The BLASI NUM 400 safety stop module is a dedicated emergency shutdown controller for automatic revolving door systems. This compact safety relay module monitors emergency stop buttons, safety edges, and light curtains, instantly cutting power to motors and activating brakes upon hazard detection. Featuring dual-channel redundancy, positive-guided contacts, and fault monitoring, it ensures Category 3 safety compliance. Direct integration with TA-4 logic boards and Service-IBS diagnostics provides reliable fail-safe operation essential for high-traffic commercial entrances requiring certified emergency response capability.
Product Details
The BLASI NUM 400 safety stop module delivers certified emergency shutdown functionality through redundant safety relay circuits that immediately de-energize drive motors and engage electromagnetic brakes upon activation of any emergency input. Continuously monitoring mushroom buttons, safety edges, photocells, and occupancy sensors, the module guarantees response times under 100ms while providing visual fault indication and error memory for service diagnostics.
Designed to SIL 3 / PLe safety standards, the dual-channel architecture prevents single-point failures while force-guided contacts eliminate dangerous weld failures common in standard relays. Seamless integration with TA-4 control systems and KDT-ESL safety edge controllers creates comprehensive hazard protection across entire door perimeter.
Robust industrial enclosure withstands Dubai’s extreme temperatures and dust while maintaining IP65 sealing. Field technicians access comprehensive diagnostic data through Service-IBS interface, enabling rapid verification of safety circuit integrity required for regulatory recertification. Essential for preventing entrapment injuries in hotels, hospitals, offices, and public facilities where immediate emergency stopping prevents serious accidents during peak occupancy periods.
