1 Description Features

The MCR-C-UI-UI(-450)-DCI(-NC) 3-way isolation amplifier – Configurable 3-way signal conditioners

is used to electrically isolate and convert analog signals. The – Input and output signal range can be configured via DIP
device provides electrical isolation of analog standard switches
signals. The module input and output are supplied via – ZERO/SPAN adjustment using potentiometers
integrated DC/DC converters, which are electrically isolated
– Can be supplied configured or unconfigured
from the mains (3-way isolation).
The required auxiliary voltage is indicated via a green power
LED. This clearly indicates whether or not auxiliary voltage is
available.
The MCR module ensures the safe decoupling of a sensor
circuit from the evaluation circuit and also prevents the
negative effects of several sensor circuits connected with one
another. 3-way isolation enables the universal use of modules
both locally and close to the control system for signal
conversion and electrical isolation, as well as on the
transmission path for jumpering high load resistors.
Signals are converted by an inductive transmission method.
In addition, a filter connected downstream of the transmitter
reduces possible interference.

WARNING: Correct usage in potentially explosive areas

The module is a category 3 item of electrical equipment. Follow the instructions provided here during
installation and observe the safety instructions.
Make sure you always use the latest documentation.

10 Configuration
CAUTION: Electrostatic discharge
The module contains components that can be
damaged or destroyed by electrostatic
discharge. When handling the module,
observe the necessary safety precautions
against electrostatic discharge (ESD)
according to EN 61340-5-1 and IEC 61340-5-
1.

If the modules are not configured (all DIP switches set to

HYBRID TV1
pos. 0), the module does not have a defined function until the
DIP 1 PHOENIX CONTACT DIP 2 DIP switches have been set.
DIP switches S1 and S2 specify the combination of input and
output standard signal ranges (see configuration table).

Standard Configuration
"NC" versions (...-NC) have the following standard
configuration:
– 0 ... 10 V input
– 0 ... 10 V output
(All DIP switches are set to the "OFF" position)

Opening the Module

Using a screwdriver, release the locked upper housing part
on both sides. The upper housing part and the electronics can
now be pulled out approximately 3 cm.

11 Adjustment
The "ZERO" potentiometer is used to adjust the zero point of
the module and the "SPAN" potentiometer is used to adjust
the final value. Both potentiometers are located on the top of
the module.
NOTE: Module can become damaged
Before commencing the adjustment process,
observe the warm-up phase of two minutes.

Select one of the possible signal ranges using the appropriate
configuration of DIP switch 1 according to the table.
Exception: Bipolar input signals are not permitted for the 4 ...
20 mA and 1 ... 5 V output signal ranges.

14 Specifying the Output Signal Range via DIP Switch 2

Output With Simple Adjustment (0 ... 5 V/0 ...10 V)
Set the output range via DIP switch 2. Please note the
selected input range. Specify the initial and final value of the
input signal using a calibration device. Adjust the output value
with a digital multimeter.
Adjustment after specifying the initial and final value for the 0
... 5 V output: Set 0 V ±0.5 mV at the "ZERO" potentiometer
and 5 V ±0.5 mV at the "SPAN" potentiometer.
Adjustment after specifying the initial and final value for the 0
... 10 V output: Set 0 V ±0.5 mV at the "ZERO" potentiometer
and 10 V ±0.5 mV at the "SPAN" potentiometer.

Set the output range via DIP switch 2. Please note the
selected input range.
Specify the initial and final value of the input signal using a
calibration device.
Record the output value measured with a digital multimeter.
For adjustment with the calibration device, specify the final
value of the input signal range as follows:
"SPAN" potentiometer: Full-scale adjustment point A ±
adjustment tolerance
"ZERO" potentiometer: Output final value ± adjustment
tolerance

Calculation of full-scale adjustment point A: A = Measured

value 1 x Constant/Measured value 2 - Measured value 1
±5 V, ±10 V, 1 ... 5 V, 4 ... 20 mA output signal ranges: If the
initial value is specified at the input, measured value 1 is
output at the output. If the final value is specified at the input,
measured value 2 is output at the output.
0 ... 20 mA output signal range: If the initial value +10% of the
range is specified at the input, measured value 1 is output at
the output. If the final value is specified at the input, measured
value 2 is output at the output.
For the values for the constant, output final
value, and adjustment tolerance, please refer
to the corresponding tables.
