The channels of the digital I / O module sbRIO-9403 can be configured as inputs or outputs during operation. Each channel has transient isolation between the I / O channels and the backplane. Reconfigurable I / O technology (CompactRIO only) enables users to use LabVIEW FPGA to program the sbRIO-9403 and implement custom high-speed counters / timers, digital communication protocols, pulse generation, and other applications.
