Overview

The CR725 provides 8 switched analog excitations for resistance bridge measurements, 2 continuous analog outputs, and 8 digital control outputs. All continuous analog outputs and digital control ports can be active simultaneously; only one switched excitation output can be active at a time.

Each CR725 is placed in an open slot on the CR720 or CR720XL I/O module (the CR720 can accommodate up to 7 cards; the CR720XL can hold up to 14). More than one CR725 card can be used in one I/O module.
