Series 650
Temperature Transmitter
4-20 mA Signal, Two Wire Operation, Temperatures from -55 to 180°C
The Series 650 Temperature Transmitter combines low cost with small size making it ideal for a wide variety of HVAC, industrial and commercial multi-point temperature monitoring applications. Non-polarized terminals simplify connection to any 12-35 VDC power supply. Capable of operation with long cable runs, Series 650 Transmitters are well suited for monitoring air or water temperatures at remote locations. Three models in popular ranges factory calibrated within 0.3% of span. All are linear within 0.25% of span and may be recalibrated within low range and span limits shown on Catalog page. Low range is temperature corresponding to 4 mA output. Span is temperature difference between Low and High ranges corresponding to 4-20 mA output signal.
