Data sheet
The MCR-C-UI-UI(-450)-DCI(-NC) 3-way isolation amplifier
is used to electrically isolate and convert analog signals. The
device provides electrical isolation of analog standard sig-
nals. The module input and output are supplied via integrated
DC/DC converters, which are electrically isolated 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 nega-
tive effects of several sensor circuits connected with one ano-
ther. 3-way isolation enables the universal use of modules
both locally and close to the control system for signal conver-
sion 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 installa-
tion and observe the safety instructions.
Make sure you always use the latest documentation.
