This module aggregates temperature data from up to 16 independent RTD sensors (such as Pt100 or Pt1000), sequentially routing precision signals through the backplane bus to the central controller. By consolidating multiple temperature points into a single rack-mounted unit, it significantly reduces the wiring complexity and hardware footprint of large-scale thermal monitoring networks.
