Summary The STB XBA 1000 I/O base is 13.9 mm (0.58 in) wide. It provides the physical
connections for a size 1 input or output module on the island bus. These
connections let you communicate with the NIM over the island bus and hot swap the
module when the island bus is operational. They also enable the module to receive:
z logic power from the NIM or from a BOS module
z sensor power (for inputs) or actuator power (for outputs) from the PDM
