Process Interface
The Process Interface allows simultaneous analysis of the electrical and mechanical
power of up to four motors (generators). The torque and rotational speed are measured
via frequency inputs or as analog signals.

Figure 9-1 shows the Process Interface that is located on the rear panel of the Power
Analyzer (see "Design and Functions" in Chapter 3).
