5.4.3 DCS 408 RELAY MODULE 100 V
The module is to be mounted on the rear of a PA-system rack-shelf or inside of a suitable distribution box. It is
primarily used for switching 100 V loudspeaker lines. The relays can also be used for collective calls, obligatory
reception, as E-relays and D-relays, or for general control purposes.
Features
• Five 100 V line relays, 2 switching contacts each, binding post per contact
• 5 output binding posts, each with 3 screws and label fields
• 5 relay control-LED's
• Configuration of the output distributor is performed through opening wire bridges
• 2 connectors for cascading up to 12 modules
• 2 binding posts for the connection of an external supply voltage source
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.).
Mounting the module and establishing the connections are solely admissible when performed in accordance to
VDE 0100 and EN 60065 regulations.
DCS 408 relay module printed board assemblies need to be grounded at their fixing points (e.g. using a metal
bolt).
The module has to be protected against dropping or splashing water.
