DEVICE DESCRIPTIONS
5-82 PROMATRIX System User Handbook 1.1
5.5.8 DCS 412R LOGIC INPUT MODULE
The module is meant for insertion on the rear of the DCS 400 base unit providing connection facilities for control
lines, pushbuttons, switches, and sensors, allowing the evaluation of their individual status (ON / OFF) in the
PROMATRIX system.
• 12 inputs.
• Selectable polarity of each input.
• Floating inputs can be realized via the separation of wire bridges.
• Plug-in binding posts for connecting the power supplies of pushbuttons, contacts and sensors.
• Plug-in screw-flange binding posts for all inputs.
• Maximally 5 DCS412R / DCS412 modules can be cascaded.
Installation Notes
Always equip slots 1-10 of a DCS 400 base unit in ascending order (from the left to the right) leaving no empty
slots in-between.
Combining modules of different type is possible.
Exception: Slot 1 (the slot all the way on the left) always needs to be equipped with a DCS 401R control module
or a DCS 405R extension module.
Mounting the module and establishing the connections are solely admissible when performed in accordance to
VDE 0100 and EN 60065 regulations.
