How can I measure floating analog signals?

Posted on   •  Updated on

We recommend using a SeaI/O-570 module, which has eight 16-bit A/D inputs that are capable of measuring floating, or non-referenced, analog signals.

For instructions and schematics for interfacing a SeaI/O-570 module to floating analog signals, read the Floating Signal Source Wiring Guide section of the Interfacing Analog Signals to SeaI/O-570 Modules resource article.
