Industrial standard signals such as \u00b110 V<\/strong>, 0\u202620 mA<\/strong> and 4\u202620 mA<\/strong> are among the most important elements of analogue measurement technology. They are used to transmit physical variables not directly as a technical unit, but as a standardised electrical signal. This allows sensors, measuring transducers, I\/O modules and controllers from different manufacturers to be combined and measured values to be processed reliably. <\/p>\n In practice, these analogue signal ranges are not only relevant for the pure transmission of measured values. The diagnostic capability of the signal, the detection of fault conditions and the conversion into the actual process variable are equally important. Modern modules therefore not only record signals, but also provide functions such as limit monitoring<\/strong>, fault signalling<\/strong> and user-specific scaling<\/strong>. <\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ _builder_version=”4.27.6″ _module_preset=”default” custom_margin=”||||false|false” custom_padding=”||20px||false|false” global_colors_info=”{}”][et_pb_row _builder_version=”4.16″ _module_preset=”default” custom_padding=”0px||0px|||” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_text module_id=”was-sind-standardsignale” _builder_version=”4.27.6″ _module_preset=”default” text_font=”|600|||||||” text_text_color=”#ef7c00″ text_font_size=”24px” header_2_font=”|600|||||||” header_2_text_color=”#ef7c00″ header_2_font_size=”24px” custom_margin=”||14px||false|false” global_colors_info=”{}”]<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_2,1_2″ _builder_version=”4.16″ _module_preset=”default” custom_padding=”0px||0px|||” global_colors_info=”{}”][et_pb_column type=”1_2″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_text disabled_on=”off|off|off” _builder_version=”4.27.6″ _module_preset=”default” text_font=”|300|||||||” text_text_color=”#565655″ text_font_size=”17px” text_line_height=”1.4em” custom_margin=”||20px||false|false” custom_padding=”0px||||false|false” global_colors_info=”{}”]An analogue standard signal assigns a defined voltage or current range to a physical variable.
