Nominal Temperature Range: -100?é?? to 924?é?? C, -148?é?? to 1695?é?? F. Over/Under Range Capability ?é??C: -125?é?? to 1250?é?? C, -193?é?? to 2282?é?? F. Average: Resolution: ?é?? 0.25 ?é??C (-100 to 924 ?é??C), ?é?? 0.5 ?é??C (924 to 1250 ?é??C). Accuracy: ?é?? 3 ?é??C (-100 to 924 ?é??C) *Accuracy may be improved by the use of "Set Offset" and "Set Gain" commands in the OPTOMUX command set.. Repeatability: ?é?? 1 ?é??C, Power Requirements: 35 mA at +15 (+/- 0.25) VDC, 35 mA at -15 (+/- 0.25) VDC. The AD8T Type K thermocouple analog input module provides a single channel of optically isolated temperature-to-digital conversion. In addition to optical isolation, this module includes 4000 Vrms transient channel-to-channel isolation, which eliminates any ground loop problems. This module mounts on a G1 analog mounting rack, for example the PB16AH.. Opto 22. Opto 22. AD8T.
