CHANGES FOR
P522AC
SIGNAL PROCESSOR
The P522AC is an upgrade
to the P522 Signal Processor.
It features universal AC input power, a higher current
rating for the relay contacts, a +24V OUT terminal to
power the SEL inputs, and compatibility with all
S5XX vi
ewing heads. All the user features of the
earlier P522 are maintained plus the self-
resetting
fuses, front panel
lettering and the source impedance
resistor requirement of Addendum 1.

VIEWING HEAD CABLE:
When using S5XX
view heads in ordinary locations, use IRIS C-
328 cable
or another cable running in a metal c
onduit to the
control room or signal processor enclosure,
or use
IRIS C-330 cable or a shielded
cable with UL ITC and
CSA CIC (C22.2 No. 239) ratings without conduit.
When using S55X viewing heads in hazardous
locations the above cabling specifications als
o apply,
except that if conduit is used, it must be sealed at both
ends.
