Connecting Extension Bases to an Extension Module
Verify that the power of the DS400/DS600 has been turned off before connecting the extension
module/extension base.
Mount the extension module onto a stand-alone model of the DA main unit or an expandable
model of the DS sub-unit. Wire the module to the extension base with an extension cable. You
can wire one extension module to one of these units. In addition, you can wire a maximum of
three extension bases at the same time to the extension module. It is not possible, however, to
wire extension bases in such a manner that the total sum of modules already mounted on the main
unit/sub-unit and the extension bases being wired exceeds the maximum number of modules (six
for the DA100 main unit, four for the DS400 sub-unit and six for the DS600 sub-unit) allowed for
mounting on the main unit/sub-unit.
Either a 10-channel universal input module (DU100-11 or DU100-12) or a 10-channel DCV/TC/
DI module (DU200-11 or DU200-12) can be mounted onto each extension base.

Select an unused slot number.
Either a 10-channel universal input module
(DU100-11 or DU100-12) or a 10-channel
DCV/TC/DI module (DU200-11 or DU200-12)
Wiring Distance
The last extension base in the connection can be located at a maximum distance of 30 m from the
sub-unit.
Setting of Terminator On/Off Switch
Set the terminator on/off switch of an extension base to ON for the base that is the last in the
connection. Set these switches of all other extension modules to OFF.
Setting of Slot Numbers
Select an unused slot number for each extension base. This can include, however, a slot number
for an extension module. The following figure shows how the numbers you set correspond to the
positions of slots and relate to channel numbers.
