DoorTek 305-IM - Output Interface Module

The 305-IM is part of DoorTek’s 300-IM Hardware Line. It provides high density, programmable outputs to control doors, lighting, and other equipment. The outputs can be activated or deactivated on the basis of the change in an input status, time or an operator command.

This board is part of a modular system that allows the designer to combine readers (301-IM), inputs (303-IM) and outputs (305-IM) as needed to meet the requirements of the application.
