3.6 Using DIQ modules (accessories)
3.6.1 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.

3.6.2 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.
The various application possibilities of the DIQ modules are
shown by means of examples in section 3.11.
