SIGMA Elevator Hoistway Communication PCB Board for Position Feedback & Door Status Signals Spare Part DHG-161

• The DHG-161 is an original hoistway communication PCB board designed for SIGMA (LG-OTIS) elevator systems, serving as the core data transmission node between the car assembly and the main control cabinet to realize real-time signal interaction across the elevator system.
• It is responsible for collecting and transmitting key operation signals including car position, door lock status, running direction and safety circuit state, ensuring the main controller can accurately grasp the real-time operation state of the elevator in the hoistway.
• Adopting differential signal transmission technology with strong anti-electromagnetic interference performance, it maintains stable low-latency data transmission even in the complex electrical environment of elevator hoistways, effectively reducing false emergency stop faults caused by communication errors.

Elevator PCB Board - FAQ

Q1: How do I identify the correct replacement elevator PCB board?
To identify a replacement elevator PCB board, check the original part number, hardware revision, board markings, and elevator controller model. Clear photos of both sides of the PCB can help distinguish different versions.

Q2: Can elevator PCB boards with similar part numbers be interchangeable?
Not necessarily. Elevator PCB boards with similar part numbers may differ in hardware revisions, firmware, connector layouts, or communication protocols. Compatibility must be verified against the existing elevator system.

Q3: Does a replacement elevator PCB board require programming?
Some replacement PCB boards require firmware configuration, parameter settings, or system-specific programming. Others may already contain the required software. The correct procedure depends on the PCB model and its role in the elevator control system.

Q4: Can a faulty elevator PCB board be replaced without changing the complete control system?
In some cases, an individual PCB can be replaced if the replacement is compatible with the existing controller, firmware, wiring, and connected components. A qualified technician should confirm the fault before deciding on replacement.

Q5: What information should I provide when sourcing a replacement elevator PCB board?
Please provide the original PCB part number, hardware revision, elevator model, clear board photos, and required quantity. SULAB can help review these details and check available replacement options.
