Quantum Local I/O
Overview
A local I/O configuration is contained in one rack and includes all Quantum modules
mounted in a standard Quantum backplane. Quantum Local I/O can be as few as
one I/O module (in a three slot backplane), or as many as 14, along with a CPU and
power supply in a single 16 slot backplane.
If required for the application, system interface modules are also included in the
Local I/O backplane. These modules could consist of one RIO processor or network
option modules.
I/O Configuration
The following figure is an example of a typical local I/O configuration.
NOTE: A maximum of 448 digital I/O points (14, 4x8 digital I/O modules), or a
maximum of 48 analog input channels (six 8-channel analog in modules) and 32
analog output channels (eight 4-channel analog out modules) may be serviced in a
single local I/O rack.
