Two-Door Access Control Interlock Relay Module

✅ Link two door releases. The module sequences the releases so the second follows the first door closing.

✅ Feed status into the logic. The interlock arrangement makes one door's state part of the other's release.

✅ Match fail-safe locks. It works with fail-safe electric locks that provide a status output.

✅ Plan the whole system. Supply, exit behaviour and lock signals are checked as one design before wiring.

Coordinate two doors with an interlock

A relay module that coordinates the release sequence of two compatible doors. It is intended for a two-door access-control design using fail-safe electric locks with status outputs, and the listed contact limit is 5 A at 24 V. Plan supply and exit behaviour as one system, because the module is a relay component rather than a finished door controller.
