Type 202550
Panel-mounting housing to DIN 43 700
Type 202550 / …
Brief description
The instrument with 96mm x 48mm bezel and plug-in controller module visualizes and controls
variables in analytical measurement (pH value, redox voltage, conductivity, high-purity water,
oxygen, free chlorine, chlorine dioxide, ozone etc.).
The indicator has two analog and two logic inputs. The first analog input is suitable for
connecting a 0(4)—20 mA signal, which can be provided by any type of transmitter (including
2-wire types). The input signal is conditioned, as determined by the configuration, and
displayed. One special feature of the instrument is that the calibration procedures for pH, redox
and conductivity are internally programmed. The second analog input can be used to connect
Pt100 or Pt1000 resistance thermometers.
The instrument features two 4-digit 7-segment displays for indicating the main variable (red) and
the temperature (green). The temperature display is switched off in the default setting. A
separate temperature sensor (Pt100 or Pt1000) can be connected to the second analog input.
This can then be used to display the temperature of the medium and, if required, monitor it by
means of a limit switch. During programming, the displays provide comments on the inputs. A
great variety of control tasks can be handled by the various output options (relay contacts and
/ or analog outputs). The two relay “make” contacts that are provided on the instrument as
standard can be configured as a limit controller and / or pulse width or pulse frequency
controllers, or as a modulating controller. To obtain analog (continuous) controller outputs, the
optional analog outputs must be configured accordingly. All controller outputs can be
configured for a P, PI, PD or PID control action. In the basic version, the instrument provides two
relay “make” contacts and one logic output (0/5V). Two additional outputs can be, according to
choice, fitted with relay changeover contacts and / or analog outputs (process value output or
analog controller output), or with a serial interface (Profibus-DP or MODbus / Jbus protocol)
and /or a supply for 2-wire transmitters.

Calibration options
Parameter level
The controller is adapted to the control loop at
this level. The appropriate parameters appear
here, with symbol and value. Only those
parameters will be indicated which
correspond to the configuration of the
controller (configuration level).
Configuration level
This level is used to adapt the controller to the
control task, or for adaptation of the inputs
and outputs.
07.08 / 00381059
If a transmitter / sensor without integral
calibration function is used as a signal source
(standard current signal), the dTRANS Az 01
can be configured accordingly, as indicator /
controller (for the pH value, for example). It
will then offer one of the following calibration
options, in accordance with the configuration.
Indicator/controller for pH value
The electrode parameters of a pH
combination electrode are subject to
manufacturing tolerances and variations
depending on usage. To compensate for
these changing electrode parameters, the
instrument offers two guided calibration
procedures:
1) 2-point calibration (standard)
This method of calibration makes a fresh
determination of the electrode zero and
slope using two solutions with known pH
values (e.g. buffer solutions).
It should be given preference!
2) 1-point calibration
In 1-point calibration, only the electrode
zero is freshly determined using a solution
with a know pH value (buffer solution).
Problems arising from an incorrect
electrode slope will not be detected by the
user!
This method should only be adopted in
cases where the electrode is not subject to
significant chemical and mechanical
influences.
In addition to the calibration procedures
described above, the instrument offers the
facility of manually entering and adjusting the
zero point and slope (as determined by a
laboratory, for example).
Indicator/controller for redox voltage
The electrode zero of a redox combination
electrode is subject to manufacturing
tolerances and variations depending on
usage.
The instrument provides the facility for a
guided calibration procedure – the 1-point
calibration – for the fresh determination of the
electrode zero, using a buffer solution or a
solution with a known redox voltage.
In addition, the instrument offers the facility of
manually entering or adjusting the electrode
zero (as determined by a laboratory, for
example).
Indicator/controller for electrolytic
conductivity
Calibration of the cell constant
Subject to manufacturing tolerances, the cell
constant of a conductivity cell may deviate
slightly from its nominal (printed) value. In
addition, the cell constant may change during
operation (due to deposits or wear, for
example). This results in a change of the
output signal from the cell. The instrument
offers the user the possibility of compensating
any deviation from the nominal value of the
cell constant through manual entry (range 80
— 120%) or automatic calibration of the
relative cell constant Krel.
Calibration of the temperature coefficient α
The conductivity of almost all solutions
JUMO GmbH & Co. KG • 36035 Fulda, Germany
depends on the temperature. To ensure
correct measurement, it is therefore
necessary to know both the temperature and
the temperature coefficient α [% per °C] of the
measuring solution. The temperature can
either be measured automatically, with a
Pt100 or Pt1000 temperature probe, or set
manually by the user. The temperature
coefficient can be determined automatically
by the instrument or entered manually, in the
range from 0 to 5.5 %/°C
Indicator/controller for free chlorine,
chlorine dioxide and ozone
(as per Data Sheet 20.2630)
The sensor slope is subject to manufacturing
tolerances and changes that develop during
operation.
The instrument offers the facility for a guided
calibration procedure - the 1-point calibration
- to freshly determine the sensor slope
through comparative measurement.
Additional functions of the
JUMO dTRANS Az 01
❏ Programmable response of the process
value output to underrange/overrange
On underrange or overrange, the process
value output can move to the following
operational states:
-4%, 0%, 100% or 110% freely selectable
Example: The instrument is programmed to
4 — 20 mA corresponding to
100 — 500 mV.
It can be set up so that, on falling below 100,
the output signal 4 mA (0%) is either
maintained or will jump to 3.84 mA (-4%). The
3.84 mA value can then be recognized as
“irregular” by a connected PLC.
❏ Bilinear output
This function divides the signal for the analog
process value output into two linear portions
(0 — 50% and 50 — 100% of the output
signal), with a knee-point at 50% of the output
signal. The knee-point of the characteristic
can be shifted along the dotted 50% line. The
factory setting of 50% produces a straightline characteristic.
.
The bilinear characteristic is used when the
“normal” measurement range is likely to be
frequently exceeded.
07.08 / 00381059
Data Sheet 20.2550
Example: The normal measurement range
spans 0—20µS/cm.
However, measurements of up to 80µS/cm
can also occur.
In this case, the range 0 — 100 µS/cm will be
selected, and the knee-point set at 20% of
this range (20% of 100 µS/cm corresponds to
20 µS/cm).
This results in measurements in the range
0 — 20 µS/cm being converted into an output
signal 0 — 10 mA.
Measurements in the range 20 — 100µS/cm
will be converted into an output signal 10 —
20 mA.
❏ The response of the controller relays to
“Hold” can be defined
“Hold” is initiated either manually, using the
keys, by a logic input, or by an alarm event.
The outputs of the relays K1 and K2 can move
to the following (programmable) states on
“Hold”:
0%
Relay de-energized
50% output
100% output
Output
accepted
For dynamic controllers,
50% of the maximum
pulse width or frequency
is produced
Relay is energized, or
maximum pulse width /
frequency
The present output
continues to be
produced
❏ In “Manual” mode, the relays K1 and K2
are operated manually, by using the
keys. Either key or switch operation can
be selected, by a setting at the parameter
level.
Key operation: The relay is switched as long
as the key is pressed (e.g. for manual dosing).
Switch operation: The first key stroke
switches the relay on, the second switches it
off again (toggle action), e.g. for emptying
large tanks.
❏ Simulation of the analog process value
output
The process value output (0/2 — 10 V or 0/
4 — 20 mA, depending on the setting) can be
switched in 10% steps from 0 — 100%, in the
manual mode.
Application: “Dry-run” commissioning of the
plant (without electrodes, fault search,
servicing).
❏ Controller output functions
Output 1 (relay): Switching, with pulse
frequency or pulse width action / limit
monitoring / switched off. Switching
function can be reversed.
MAX / MIN limit comparator.
Output 2 (relay): Switching, with pulse
frequency or pulse width action / limit
monitoring / MAX limit comparator for
temperature input / MIN limit comparator
for temperature input / switched off.
Switching function can be reversed.
MAX / MIN limit comparator.

MIN limit comparator / output of process
value (only for analog process value output)
/ output of temperature process value (only
for analog process value output) / analog
controller output (only for analog process
value output) / no function.
Output 4, logic output: “Hold“ / alarm pulse
contact / alarm steady contact / MAX limit
comparator / MIN limit comparator / no
function.
Output 5, relay or analog process value
output: “Hold” / alarm pulse contact; alarm
steady contact / MAX limit comparator /
MIN limit comparator / output of process
value (only for analog process value output)
/ output of temperature process value (only
for analog process value output) / analog
controller output (only for analog process
value output) / no function.
Limit comparator
(limit monitor)
A limit-monitoring function can be assigned to
the controller outputs 1 to 5 (depending on
the instrument version).
For each one, the direction of switching
(pulled in on going above /below a limit), pullin and /or drop-out delay, and a hysteresis
can all be defined.
Interface
The microprocessor indicator /controller can
be optionally fitted with an RS422 /RS485
interface. This is used for communication with
higher-level systems and integration into a
data network. The transmission protocol can
be either Profibus-DP or MODbus /Jbus.

The lead resistance can be compensated in
software by a correction of the process value.
This is not required if the resistance
thermometer is connected in a 3-wire circuit.
When a resistance thermometer is connected
in a 2-wire circuit, lead compensation can be
provided by using an external compensation
resistor.
