DCS System Specifications (pdf)

DCS 400 19" Rack Frame

The DCS 400 is a 19" base unit with a height of 3.46". It can host a control module as well as several relay modules, logic input modules and analog I/O modules that are connected via internal backplane.

• 10 slots for the insertion of DCS modules.
• 4 position Phoenix type connector for power supply.
• 2 LEDs on the front indicating power.
• Internal backplane with system bus.
• Internal self-resetting fuses.

DCS 401R Control Module

The module represents the interface for relay boards, logic boards, analog level I/O-boards, a monitor module and rotary encoders. It is inserted into slot 1 on the rear of the DCS 400 rack frame. It is controlled from the DPM 4000 via RS-485 remote interface. Maximally 12 relay modules, 5 logic input modules, 2 analog I/O modules, 2 rotary encoders and 1 monitor module can be connected to a single DCS 401R control module.

• Two RJ-45 sockets for connecting the DPM 4000 and cascading several DCS 401R or DCS 401 modules.
• Galvanic isolated RS-485 port.
• Connector for 2 rotary encoders.
• Connector for DCS 420 monitor module.
• Monitoring via watchdog circuitry.
• Service-functions and testing-software for all connected modules.
• 6 binary switches for setting addresses and selecting service-functions.
• 1 pen-tip pushbutton – test start.
• 3 LEDs - red, yellow, green for test mode and status.
• A maximum amount of 8 modules DCS 401R or DCS 401 can be cascaded.

DCS 405R Extension Module

The module is used to provide connection to another DCS 400 rack frame and/or other DCS 400 boards. This is useful in situations where there are more cards on a given DCS 401R than a single DCS 400 frame can support.

Installation Notes
In the first DCS 400 rack frame the DCS 405R extension module always needs to be installed in the first empty slot. In the DCS 400 extension unit - the second unit installed - the DCS 405R extension module always needs to be installed in slot 1.

DCS 408R/409R Control Relay Modules

These modules provide relay contact closures for use in switching audio or other control functions. The 408R is capable of switching 70 V or 100 V speaker lines. The 409R is capable of switching line level audio signals or control outputs. The 408R can also be used to provide contact closures where higher voltages and/or current may be involved.

• 5 line relays, each with 2 switching contacts.
• Phoenix type connector for all contacts.
• 5 relay control-LEDs.
• Configuring the signal distributor is possible through separating wire-bridges.
• 12 DCS relay modules can be cascaded.

DCS 412R Logic Input Module

The module provides inputs for control lines, pushbuttons, switches and sensors, allowing the evaluation of their individual status (ON/OFF) in the DPM 4000 system.

• 12 inputs.
• Selectable polarity of each input.
• Floating inputs can be realized via the separation of wire bridges.
• Separate connections for power supplies of pushbuttons, contacts and sensors.
• Phoenix type connector for all inputs.
• Maximally 5 DCS412R/DCS412 modules can be cascaded.

DCS 416R Analog I/O Module

The module provides analog input and output interfacing capabilities for use in monitoring and control functions. Both inputs and outputs are capable of handling 0 to 10 V DC with 256 distinct levels. Potentiometers for volume control can be interfaced using the provided reference voltage output.

• 8 analog inputs.
• Voltages of 0 to 10V DC or a potentiometer to each input.
• Output for reference voltage 10V DC.
• 8 analog outputs 0 to 10V DC.
• Phoenix type connector for all inputs and outputs.
• Maximally 2 DCS 416R / DCS 416 modules can be cascaded.

DCS 420 Monitor Station

The DCS 420 Monitor Manager is a 2RU unit offering acoustic control and visual level metering of audio in the system. Switching and displaying of up to 250 audio signal sources, as well as, controlling the volume is carried out via front panel control switches.

The DCS 420 receives its audio feed from the monitor output of the DPM4000. DCS 420 system control functions are carried out through a connection to the DCS 401 controller module. The front panel controls of the DCS 420 offer audio level and line control switching of either the input signal or the output signal of the system amplifiers.

With several external sound sources connected, switching is performed through the DCS 409R module. When using remote-amplifiers, switching audio signals to the monitor bus is accomplished directly inside the amplifier. The signals are transmitted via remote interconnection cables.
