Introdução do produto

The cleanroom door interlock controller is the logic hub behind a personnel or material airlock. It reads each door-position contact, determines whether another opening request is permitted and controls the corresponding electromagnetic lock or electric strike. A serviceable enclosure contains the power supply, protected output circuits, labeled terminals and programmable logic. Interface contacts can exchange status or release commands with access control, fire alarm and building-management systems without placing exposed electronics in the cleanroom doorway.

Características-chave

Dedicated inputs distinguish door-closed feedback, opening requests and emergency release commands.

Protected lock outputs support common fail-safe or fail-secure electric-lock arrangements.

Adjustable door-open and air-purge delays accommodate different airlock operating sequences.

Dry-contact interfaces allow coordinated signals with access control, fire alarm and BMS equipment.

Preocupações do produto do cliente

A controller must make door state visible, release locks safely and avoid ambiguous field wiring while remaining flexible enough for different airlock sequences.

A controller releases a second door because it cannot confirm that the first door is fully closed.Independent door-position inputs are evaluated before every release output is enabled.

Unlabeled field terminals make service faults difficult to isolate.Grouped and clearly identified inputs, lock outputs and auxiliary contacts simplify tracing and replacement.

A rigid sequence cannot accommodate purge time or emergency egress requirements.Configurable timers and dedicated emergency/fire inputs separate normal operating logic from safety release behavior.
