Counter/Timer Accessories and Cables
Shielded I/O connector block for easy connection of I/O signals to the counter/timer
devices. The screw terminals are housed in a metal enclosure for protection from
noise corruption. Combined with a shielded cable, the SCB-68 provides rugged, very
low-noise signal termination. The SCB-68 also includes two general-purpose
breadboard areas.
SCB-68 ..............................................................................................................776844-01
Dimensions – 19.5 by 15.2 by 4.5 cm (7.7 by 6.0 by 1.8 in)
