Overview
Rail-Contact is a DIN-rail mounted device that provides 8 contact closure inputs whose state
can be translated into a DMX512 value. This enables a DMX512 controller to be triggered by
switches such as pressure mats. Rail-Contact provides a useful solution for architectural or
entertainment applications that require interactive lighting systems.
If more than 8 channels are required then two Rail-Contacts can be linked together to form a
16-channel device.
The product is powered via an external DC power supply unit.
