A computing subsystem includes a plurality of drive-sense circuits operable for coupling to a plurality of loads and a processing module operable for coupling to the plurality of drive-sense circuits. A drive-sense circuit generates a small magnitude analog drive signal based on a reference signal, regulates the small magnitude analog drive signal as a characteristic of a load, generates a change signal based on regulation of the small magnitude analog drive signal, and generates a digital signal based on the change signal, wherein the digital signal is indicative of the characteristic of the load. The processing module is operable to receive a set of digital signals from at least some of the plurality of drive-sense circuits and process the set of digital signals to produce a plurality of frames of load data regarding the plurality of loads.
