5.4.2 DCS 401 CONTROL MODULE
The module is to be mounted on the rear of a PA-system rack-shelf or inside of a suitable distribution box. It
serves as an interface for the connection of relay boards, logic input boards, analog I/O boards, and rotary
encoders. The module is controlled via the RS-485 remote port of the DPM 4000.
A single DCS 401 control module can host a maximum of 12 relay modules DCS 408 / DCS 409, five logic input
modules DCS 412, two analog input / output modules DCS 416, and two rotary encoders. Relay modules are
connected to the CN7 connector using the supplied flat-wire cable. DCS 408 or DCS 409 boards can be installed
in any order. Logic input modules are connected to the CN8 connector while analog I/O modules have to be
connected to CN9. The CN12 connector allows the connection of two rotary encoders.
Features
• Two RJ-45 connectors for connecting the DPM 4000 and for cascading several DCS 401 control modules
• Galvanic separation of the RS-485 interface port
• One connector each for relay modules, logic input modules and analog signal modules
• One connector for two rotary encoders
• Internal monitoring via watchdog circuitry
• Line surveillance via polling
• Two binding posts for the connection of an external supply voltage source
• Service functions and testing software for all connected modules
• Binary switch for address setting (0 - 7)
CAUTION: Each participant connected to the DPM 4000 remote port has to have an exclusive address.
Each address can be used only once.
Installation Note
Mounting the module and establishing the connections are solely admissible when performed in accordance to
VDE 0100 and EN 60065 regulations.
DCS 401 module printed board assemblies need to be grounded at their fixing points (e.g. using a metal bolt).
