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.
