1 MCR 3-Way Isolation Amplifier INTERFACE Data Sheet Description PHOENIX CONTACT - 12/2005 Method of Operation 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 analog signal is first modulated and then electrically isolated using a transformer. The electrically isolated signal is then provided at the output, demodulated, filtered, and amplified. The space-saving 12.5 mm wide ME housing, with plug-in connection technology, enables the 20 V DC V DC supply to be quickly looped through using pre-assembled wire jumpers. MCR 3-way isolation amplifiers can be snapped onto symmetrical DIN rails according to EN , I Vc, I Vc Figure 1 3-way isolation Make sure you always use the latest documentation.
