ABLOY EL520 Motor Lock with EA420 Controller

Control & power

Control type

Dry-contact input

Power supply

12–24 VDC or 12–18 VAC through EA420

A relay issues a momentary or maintained contact command to the required EA420 controller. Keep the lock powered through its controller; do not drive the lock motor directly.

A suitable smart controller can expose supported functions to Matter. The control type alone does not confirm electrical compatibility or actual position feedback.
