EM-M11A MULTISCALE GALVANIC SIGNAL ISOLATOR AND CONDITIONER FEATURES: • Three way isolated • Multiple operating ranges • Two frequency ranges • Dip-switch settable • Isolation up to 1000 V • Adjustable zero and gain • Short circuit protected • Rail mountable EM-M11A is a multiscale conditioner and isolator module for the commonly used signals in automation. The range setting is easily done with DIP-switches and signal frequency limit can be set to 1 kHz or 20 Hz. Every partition (INPUT, OUTPUT, SUPPLY) is galvanically isolated up to 1000 V. Gain and Zero are easy to adjust and there is no mutual effect between these adjustments. The number of possible input/output signal combinations are up to 25 because any of the selectable input ranges can be combined with any of the output ranges. + Adjust ranges Isolation voltage Oper. ambient temp.
