- Platinum RTD or copper RTD (resistance temperature sensor) input
- DC voltage/current output
These models convert sensor inputs to proportional process current or voltage output signals. Excellent accuracy and stability ensure reliable measurements in harsh industrial environments. 3-way isolation. Input, output, and power circuits are isolated from each other.
250T: Loop-powered transmitter series
350T: DC-powered transmitter series
450T: AC-powered transmitter series
Ambient Temperature Range
