An inverted and non-inverted output of the sum is provided. Each of the three inputs channels can be A.C. or D.C. coupled or grounded. Each input features the ISRI pseudo differential input for ground loop isolation. This device also features a back panel signal insertion loop for inserting a signal processor between the summer section and the output section.
Inputs are differential voltage sensing, and single ended current sensing.
This fulfills single ended input signal requirement and gives ground loop isolation.
