BLASI – Logic board TA-4
The BLASI logic board TA-4 is the core processing and control PCB for BLASI automatic revolving door systems in the TA-4 series. This main logic board manages all operational functions including motor sequencing, safety sensor processing, emergency logic, and user interface coordination. Featuring advanced microcontroller architecture, the TA-4 logic board executes precise door movement algorithms, fault diagnostics, and safety interlocks essential for reliable commercial operation. Direct replacement restores full control functionality to TA-4 configured revolving doors.
Product Details
The BLASI logic board TA-4 serves as the central intelligence governing TA-4 series automatic revolving door operations. This sophisticated PCB integrates motor control outputs, safety input processing, emergency shutdown logic, and system diagnostics into a single reliable platform. The board continuously monitors door position encoders, safety sensors, and operational commands while generating precise drive signals for smooth acceleration, constant speed, and controlled deceleration through complete rotation cycles.
Designed for 24/7 commercial duty, the TA-4 logic board features comprehensive self-diagnostics, fault memory, and service mode access. It supports multiple safety configurations, speed profiles, and operational modes while maintaining compliance with international door safety standards. A malfunctioning board causes complete system shutdown, making it the most critical replacement component. Installing a genuine BLASI TA-4 board restores full operational capability, safety monitoring, and performance optimization to your revolving door system.
