TT339 frequency transmitter converts the rate of pulsed, sinusoidal and other periodic waveform input signals to a proportional 0-20 mA, 0-10 V or ±10 VDC output. It accepts unipolar and bipolar input signals with amplitudes up to 120 Vrms (±170 VDC) and frequencies up to 100 kHz. It comes with free configuration software and a convenient USB connection to the transmitter. It’s usable in hazardous locations (Class 1, Div 2, Zone 2).
