TTS100 SERIES THERMISTOR SENSORS

Dale 1M1002-C3 Curve 1

Product Support Services continues to get calls asking what the conversion coefficient is for a Thermistor for a particular controller, and can it be used with the new controllers such as MRs. Therefore we have consolidated into this Tech Tip the variety of ways the Thermistor Series Temperature Sensors can be used with Schneider Electric's current family of controllers, including wiring, controller input range and conversion coefficients for both degrees Fahrenheit and Celsius. It makes for a great quick reference. Keep it handy.
