BLDC Motor Control Board with Overcurrent Short Circuit Protection and RS485 Communication for Parking Barrier Gate System

This DC brushless barrier gate control board supports 1st to 5th generation parking barrier BLDC motors, delivering high-performance motor control for automatic parking barrier gates. It features hall effect limit switch technology that automatically recognizes open and close limit positions after power-on without manual calibration, ensuring high precision positioning and real-time motor speed detection for stable operation.

The integrated high-speed chip driver provides fast processing and large storage capacity, supporting 24V low voltage power supply and compatibility with DC24V, AC110V, and AC220V 50/60Hz global power inputs for safe, reliable operation.

Comprehensive multi-layer protection includes motor stall detection, over-current, over-voltage, under-voltage, short circuit protection, and built-in PTC thermistor overheat protection. Equipped with a 5-digit LED display and four-button keypad for onsite programming, parameter monitoring, and fast fault diagnosis.

Rich multi-channel digital inputs connect stop, open, and close signals, safety loop detectors, infrared photocells, and anti-collision radar. Multiple relay outputs work with flashing lights, warning lamps, and traffic light accessories. Built-in RS485 port supports remote control and intelligent parking system integration.

This mainboard supports 433MHz and 418MHz anti-copy remote control, obstacle auto-reverse, vehicle counting, anti-tailgating, fleet peak mode, and fire linkage functions. Modular layout simplifies installation and wiring.
