The DULCOMETER Multi-parameter Controller diaLog DACb is a
ProMinent controller platform. In the remainder of this document,
'controller' is consistently used for the DULCOMETER.
the term
The controller has been developed for the continuous measure‐
ment and control of liquid analysis parameters. For water treatment
processes in environmental technology and industry. The controller
is available in a version with 2 or 3 measuring channels. The con‐
troller can operate together with conventional analogue sensors
and actuators.
Typical applications:
Potable water treatment,
n
Waste water treatment,
n
Industrial and process water treatment,
n
Swimming pool water treatment.
n
1 measuring channel with 14 freely selectable measured varia‐
n
bles (via mV or mA input) – depending on the identity code.
PID controller with frequency-based metering pump control for
n
2 metering pumps.
2 analogue outputs for measured value, correction value or
n
control variable (depending on the optional equipment).
4 digital inputs for sample water fault detection, pause and
n
parameter switch-over.
2 relays with limit value function, timer and non-continuous
n
control (depending on the optional equipment).
Power supply for sensors 20 V DC, 70 mA
n
Measured variables and language selection during commis‐
n
sioning.
Compensation for the influence of temperature on the pH and
n
fluoride measured variables.
22 operating languages.
n
Saving and transfer of device parametrisation to an SD card.
n
Subsequent upgrade of the software function by means of an
n
activation key or firmware update.
Interference variable processing (flow) via frequency (digital
n
input), or
Interference variable processing (flow) via mA (VA and AA
n
module) as standard, or
pH compensation for chlorine (VA and AA module).
n
Measured value trend display via the controller display.
n
Third complete measuring and control channel with 14 freely
n
selectable measured variables (via mV or mA input).
Data and event logger with an SD card.
n
Interference variable processing (flow) additionally via mA, if
n
the mA inputs of channel 1 and 2 (VA or AA module) are
assigned or not available (VV module).
External remote setpoint for channel 1.
n
3 additional digital inputs, e.g. for level monitoring.
n
PROFIBUS ® -DP *.
