Components to
extend the sys-
tem?
Branches To be able to connect more sensors than there are SENSORNET connections
available at a Universal Transmitter DIQ/S 28X, use the branching module DIQ/
JB (accessory). The DIQ/JB branching module is a simple passive module for
the branching of IQ S

lines.
Relay and current
outputs
The relay and current outputs can be linked with sensors. 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 (system variant or extra component -CR3 or -CR6) is program-
mable as:
 Analog output
 PID controller

Maximum extensibility of the system:
 Passive components: no limitation
 Valve outputs: maximum 1 output per sensor
 Active components: 2
Example:
The variant DIQ/S 284-CR6[-XX] already contains one active
component (DIQ/CR3). The system can still be extended by one
active component.
