The B4 is an addressable digital Brain Board that can control up to 32 input or output points in distributed I/O applications. It is designed for use with the G4PB32H mounting rack for single-point digital I/O or the PB32HQ mounting rack for quad pak digital I/O (four points of I/O per module). It features a 70-pin header connector to attach to a digital I/O mounting rack. Up to 16 B4 brain board may be linked on a single Pamux bus to control up to 512 points of digital I/O. Each B4 requires 5VDC ±0.1V at 0.5A (plus an additional 0.5A if a terminator board is installed). It includes eight jumpers. Jumpers 1 through 4 set the address, jumpers 5 and 6 set the watchdog functionality and jumpers 7 and 8 determine the behaviour of the reset line.
