12 Channel Temperature Module

The Model 1701 12 Channel temperature module is designed as a data acquisition tool for the Model 1706 10KΩ temperature probes. It enables the collection and transmission of process temperatures from up to 12 probes simultaneously. This module also has 4 internally calibrated resistors that allow for a field self-check feature that can be remotely launched. This ensures instrumentation accuracy and validation while in service.
