Feeder Terminal REF 541, REF 543, REF 545. 1MRS750443-MBG Analogue output on RTD/analogue module, MEAO1...4 (AO1...AO4) The analogue output function blocks handle the scaling of any internal REAL type IEC 61131-3 based signal to fit a selectable 0...20 mA or 4...20 mA range for use with the outputs on the RTD/analogue module. General REAL type input -10000.00000...10000.00000 The recording can be triggered by any (or several) of the alternatives listed below: · triggering on the rising or falling edge of any (or several) of the digital inputs · triggering on overcurrent, overvoltage or undervoltage · manual triggering via the menu or with the push-button F on the front panel (if configured) · triggering via serial communication · periodic triggering The recording length depends on the number of recordings and inputs used. For example, the following combination of recording length, number of recordings and number of inputs is available at 50 Hz: # recordings \ # inputs 1 5 10 1 1163 cyc. 23.2 s 232 cyc. 4.6 s 115 cyc. 2.3 s 3 412 cyc. 8.2 s 82 cyc. 1.6 s 41 cyc. 0.8 s 10 126 cyc. 2.5 s 25 cyc. 0.5 s 12 cyc. 0.24 s System frequency measurement, MEFR1 (f) Frequency Average Freq.
