Home » Signal Conditioners & Network I/O
Acromag remote I/O modules feature signal conditioners and network I/O  for a broad range of monitoring and control operations where controllers communicate with instrumentation on the plant floor or in the field. Signal Conditioners include signal transmitters, signal isolators, 4-20mA signal splitters, limit alarms and computation modules. These signal conditioners input voltage, current, thermocouple, RTD, frequency, thermistor, load cell, potentiometer, and discrete sensors. These signal conditioners output DC voltage and current, relay, frequency, pulse width modulation and display/readout. Ethernet remote I/O modules communicate via Ethernet/IP, Modbus TCP/IP, Modbus UDP/IP, and Profinet.

    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.
