Backplanes

Kingfisher PLUS+ backplanes allow the processor module to communicate with all the other modules in the RTU. The backplane also allows power to be supplied to each module. Backplanes are available in four versions:

• BA-4 4-slot backplane for use with a PC-1 processor only
• BA-6 6-slot backplane for use with a CP-xx processor
• BA-12 12-slot backplane for use with a CP-xx processor
• BA-40 4-slot backplane for use with a CP-xx processor or as a second backplane for a PC-1 RTU

Every RTU requires at least one power supply (PSU-3 with a PC-1 or PS-xx) and at least one CPU module (e.g. PC-1 or CP-xx). Multiple backplanes can be linked together to create an RTU with up to 64 modules. All backplanes can be surface mounted. BA-12 backplanes can also be mounted in a 19-inch rack.
