Panel Mount Counter with Analog Input (0-1 mA, 4-20 mA, 0-10 V) to Frequency Output. Low Input Power (12 – 34 VAC or 10 – 48 VDC), No Relay Output, No Analog Output, RS-232 Communication. The PC-AN displays rate or totalized rate for analog process signal inputs. The scaling capability allows the unit to display flow rates corresponding to the output of a flow transducer. Another typical application for the PC-AN is to scale the unit to display power consumption in kilowatts or total utilized energy in kilowatt-hours based on an output of a power transducer. Square root extraction is selectable and can be applied to rate or total, ideal for differential pressure flow meters which have a squared output.
