    TT239: Frequency / Pulse / PWM Input, 12-32V DC Loop Power, 2-Wire Transmitter

    • Multi-range 0Hz to 100KHz frequency input
    • Multi-range 0Hz to 3KHz PWM input
    • 4-20mA output (sink/source)
    • 12-32V DC power
    The TT239 model is a space-saving two-wire transmitter that isolates and converts a frequency, pulse, or pulse-width modulation (PWM) input to a proportional 4-20mA signal. You can select to measure either the input frequency or the duty cycle. Power is received from the output loop current or a DC supply when using a three-wire connection.
