Models 5B45 and 5B46 are precision isolated 500 Hz to 250 kHz frequency-to-voltage converters that feature excellent high accuracy of ±0.1% max. They accept virtually any TTL level or zero crossing input signal waveform (sine wave, square wave, pulse train or triangular). Both models offer 240 V rms input protection and 1,500 V rms input-to-output isolation in the industry standard 5B Series encapsulated plug-in modular package. * Accepts Frequency Input * Tachometer Applications
