MCR 3-way isolation amplifiers are used to electrically isolate and convert analog signals. The blocks provide 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, see Figure 1). The MCR modules ensure the safe decoupling of a sensor circuit from the evaluation circuit and also prevent 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.
The MCR 3‑Way Isolation Amplifier is used to electrically isolate and convert analog signals. The module provides three‑way isolation via integrated DC/DC converters, allowing safe decoupling of sensor circuits from evaluation circuits and enabling use on DIN rails or close to control systems.
