- 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.
