TT231
Transmitter, RTD Input, Loop Power
• 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. The transmitter provides sensor excitation plus performs linearization, lead-wire compensation, and lead-break detection.
