Elevator PCB Board with Signal Centralized Acquisition CAN Bus Communication and Weighing Safety Logic Control Board MCTC-CTB-A

Elevator Inverter Main Board Monarch Elevator Parts, Elevator Car Top Communication Board Control Board MCTC-CTB-A

Signal centralized acquisition: 8 digital inputs (DI) via CN3 acquire switch signals from the car top safety circuit, door locks, limit switches, full load/overload sensors, etc.; 1 analog input (AI, 0-10V) receives the weighing sensor signal, providing data for pre-torque compensation and improving starting comfort.
Load drive control: Standard 7 relay outputs (expandable to 9) drive the car door motor, lighting, fan, alarm device, etc., realizing logical control and state switching of car equipment.
CAN bus communication: Real-time interaction with the main control board (MCB) via CAN+/- for operating commands, status feedback, and fault information, adapting to the Monarch serial communication architecture, reducing shaft wiring, and improving signal reliability.

Weighing and Safety Logic: Processes weighing signals to implement pre-torque compensation and full load/overload protection; interlocks with safety circuit contacts, immediately cutting off output and reporting faults in case of malfunction to ensure passenger safety.
Command and Display Interfacing: Connects to the car control panel (CCB) and hall call panel (HCB), forwarding floor registration and door open/close commands, and synchronously displaying operating status and fault codes to enhance the human-machine interaction experience.

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.
