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.
