1. Description
MCR-1,2,4CLP-I/I-00 passive isolators are used for
the electrical isolation and processing of analog
0(4)… 20 mA standard current signals. The blocks
provide electrical isolation between the control
electronics and process I/O. In addition, interference
signals above 75 Hz are effectively suppressed.
Input and output circuit do not require separate
auxiliary power. The modules obtain this power from
the input signal.
The modules are snapped onto symmetrical DIN
rails in accordance with EN 50 022.
When using passive isolators, ensure that the
current-driving voltage of the measuring transducer U
B
is sufficient for driving the maximum current of 20 mA
over the passive isolator with the power loss of
U
V
= 2.5 V and the load R
B
.
This means:

The graphic shows the input voltage of U

If you know your load, the lowest voltage, which the
sensor should use to drive a maximum current of 20
mA via passive isolators and loads, can be read from
the Y-axis.

3. Connection Notes
To ensure problem-free operation, the signal source
for the passive isolator must
supply a sufficiently high voltage:
