Sigma Elevator Car Display Board with Red Digital Display Anti-Interference Circuit and Plug-and-Play Replacement

Sigma Elevator Car Display Board EiSEG‑205 Rev1 COP Cabin Floor Indicator PCB Red Digital Display

EiSEG‑205 Rev1 is original‑equivalent cabin display PCB specially for Sigma (LG‑Sigma) elevator car operation panel. It adopts bright red two‑digit digital tube display, stable signal communication with main elevator controller via dedicated plug‑in port. The PCB uses high‑quality electronic components, anti‑interference circuit layout, strong anti‑vibration performance to adapt long‑time running inside elevator car cabin. Precise mounting holes and original‑matching connectors support direct plug‑and‑play replacement without extra modification. Ideal spare component for elevator maintenance, retrofit and renovation projects when original display board fails, dim screen or no display fault occurs

Functions

1. Installed inside elevator car cabin, shows real‑time elevator floor number for passengers with high‑visibility red digital output.
2. Receives floor signal from elevator main control board, synchronizes running status data.
3. Reliable data transmission ensures clear floor indication, helps passengers confirm current position inside lift car.
4. Solves common faults such as no display, partial digit failure, dim light of old display PCB, restores normal cabin information display.

Elevator Display - FAQ

Q1: What types of displays are used in elevator systems?
Elevator systems use LED indicators, LCD screens, including TFT LCD displays, and other display technologies to show floor numbers, travel direction, and operating status.

Q2: Are elevator displays with the same screen size interchangeable?
Not necessarily. Displays with the same dimensions may differ in supply voltage, communication protocols, connector configurations, and control requirements. Compatibility must be verified before replacement.

Q3: What causes an elevator floor display to show incorrect information?
Possible causes include communication errors, controller configuration problems, wiring faults, or display module failure. The actual cause should be identified before replacement.

Q4: Can an elevator display be upgraded without replacing the control system?
In some systems, the display can be upgraded separately if the replacement supports the existing controller, communication protocol, and electrical requirements.

Q5: What information is required to order a replacement elevator display?
Please provide the original part number, display type, screen dimensions, supply voltage, communication interface, connector details, controller model, and clear photos for accurate matching.
