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 signals. 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 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.
