DLIM 2 Door Interlock Module

Designed to provide safe and effective door interlocking, this compact 2 Door Interlock Module ensures that only one door can be open at any time — ideal for cleanrooms, airlocks, secure areas, laboratories, and restricted access environments.

When installed, the system intelligently requires one door to be fully closed before the second door can be released, preventing unwanted airflow, contamination, or security breaches.

Key Features:

• Controls two doors for interlocking
• When the first door opens and closes properly, the second door will unlock and open.
• Separate outputs for Door 1 and Door 2 locks
• Separate push-to-exit inputs for Door 1 and Door 2
• Prevents both doors from being unlocked simultaneously
• Compact module design

With independent lock outputs, you maintain full control of each door’s locking mechanism. The separate push-to-exit inputs allow safe and convenient egress while maintaining the interlock logic.

Small in size but big on functionality, this module fits neatly into control panels and enclosures without taking up valuable space.
