BLASI – motor brake relay
The BLASI motor brake relay is an essential electromagnetic switching component in BLASI automatic revolving door systems. This heavy-duty relay instantly activates DC injection braking upon emergency stops or cycle completion, eliminating motor coasting and ensuring precise door positioning. Rated for continuous 24VDC coil operation with 10A+ contacts, it coordinates with TA-4 logic boards to deliver rapid deceleration while protecting passengers from unexpected movement. Sealed construction withstands high-traffic commercial environments, maintaining reliable braking performance essential for safety compliance and mechanical longevity.
Product Details
The BLASI motor brake relay provides critical fail-safe braking control for automatic revolving door drive systems, instantly switching 3-phase motor windings from AC drive power to rectified DC braking current upon safety trigger activation. Integrated with TA-4 logic board sequencing, the relay executes millisecond response emergency stops while confirming motor standstill before re-energization authorization. Heavy-duty contacts rated for millions of operations handle continuous high-traffic cycling without degradation.
Arc suppression circuitry eliminates electrical wear while safety interlocks prevent premature power restoration during active braking phases. The industrial-grade enclosure resists dust infiltration, vibration stress, and temperature extremes typical of entrance applications. Essential for regulatory compliance and injury prevention, the motor brake relay maintains certified stopping distances and response times required for commercial certification.
