Applicational example:
In a process control system, several different
pH setpoints must be reached in steps and
then maintained. The system is controlled using
a PLC Programmable Logic Controller. The
PLC Programmable Logic Controller indicates
the required standard signals to the controller
via an analogue mA output. The controller auto‐
matically regulates based on the setpoint. The
controller can report the current pH value to the
PLC Programmable Logic Controller via an
analogue mA output.
Electrical connection
The 0/4 ... 20 mA analogue signal
specifies the setpoint and is connected
to terminals XE8 3 (-) and 4 (+) of the
extension unit.
