Overview
Overview of the sbRIO-9687 interface board.
The sbRIO-9687 interface board is an addition to the sbRIO-9683 or sbRIO-9684 General
Purpose Inverter Controller stacked with the sbRIO-9607 CompactRIO Single-Board
Controller. The sbRIO-9687 implements functionality required to control a variety of power
conversion cabinets based on Semikron insulated-gate bipolar transistor (IGBT) modules.
The interface board supports signal inputs from inverter connectors and external connectors,
and it can accommodate many configuration options for a wide spectrum of applications.
Aside from handling all inverter signals, the sbRIO-9687 interface board provides additional
functionality required for more complex systems implementation.
The following figure is a simplified block diagram of the sbRIO-9687 interface board.
