The MCR-C-UI-UI(-450)-DCI(-NC) 3-way signal conditioner is used to electrically isolate and convert analog signals. It ensures the electrical isolation of standard analog signals. The module input and output are electrically isolated and supplied by the mains via integrated DC/DC converters (3-way isolation). A green power LED indicates the required auxiliary energy. It is therefore clearly visible whether auxiliary energy is available. The MCR module ensures the safe decoupling of a sensor circuit from the evaluation circuit and therefore also prevents any mutual interference between multiple sensor circuits. The 3-way isolation means that the modules can be used universally, both on site or in the vicinity of the controller for signal conversion and electrical isolation, and along the transmission path to bridge high load resistance values. Signals are converted by means of an inductive transmission method. In addition, a filter connected downstream of the transmitter reduces possible interference.
