MCR-C-...-DC MCR 3-Way Isolation Amplifier INTERFACE Data Sheet © PHOENIX CONTACT - 12/2005 Description Method of Operation MCR 3-way isolation amplifiers are used to electrically The analog signal is first modulated and then electrically isolate and convert analog signals. isolated using a transformer. The blocks provide electrical isolation of analog standard The electrically isolated signal is then provided at the signals. The module input and output are supplied via output, demodulated, filtered, and amplified. integrated DC/DC converters, which are electrically isolated The space-saving 12.5 mm wide ME housing, with plug-in from the mains (3-way isolation, see Figure 1). connection technology, enables the 20 V DC ... 30 V DC The MCR modules ensure the safe decoupling of a sensor supply to be quickly looped through using pre-assembled circuit from the evaluation circuit and also prevent the wire jumpers. negative effects of several sensor circuits connected with MCR 3-way isolation amplifiers can be snapped onto one another. 3-way isolation enables the universal use of symmetrical DIN rails according to EN 60715. 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.
