The NI CB-68LP is a 68-pin terminal block that breaks out all digital and trigger I/O signals from compatible National Instruments DAQ devices to individual screw terminals. It connects via a vertically mounted 68-pin male SCSI connector and supports wire gauges from 12 to 30 AWG with a torque specification of 0.5 N·m. The unshielded design measures 143.5 mm × 107.4 mm × 30.0 mm and weighs 155 g, featuring standoff feet for benchtop or panel mounting.
