EM-M17b F/UI -CONVERTER FEATURES: • Eight frequency ranges • Isolated input • High linearity • Various input options • Output signal mA or V • Good output filtering • Output short circuit protected • Adjustable zero & gain • Rail mountable EM-M17b converts applied frequency to 0...10 V or to 4...20 mA signal. Frequency range is selectable with DIP-switches. Converter can be used with most of the commonly available transducer types. Frequency can be applied also as a pulsed voltage signal. The frequency input can be isolated optically if transducer supply and SW1/1 is left open. Converted signal is filtered using a 2nd order filter so that the ripple of the incoming frequency is efficiently attenuated. The output of EM-M17b is both short circuit and overload protected. Operating voltage range is wide and the supply is protected against incorrect polarity.tttttttttttttttttttttt TECHNICAL DATA: Input settings Input range Input impedance Frequency ranges Output filtering Output ranges Adjustment ranges Oper. ambient temp. 20...32 Vdc 50 mA max. 0.1 % typical < 100 ppm/°C 15 Vdc 8.5 Vdc (namur) open collector NPN open collector PNP NAMUR pulse (isolated) 4...25 V appr. 2 kohm 0...200, 500, 1000 Hz 0...2, 5, 10, 20, 50 kHz 10 Hz ( -3 dB ) 0...10 V RL > 1 kohm 4...20 mA RL < 500 ohm Gain ± 15 % Zero - 25 % 0...60 °C SETTINGS OF EM-M17b FREQUENCY 1 2 3 4 5 6 7 8 INPUT MODE 1 2 3 200Hz 4 NPN OPEN-C 500Hz PNP OPEN-C 1kHz 86mm Operating voltage Current consumption Linearity error Thermal drift Transducer supply 79mm 2kHz NAMUR ISOL.
