5.4.5 DCS 412 LOGIC INPUT MODULE
The module is to be mounted on the rear of PA-system rack-shelves or inside of suitable distribution boxes. It is
for the connection of control lines, pushbuttons, switches and sensors to be able to evaluate their individual status
(ON, OFF) within the PROMATRIX system.
Features
• 12 inputs with 2 binding posts each
• Polarity of each input is freely acceptable
• Each input can be used as floating input by disconnecting wire-bridges
• 2 binding posts provide the voltage source for supplying pushbuttons, contacts and sensors
• 2 connectors for cascading up to 5 modules
• 2 binding posts for the connection of an external supply voltage source
Mounting the module and establishing the connections are solely admissible when performed in accordance to
VDE 0100 and EN 60065 regulations.
DCS 412 logic input module printed board assemblies need to be grounded at their fixing points (e.g. using a
metal bolt).
