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.
TT239: Frequency / Pulse / PWM Input, 12-32V DC Loop Power, 2-Wire Transmitter
Multi-range 0Hz to 100KHz frequency input
Multi-range 0Hz to 3KHz PWM input
4-20mA output (sink/source)
12-32V DC power
The TT239 model is a space-saving two-wire transmitter that isolates and converts a frequency, pulse, or pulse-width modulation (PWM) input to a proportional 4-20mA signal. You can select to measure either the input frequency or the duty cycle. Power is received from the output loop current or a DC supply when using a three-wire connection.

TT339: Frequency / Pulse Input, 12-32V DC Local/Bus Power Transmitter
Multi-range 0Hz to 100KHz input
Universal current/voltage output
12-32V DC local/bus power
The TT339 model is a space-saving four-wire transmitter that isolates and converts a frequency or pulse input to a proportional control signal. 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.

VPM2000 Series: Loop-Powered Isolator / Alarm with Display
Loop-powered Process Meter
4-20mA input/output
Solid-state relays
Non-incendive, intrinsically safe
These loop-powered 1/8 DIN digital panel meters provide a convenient and informative display of any 4-20mA signal. A dual line display shows the process value on the top line and the units or a tag on the bottom line. Alternatively, you can display the input in one scale on the top line (e.g. height) and another scale on the bottom (e.g. volume).
