I/O Cards
I/O cards take a number of forms, all of which are GSPI peripherals:
• 24in 16out panel mounted module - 667/1/46085/001
• 24in 4out panel mounted module - 667/1/46085/002
• Intelligent Detector Backplane - 667/1/32910/950
• ST950 CPU I/O kit 24in 4out - 667/1/46014/000
• WiMag Standard Interface kit - 667/1/47210/100
The panel mounted modules 667/1/46085/xxx are mounted on the rear panel of the
controller cabinet and allow direct termination of street cabling without resorting to
the use of additional terminal blocks and soft wire conversion kits.
The ST950ELV CPU I/O card cannot be used in a standard ST950ELV cabinet, it
can only be used in 3rd party cabinets.
The Intelligent Detector Backplanes are mounted in the rack. These provide support
for the connection of up to 4 standard Loop Detector Cards such as Siemens SLD4.
The Backplane connects via a ribbon cable to the Loop Termination Board mounted
on the cabinet rear panel. The Loop Termination Board provides the termination
point for 16 Loop Feeder pairs without the use of additional terminal blocks and
twisted wire kits.
All Loop Detector Cards are powered from a dedicated output of the HPU.
The main components of the ST950 ELV system are shown in Figure 1.
