DC, AC, and distorted currents can be equally well
measured.
Description
The MCR-S-...-DCI current transducers offer users the
option of ordering a preconfigured device, configuring the
device themselves via DIP switches or programming it with
MCR/PI-CONF-WIN configuration software
(Order No. 2814799).

The MCR-S-1-5-UI-DCI module provides not only the
standard 1 A and 5 A input signals, but also the option of
setting current ranges of 0 ... 0.2 A to 0 ... 11 A
progressively.
In addition to an analog output, these current transducers
also have an optional relay and transistor output, e.g., for
alarm monitoring.
When ordering, the desired configuration to which the
device is to be adapted must be specified (see order key on
page 6 and page 9).

Progressive adjustment of measuring range
True r.m.s. value measurement
3-way electrical isolation according to EN 61010
With optional relay and transistor output
22.5 mm ME housing
With a measuring range of 0 ... 9.5 A to 0 ... 55 A, the
MCR-S-10-50-UI-DCI is ideal for measuring higher motor
currents.
Observe the safety notes on page 11.

Safety notes
During operation, certain parts of this electric
measuring transducer may carry hazardous
voltages. Disregarding this warning may
result in serious personal injury or damage to
property.
MCR-S-...-DCI Modules must only be installed
and started by qualified personnel.
Qualified personnel are people who, because
of their education, experience and
instruction and their knowledge of relevant
standards, regulations, accident prevention
and service conditions, have been
authorized by those responsible for the
safety of the plant, to carry out any required
operations and who are able to recognize
and avoid any possible dangers.
The transducer must not be started up when
the housing is open.
The potentiometers on the front should only
be adjusted using a screwdriver, which is
safely isolated from the voltage at the input.
For applications with high operating
voltages, ensure sufficient distance or
insulation and provide shock protection.
Safe and error-free operation of this device
can only be ensured if transport, storage, and
assembly are carried out correctly and
operation and maintenance are carried out
with care.
6.2
Method of operation
Connection to the input terminal blocks (MCR-S-1-5-...-DCI)
or passing the live conductor through the current transducer
(MCR-S-10-50-...-DCI) induces a magnetic flux in the stripwound core. The magnetic flux density is measured using a
Hall sensor and converted proportionally from the input
current to a voltage (Hall voltage). A subsequent true r.m.s.
value converter enables DC, AC, and distorted currents to
be measured. The signal is amplified for further processing
and made available as a proportional analog signal at the
output.
6.3
Electrical connection
When operating this electric measuring
transducer, the national regulations
(e.g., in Germany, VDE 0100 "Conditions for the
Erection of Electrical Power Installations with
Nominal Voltages Below 1000 V") must be
observed during the installation and selection of
the electrical conductors.

Configuration or programming
Before starting up the measuring transducer, please ensure
that the module configuration data matches the measuring
requirements. The configuration data for a preconfigured
device can be found on the right hand side of the housing.
The MCR-S-...-DCI generation offers the advantage of a
choice between configuration and programming.
MCR/PI-CONF-WIN software can be used to freely program
the true r.m.s. value current transducer.
If you are using an unconfigured transducer, there is a
standard configuration which can be found in the order keys
on page 6 and page 9. If the desired configuration does not
match the label on the side of the housing or the standard
configuration, refer to the section below.
Programming is explained in the software manual. The
user-friendly configuration software runs under all popular
Windows operating systems.

True r.m.s. value: The true r.m.s. value of an AC current
corresponds by definition to the steady-state value that
results from the instantaneous values of this current. This
steady-state value generates the same thermal work in an
ohmic resistor as a DC current of identical magnitude. The
term "true r.m.s. value" simply indicates that distorted and
pulsating currents are also measured.
Arithmetic average value: The arithmetic average value is
used to measure DC currents or to filter a DC portion from a
pulsating current. Using the arithmetic average value on a
symmetrical AC current would result in the measured value
being "0".
The arithmetic average value can be used to make bipolar
DC currents available as analog standard signals at the
output.

Setting the switching threshold
The diagrams below (Figure 5 to Figure 8 on page 15)
illustrate the four possible switching behavior options for the
relay and transistor output. The various options for the
operating behavior in threshold value mode are divided
according to:
– Operating current or closed circuit current principle
– Threshold value triggered when value is below
threshold
– Value is above threshold value
If necessary, the corresponding switching behavior can be
set via DIP switch 7 and DIP switch 8.

Adjustment structure
•
–
After connecting the operating voltage and signal lines,
first adjust the zero point (offset). There should be no
signal at the input (IE = 0).
The analog output must correspond to a preselected
output signal from the table on page 14. Adjust any
inaccuracies using the ZERO potentiometer.
To adjust the measuring range final value, a current
should be specified which is the same level as the final
value if possible. If this is not possible, one of the
following adjustment formulae should be used:
IE
(I - I ))
IA = I0 + (–––
IME x MA 0
•
IE
UA = U0 + (–––
* (UMA - U0))
IME
Example:
The current transducer is to be set to the following values:
Input measuring range: 0 A ... 5 A
IME = 5 A
Output measuring range: 0 mA ... 20 mA
I0 = 0 mA
–
–
–
•
Specify a current for the module, which corresponds to
the threshold value:
Set the TIME potentiometer to "0 s" and turn the
threshold value potentiometer according to the
following instructions (see Figure 5 to Figure 8 on
page 15):
For Figure 5: Turn the threshold value potentiometer
until the yellow "SW" LED lights up.
For Figure 6: Turn the threshold value potentiometer
until the yellow "SW" LED goes out.
For Figure 7: Turn the threshold value potentiometer
until the yellow "SW" LED goes out.
For Figure 8: Turn the threshold value potentiometer
until the yellow "SW" LED lights up.
To prevent switching behavior at the binary output level
during a brief overcurrent, a suppression time must be
set using the TIME potentiometer. If the increased
current is present for longer than the specified
suppression time, the preselected switching behavior
becomes active. The available setting range is 0 to
20 seconds.
When the yellow "SW" LED lights up (relay and transistor
status display), the N/O contact of the PDT contact is closed
and the N/C contact of the PDT contact is opened. The
transistor output switches through.
IMA = 20 mA
Constant current for configuration
IE = 3 A
•
Adjust the calculated output current using the SPAN
potentiometer to IA = 12 mA. When the voltage output is
used, the same adjustment procedure is necessary.

Motor current measurement
The use of MCR-S-...-DCI modules in one or more supply phases of the motor enables what is known as "motor monitoring"
(Figure 13). The MCR current transducer can transfer corresponding standard signals about the motor load to the control
system or service personnel. The true r.m.s. value measurement process means that AC, DC, and distorted currents can be
measured. Even higher frequency currents up to 1 kHz can be acquired.

Acquisition of motor current peak loads
Large industrial motors must be overhauled and serviced at regular intervals. Installing an MCR current transducer in one
phase of the motor feed line enables pulses to be generated with the relay or transistor switching output that can be
measured using a simple meter (Figure 14). The service personnel can then use the motor starts and peak loads as a basis
to provide efficient maintenance corresponding to the number of overloads.
8.3
Lighting monitoring
MCR current transducers can be used for monitoring lighting. If the strength of the current in a circuit is above or below a
specified value after a suppressed switch-on time, there is a fault in the lighting circuit. If the lighting circuit fails, this signal
status can be passed on to another control unit and the emergency lighting can be switched on. The same method can also
be used with other power loads.
