BP-x-PLUS Backplanes
BP-x-PLUS backplanes are available as two-, four- and six- slot versions (BP-2-PLUS, BP-4-
PLUS and BP-6-PLUS correspondingly).
The BP-x-PLUS backplanes serve the same purpose as the BA-x-PLUS backplanes, the
main difference is that these backplanes have an integrated 5 V
DC
/ 5 A power converter on
board and, as a result, do not require a PS-xx power supply for the RTU to work. In order to
operate, the BP-x-PLUS backplanes need only be powered from a single external 12 V
DC
power source. If a backup power source is required then a 12 V lead-acid battery can be
connected in parallel with an input power supply with its output adjusted to 13.8 V level. The
BP-x-PLUS backplanes do not provide any battery charging means by themselves.
