Acromag remote I/O modules feature signal conditioners and network I/OÂ 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.
924MB: Thermocouple/milliVolt Modbus-RTU Input Module with Limit Alarms
4 input channels, thermocouple (types J, K, T, R, S, E, B, N) or millivolt (±100mV DC) input
4 alarm channels, open drain MOSFETS (1A DC loads, 0 to 35V DC)
10 to 36V DC, 24V AC power
Modbus-RTU high-speed RS-485
This signal conditioner is a four-channel analog input module with four discrete outputs. It filters and linearizes thermocouple inputs while providing isolation between input, output, power, and network circuits. Cold junction compensation and upscale/downscale sensor break detection are standard.

DT337: Medium DC Voltage Input Four-Wire Dual Transmitter
Dual channels
±1V, ±10V inputs
0-20mA, ±10V outputs
6-32V DC local/bus power
The DT337 model is a four-wire dual transmitter that isolates and converts process-level DC voltage inputs to proportional control signals. Each channel supports DC current or voltage output.
The TT234 model is a space-saving two-wire transmitter that isolates and converts a resistive sensor input to a proportional 4-20mA signal. Power is received from the output loop current or a DC supply when using a three-wire connection.
