- Potentometer / slidewire, thermister input
- 4 to 20mA output (sink / source)
- 12-32V DC loop / local power
- USB configuration
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.
