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.
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.
981PB, 982PB, 983PB: Profibus-DP 12-Channel Digital I/O
Active-Low Inputs, Sinking Outputs
12 input channels, 0 to 35V DC range
12 to 36V DC
These modules provide an isolated Profibus-DP network interface for twelve discrete input and/or output channels. The outputs provide direct on/off, high/low, or open/close control of industrial devices.
The ST132 is a low-cost two-wire transmitter that converts a millivolt or thermocouple sensor input to a proportional 4-20mA control signal. Power is received from the output loop current. The transmitter performs signal linearization, cold-junction compensation, and lead-break detection functions.
TC type J, K, T, R, S, E, B, and N or ±100mV input
4 to 20mA DC output
The ST133 is a low-cost two-wire transmitter that isolates and converts a millivolt or thermocouple sensor input to a proportional 4-20mA control signal. Power is received from the output loop current. The transmitter performs signal linearization, cold-junction compensation, and lead-break detection functions.
TT237: Voltage Input, Loop-Power, 2-Wire Transmitter
Multi-range ±1V, ±5V or ±10V input
4-20mA output (sink/source)
12-32 V loop power
The TT237 model is a space-saving two-wire transmitter that isolates and converts a process level DC voltage input to a proportional 4-20mA control signal. A single unit supports multiple voltage input ranges for extra flexibility. Power is received from the output loop current or a local DC supply when using a three-wire connection.
