Product short description:
- 100 ohm Pt RTD or 0-900 ohm input
- 4-20mA output (sink/source)
- 12-32V DC loop/local power
- USB configuration
The TT231 model is a space-saving two-wire transmitter that converts a 100 ohm Platinum RTD 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.

TT231: RTD / Resistance Input Two-Wire Transmitter Description
The TT231 model is a space-saving two-wire transmitter that converts a 100 ohm Platinum RTD 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.
The transmitter provides sensor excitation plus performs linearization, lead-wire compensation, and lead-break detection.
Setup and calibration are fast and easy with a convenient USB connection to your PC and Acromag’s Windows configuration software.
Advanced signal processing capabilities, variable range input, and convenient USB programming make this instrument a very versatile temperature measurement device.
These transmitters can withstand harsh industrial environments and operate reliably across a wide temperature range with very low drift. They feature RFI, EMI, ESD, EFT, and surge protection plus low radiated emissions.
