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.

    653T: Loop-Powered Single Input, Dual Output Signal Splitter

    • One 4 to 20mA DC input
    • Two 4 to 20mA DC outputs
    • 12-50V DC power from output loop
    • Signal splitter provides two identical outputs from one input signal
    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.

    260A: Limit Alarm; DC Current Input, Loop-Powered

    • 4 to 20mA DC input
    • Single mechanical relay output
    • 4.5V DC from input loop power
    • Hi/lo fail-safe option trips alarms above or below set-point
    The 260A accepts a 4 to 20mA input signal and provides a dry contact relay output if the input exceeds a user-defined set-point limit. Power is received from the input loop.
