CHANGES FOR P522DC SIGNAL PROCESSOR
The P522DC is an upgrade of the P522 Signal Processor.
It features a higher current rating for the relay
contacts and is compatible with all S5XX viewing
heads. The front panel and the internal connections
are shown on the right. 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 conduit 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 also apply,
except that if conduit is used, it must be sealed at both ends.
