What 10k Thermistor sensors are compatible with the I/A Series MNL and MNB families of controllers?

Issue

What 10k Thermistor sensors are compatible with the I/A Series MNL and MNB families of controllers?

Environment

I/A Series LON Controllers (MNL-xxxxx)

I/A Series BACnet Controllers (MNB-xxxxx)

Cause

Specification information

Job spec requires a specific family of sensors.  Need to know how to compare the TC curves.

Resolution

Compatible sensors that have a built-in 11k shunt resistor include the TS-5711-850, TS-57011-850, TS-57031-850, and TSMN-90110-850 Series.

Any sensor that matches resistance to temperature curve for a 10K Thermistor Type G (U.S.Sensor), Type 9 (Dale/Vishay) or Type III (ACI Series AH) can be used with the I/A Series MNL and I/A Series MNB series controllers, provided that a 11k ± 0.1% 1/8 watt resistor is wired in parallel with the sensor.
The input has a range of -10 to 135 °F (-23.3 to 57.2 °C) with an accuracy of ±1% of span.
