IUC-XX-ADD Isolated Adder/Subtractor

Brand: Pribusin, Inc

The IUC-XX-ADD is a microprocessor controlled Adder/Subtractor. It is easily field configurable to any combination of adding inputs or subtracting inputs. Furthermore, each input can be scaled by a factor of 0-1.25 (or 0-2.5) to allow for unequal process inputs. This flexibility combined with easy field calibration allows for the fine tuning of a process on site with little effort. All that is required to change the calibration settings is a voltmeter and a small screwdriver. 

Example: Adding two Flows of different sized pipes.

Pipe1 = 2 x Pipe2 (by Volume) Scaling Input #1 by 0.67 and Input #2 by 0.33 will result in a combined flow total of 1.0 max. (for scaling factor of 1.25: TP1=3.35V, TP2=1.65V) .
