Snap-AIRTD-1K two-channel, isolated analog input module for 1,000 Ω platinum resistance temperature detectors provides two channels of analog temperature input, with a nominal input temperature range of -328 to 1,562 °F and an input range of 0–4,000 O. The module has an average resolution of 0.042 °C (0.16 O). Used primarily with RTD probes to provide temperature inputs, the module also can be used for making high-resolution resistance measurements.
