2. General

The DSU 8plus input module is a component of the Dupline bus system
for converting up to 8 voltage signals for transmission over the Dupline
bus.
The inputs of the unit are opto-isolated and make it possible to analyse
DC and AC voltage signals ranging from 0 V to 230 V. The switching
thresholds of 20 V and 190 V can be adjusted individually for each input.
The unit can be configured and operated in a user-friendly manner by
using the keys and the LC display on the front of the unit. For example,
configuring Dupline addresses, switching thresholds and the backlight-
ing are all supported.

3. Installation

The device is installed by snapping it onto the mounting rail.
The patented snap-on system allows easy removal of the device
from the rail by sliding the housing upwards until it is released.

» The USB port is intended solely for updating the sys-
tem firmware. Do not connect anything to it unless
you have been explicitly instructed to do so by us.
» When submenus for system settings or settings
for inputs are called up, the status of addresses on
the bus is no longer updated, generally speaking, if
changes are made to input signals. Synchronisation
takes place when these menus are exited and this can
result in the status of bus values changing. Make sure
that this does not produce any undesirable switching
actions�
