STEP Elevator Car Top Control PCB Board With CANBUS Comm For Door & Load Signal

Product Specification

STEP Elevator Car Top Control PCB Board With CANBUS Comm For Door & Load Signal IO Control Spare Part SM.02H-C

• The SM.02H-C is an original car top control PCB board designed for STEP elevator control systems, serving as the core IO communication node between the main controller and car top components to coordinate door operation, load detection and safety circuit signals.
• It adopts high-speed CANBUS serial communication technology, which greatly reduces the number of traveling cable cores and simplifies on-site wiring, ensuring stable and real-time data transmission between the car top and the machine room main control cabinet.
• It integrates rich input and output interfaces, supporting door position signal input, light curtain / safety edge signal, load weighing signals (light load / full load / overload), as well as door control output, arrival gong and car lighting control.

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.
