Spectrum Controls' 2080 Thermistor Module
2080 thermistor module can provide fully linearized temperature measurements or a wide range of resistance inputs. It's compatible with Allen-Bradley Micro830 and Micro850 controllers, input type, open-circuit detection, and high- and low-range alarms are individually programmable for each channel. It has four channels of thermistor/resistance input, NTC thermistor support, as well as 250 Vdc channel-to-chassis ground isolation. All sensor inputs are converted to temperature without any special programming in your ladder logic.
