PCI/DSP Connections
Opto-Isolation
The PCI controller contains Opto-Isolation for all the Discrete I/O except the In_Position bit.
There are four Opto-inputs and one Opto-output per axis. There is an additional 24 lines of
optically isolated, bi-directional User I/O. All I/O operates from 5-24 volts.
