Input Lines (Electrical Specification)
The cameras are equipped with a physical input line, designated as
opto-isolated in
. It is opto-isolated and
can be accessed via the power and I/O interface receptacle on the back of the device. Table 14 shows the
operational limits of the input line, while Figure 22 shows its electrical scheme.
