DCS 400 Control System
5.4.1 Characteristics
DCS 400 Series modules increase the PROMATRIX system's control functionality in miscellaneous ways. These
printed board assemblies in the Europe standard format are usually inserted at the rear of a PA-system rack-shelf
or installed in suitable distribution boxes. The DCS 400 system consists of five different modules and additional
extensions:
•
DCS 401
control module for controlling relays, logic inputs, analog inputs and outputs, and rotary
encoders
•
DCS 408
relay module with 5 line relays for 100 V systems
•
DCS 409
relay module with 5 NF or control relays
•
DCS 412
logic input module with 12 floating, bi-polar inputs that are linked via opto-coupplers
•
DCS 416
analog I/O module offering 8 inputs and 8 outputs for 0 V DC to 10 V DC
•
DCS 420
monitor module with 7-segment display, meter instrument and monitor loudspeaker
•
NRS 90240
rotary encoder
A PROMATRIX installation allows integrating a maximum of up to 8 DCS 401 control modules. A single control
module can host up to 12 relay boards of the types DCS 408 / DCS 409 in any sequence. Besides, it is possible
to connect up to 5 logic input modules, 2 analog I/O modules, and 2 rotary encoders.
The PROMATRIX operating system defines the total amount of supported control inputs and outputs. The
PROMATRIX system can manage following amounts of different cards:
•
Control module DCS 401
max. 8 boards
= 16 rotary encoders
•
Relays modules DCS 408 / DCS 409
max. 48 boards = 240 relays
•
Logic input module DCS 412
max. 10 boards = 120 logic inputs
•
Analog I/O module DCS 416
max. 8 boards
= 128 analog inputs / outputs
•
Monitor module
max. 1 per DCS 401
Note:
The power supply of individual boards can be provided either via RJ-45 connection (DCS
401), flat-wire cables (DCS 408, DCS 409, DCS 412, DCS 416) or via 2 binding posts (±24 V)
that are located on each board. The current that runs through the RJ-45 connection or the flat-
wire cables has not to exceed
1 A max.
The current for modules that are connected to the
DCS 401 via flat-wire cables may not exceed
700 mA max.
The connectors CN7, CN8, CN9
share an electronic fuse. For higher currents, it is important that under all circumstances the
binding posts are used instead. When cascading several modules, it is necessary to provide
the power supply anew via binding post connection. Directly cascading up to 7 or 10 modules
is admissible while taking power consumption features of the different types of incorporated
modules into consideration. All modules need to be fed from a single power source! Data
inter-exchange amongst modules has to be established via flat-wire cabling.
CAUTION:
For safety reasons, DCS 400 modules may only be installed in rack-shelf systems or
enclosures that are locked and may only be opened by means of a tool (e.g. screw-driver,
special key, etc.).
When installing modules, make sure to follow all requirements of the EN60065:1993
regulation.
Obeying the regulations for interference-emission (EN55022, class B) and interference-
stability (EN50082-2), DCS 400 module printed board assemblies need to be grounded at
their fixing points (e.g. using a metal bolt).
