Power Input
The sbRIO-9687 interface board must be powered with a +24 V DC supply. The power supply
should have a maximum output current higher than the current consumption of the interface
board and all attached inverters. Refer to the sbRIO-9687 Specifications for maximum current
consumption.
The sbRIO-9687 power input is protected against reverse polarity, and it uses a 10 A fuse to
provide protection for overcurrent. Littlefuse Series 314 is recommended, but any compatible
fuse can be used. Refer to the sbRIO-9687 Specifications for maximum fuse rating.
Caution Disconnect the main +24 V supply before replacing the fuse.

GPIC Signals
The main function of the sbRIO-9687 is to provide an interface between the GPIC controller
and different Semikron inverters. The GPIC controller utilizes the following signals. Refer to
the sbRIO-9683 or sbRIO-9684 documentation for connector pinouts and detailed signal
descriptions.
