DescriptionBraun D421 Series Speed (Frequency) Converter to Analog Signal
OverviewThe BRAUN Frequency to Analog Converter Series D421.31 converts speed, flowrate, frequency (or any other physical quantity which can be transmitted as a pulse train) into an analog signal. Programmable in conversion characteristics and signal output: dc-voltage or current, with or without live zero.Characteristics features are extremely wide range, fast tracking response by pulse interval measurement, free programmable conversion parameters, and electronic programming by keys, with display assistance.The time interval between signal pulses is evaluated to measure the process variable. Obviously, this ensures the fastest response to the process signal, tracking from one to the other signal period. A minimum measuring time of 5 milliseconds however is maintained, to ensure stabilization at high signal frequency.The converter signal input is designed to accept a wide range of transmitters: contact free speed sensing probes, incremental encoders, pulse wheel transmitters. Any flowmeter pulse signal output can be converted into an analog flowrate signal. Preamplifiers can be used, and also ex-barriers.Display and analog output may be assigned to any measured quantity. The converter can be customized to suit every application. During its lifetime cycle the converter is completely maintenance-free.
Key FeaturesConversion of speed or a similar variable (flowrate, for instance) as transmitted by a frequency, into an analog signal for any further evaluation Measuring principle combining programmable fast response and averaging within wide limits Frequency range 0 Hz…100 kHz with programmable high and low end 1 Analog Output 0/4…20 mA or 0/2…10 V 5 digit LCD display (8 mm) Universal Inputs, also for magnet inductive sensors (MPUs) Square wave pulse output
Key BenefitsFast, precise and safe Maintenance-free during Lifetime, therefore minimized TCO Establishing a precise relation between analog output and measured quantity by an easily programmable 5 digit scaling factor
