Import Door Interlocking Terminal (Dit-800) — Buy in wholesale FOB from Supplier in India

The Door Interlocking Terminal DIT-800 is a control unit designed to manage the sequential operation of up to eight doors in secure environments such as clean rooms, laboratories, and high-security zones. It uses DOTL signals to coordinate lock relays and provides visual feedback via green and red LEDs, with audible alerts from a built-in buzzer. The system ensures only one door in a group can be unlocked at a time, preventing simultaneous access and maintaining environmental or security isolation. It supports both switch-based and switchless operation modes, allowing flexibility in user interface design without requiring physical buttons at each door.

The terminal operates on low-voltage control signals and includes digital outputs capable of driving up to four additional relays for auxiliary functions. Internal logic is programmable via serial communication, enabling custom interlocking sequences such as timed delays, door priority hierarchies, or access group assignments. The housing and circuitry are designed for industrial environments, with components selected for reliability under continuous operation. Typical installation environments include facilities requiring contamination control, where airlock integrity is critical to operational compliance.

This system is purchased by facility managers in pharmaceutical, biotech, and semiconductor manufacturing sectors, as well as by integrators of access control systems. Buyers typically source it for new builds or retrofits where compliance with ISO 14644 or similar cleanroom standards is required. Packaging is standard industrial carton with internal foam padding. Lead time and incoterms must be confirmed directly with the supplier, as they vary by order volume and delivery location. MOQ is not stated in the listing and should be verified before placing an order.
