National Instruments SCB-12

The National Instruments SCB-12 Terminal Block (Part Number: 787419-01) provides a robust solution for converting Molex Nano-Pitch connectors to QSFP28 connectors, enabling the reliable interfacing of I/O signals for data capture applications. This device is specifically designed to support high-capacity data transfers with capabilities of up to 24 Gbps per lane, making it compatible with protocols such as PCI Express, SAS, and SATA. The SCB-12 effectively breaks out the NanoPitch connector to both a QSFP28 and an 8-pin connector for general-purpose digital I/O signals. It utilizes standard connections for seamless access to DIO signals from a Molex Nano-Pitch I/O cable, while caution is advised regarding voltage levels to prevent damage to the SCB-12 and connected devices.

Equipped with a power LED on its front panel, the SCB-12 allows users to easily monitor the external power connection. The module is mountable on a standard 35 mm DIN rail using the included NI-9913 mounting kit, which ensures secure installation through a clip mechanism. It features versatile mounting options with four bottom holes. The device has a maximum power consumption of 9 W, operates with a line rate of 10.3125 Gb/s, and adheres to Class 1 optical cable power standards with a maximum requirement of 1.5 W. For external power applications, a power supply kit (NI part number 723537-01) is available, supporting an input voltage range of 5.9 V DC. The SCB-12 is designed for a wide array of environmental conditions, supporting an operating humidity range of 10% to 90% non-condensing and an ambient temperature range from 0 °C to 55 °C. It can withstand storage temperatures from -40 °C to 71 °C and relative humidity levels of 5% to 95%, non-condensing, and is capable of functioning at altitudes up to 2,000 meters (800 mbar) at 25 °C. The SCB-12 is engineered for operation in environments classified with pollution degree 2, making it a versatile choice for various industrial automation and control applications.
