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.

    TT336: Current/milliVolt Input, DC Power Transmitter

    • Multi-range ±20mA or ±500mV input
    • Universal current/voltage output
    • 12-32V DC power
    DC current and voltage output are both supported on a single model. An optional DIN rail bus can deliver primary or redundant power to multiple units without wiring. Click here to watch a short video highlighting the TT330 Series.

    631T, 632T: Single / Dual Channel Isolator

    • 4 to 20mA DC input
    • 4 to 20mA DC output
    • 12-36V DC SELV, 90-250V AC power
    • Single or dual I/O with a dual output model and full isolation
    These units receive 4-20mA process current inputs and provide isolated 4-20mA output signals. Each channel operates independently and is isolated from the others to prevent interaction between channels. Galvanic isolation eliminates ground loops, reduces noise, and blocks transient signals.

    330i: DC-Powered Isolator

    • 4 to 20mA DC input
    • 4 to 20mA DC output
    • 10-36V DC power
    • Three-way isolation
    Series 330i isolators provide 3-way isolation and do not require re-calibration for different loads. They accept a 4 to 20mA process current input and provide a 3-way isolated process current output signal.
