3.8 Using DIQ modules (accessories)
Note
The various application possibilities of the DIQ modules are shown by
means of examples in section 3.13.
3.8.1 DIQ/JB
The DIQ/JB module is a passive branching module and can be used for
the following purposes:
 To extend the IQ S
ENSOR N ET SNCIQ(/UG) cable and the SACIQ
sensor connection cable, e.g. to connect a sensor that is located
farther away to the DIQ/S 182 XT-4-PR.
 Connection of another sensor to the DIQ/S 182 XT-4-PR if all
SENSORNET connections are already in use. Example of the
connection of four sensors to the DIQ/S 182 XT-4-PR.
Fig. 3-22 DIQ/JB open.
The DIQ/JB module has seven potential free terminals. To extend or
branch lines, connect the three IQ S
ENSOR N ET wires to each other
one-to-one at any terminal.

3.8.2 DIQ/CHV
The DIQ/CHV module is a valve module for the automatic relay-
controlled compressed air-driven cleaning function in the System
182 XT-4. It provides four additional potential free terminals to branch
(extend) interface lines. For each sensor that is to have compressed air
cleaning a DIQ/CHV is required.
