Components to
extend the system
Branches The DIQ/JB branching module (accessory) is a simple passive module for the
branching or extending of SNCIQ lines.
Relay and current
outputs
The relay- and current outputs can be linked with the sensor. Linked outputs can
be used to monitor sensors and for the output of measured values.
A relay output can be programmed as:
 Monitoring relay
 Limit monitor
 Proportional output of measured values (pulse width or frequency output)
 Control unit of a sensor cleaning system driven by compressed air.
A current output can be programmed as:
 Analog output
 PID controller
Modbus Only for the variant DIQ/S 281-MOD
For details, see operating manual "Field bus linking"
Compressed air-
driven cleaning
system
The universal transmitter DIQ/S 281 is prepared for the compressed air-driven,
time-controlled sensor cleaning function. For this, a DIQ/CHV valve module and
if necessary a CH cleaning head is required (both available as accessories). The
cleaning procedure is controlled by the Universal Transmitter. The universal
transmitter provides the supply voltage and control relay for the compressed air
