National Instruments SCB-68 HSDIO Connector Block

The SCB-68 HSDIO (Part Number: 782914-01) from National Instruments is a shielded I/O connector block that is designed to facilitate high-performance signal connections across a wide range for test and measurement applications. This connector block is equipped with 32 digital single-ended I/O channels in addition to 6 control I/O channels that are also single-ended. As a result, the device offers enhanced precision for signal transmissions. 

Showcasing flexible synchronization capabilities, the channel-to-channel skew of the SCB-68 HSDIO’s 32 single ended DIO channels is only 32 ps. The propagation delay of these channels is typically 1.1 ns, providing efficient data transfer for all manner of test setups. The connector block also features 6 single-ended control I/O channels, with a typical trace impedance of 50 Ω. In terms of connectivity, the SCB-68 HSDIO boasts 72 screw terminals along with a male 68-pin VHDCI connector, ensuring stable yet flexible connections with wire gauges that range from 14 to 30 AWG. 

Designed for operation within diverse laboratory and industrial environment conditions, the SCB-68 HSDIO has an operating temperature range of 0 to 70 °C within a noncondensing relative humidity range of from 5% to 90%. When nonoperational, the connector block can be safely stored within a storage temperature range spanning from -20 to 70 °C, with the same noncondensing relative humidity range. 

Users can have peace of mind when operating the NI SCB-68 HSDIO, as it is fully compliant with numerous safety standards including IEC 61010-1, UL 61010-1, and CSA 61010-1. These standards safeguard the device from hazardous voltages- enhancing performance and longevity of the hardware. 

The physical dimensions of the connector block measures 14.7 × 14.7 × 3.0 cm (5.8 × 5.8 × 1.2 in.), and it weighs in at a mere 650 g (1 lb 7 oz). The compact form factor of the device make it an excellent choice for test set ups that have limited space.
