P520 Signal Processor
APPLICATION
The Honeywell P520 is a rack mounting signal processor that
is compatible with viewing heads in the S5XX and S55XB/BE
series. These include models S506, S509, S511 and S512,
and the advanced viewing head series models S550B/BE,
S552B/BE and S556B/BE. There is only one model of the
P520 available, which is DC powered. A rear backplane PC
Board is required for termination (order part number
REARPCB separately for initial installation).
FEATURES
Rack mounted system, designed to conform to the DIN
41494 19 inch card frame system
3U high and 21HP wide, or 5.06 x 4.18 inches with a
length of 8.66 inches (220mm)
Once rack mounted, together with a power supply and
appropriate viewing head makes up a complete flame
monitoring system
