4.9 High Current Interface Board
When the 14Amp power supply is used in the FACP the High Current Interface Board is required to
provide protection for the boards, cards and other 27VDC distribution within the FACP.
The board plugs/connects into the Brigade / PSU Monitor Board (BRD86BPSC) and the 27V DC
output from the PSU is connected to TB1 of the BRD86HCI instead of TB9 on the BRD86BPSC
