burnout Timeout: Hardcoded 25-second motor timeout fault limit. Cuts all drive power if the cabin fails to reach the next floor sensor, preventing motor burnout during mechanical jams.
• Fireman Mode: Dedicated emergency input forces cabin directly to Ground floor, clears all memory call arrays, and parks safely with doors open.
• Maintenance Mode: Manual toggle switch bypasses passenger calls, allowing safe jogging of the cabin via dedicated UP/DN hardware buttons.

Display & Communication Metrics:

• Serial Output: Live asynchronous UART data streaming <Floor, Direction, Mode Operating> for seamless Nextion TFT COP integration.
• Legacy Parallel Support: Integrated standard 7-Segment/BCD bit pattern outputs for legacy scrolling dot-matrix Landing Operation Panels (LOP).
