The 845-BB buffer board is an encoder interface designed to allow a single differential line driver type encoder to be wired to eight sets of differential inputs. The inputs may be programmable controllers, numerical controllers, motion controllers, and other positioning systems that require differential encoder input signals. The 845-BB buffer board should be mounted in the I/O cabinet and will provide a degree of immunity to electrical noise. The buffer board is powered with 24V DC, 1 A maximum. Internal voltage regulator circuits make available 12V DC as encoder power. All connections are made via terminal strips mounted on the buffer board.
