The Nabco MC-103-01B is a high-precision printed circuit board (PCB) designed as the primary control unit for Nabco/Nabco Entrances automatic sliding door systems. This intelligent controller manages the motor drive logic, door speed profiles, and safety sensor integration. Engineered for heavy-duty commercial use, the MC-103-01B ensures smooth, quiet, and reliable operation for high-traffic entrances. It features adjustable parameters for opening and closing speeds, braking force, and hold-open times, providing a customizable solution for modern architectural access requirements.

 

Technical Datasheet

Model Number: MC-103-01B Manufacturer: Nabco / Nabtesco Dimensions: 215mm x 110mm x 45mm Weight: 0.65 kg Country of Origin: Japan Input Voltage: 100V – 120V AC (Standard System Input) On-board Output: 12V / 24V DC for Sensors Compatible Drive Units: Nabco DS Series / GT Series Enclosure Compatibility: Aluminum Header Profiles

Application Fields

This PCB is the central control component for various automated pedestrian entrance systems, specifically:

• Retail storefronts and shopping mall entrances.
• Hospital and healthcare facility “clean room” automatic doors.
• Commercial office building main lobbies.
• Airport terminal boarding gates and security partitions.
• Public transportation hubs with heavy passenger flow.

 

Product Instructions

1. Mounting: Secure the PCB within the internal track/header of the automatic door system. Ensure the mounting standoffs are properly seated to prevent short-circuiting against the aluminum frame.
2. Wiring: Connect the motor harness, transformer leads, and safety sensors (photocells or microwave radars) to the designated terminal blocks. Follow the specific wiring diagram for the DS-series operator to avoid voltage mismatch.
3. Adjustment: Utilize the onboard potentiometers or digital switches to calibrate the door’s “creep speed” and “latching speed.” This ensures the door does not slam or rebound upon closing.
4. Testing: Perform a full “Learn Cycle” after installation so the board can map the door travel distance and weight load for optimized torque delivery.

 

Q&A – Frequently Asked Questions

Q: Is the MC-103-01B compatible with non-Nabco sensors? A: Yes, the board typically supports standard dry contact inputs from most infrared and microwave sensors, provided the power draw does not exceed the board’s auxiliary output capacity.

Q: What should I check if the door moves slowly and stops? A: First, check for mechanical obstructions in the track. If the track is clear, the MC-103-01B may be detecting an “over-current” situation, suggesting either a failing motor or a need to recalibrate the torque settings on the PCB.

Q: Can this board be used for swing doors? A: No, the MC-103-01B is specifically programmed with the acceleration and deceleration curves required for sliding door operators. Swing door applications require the Nabco GT-series swing controllers.
