Related model recommendations

1. NI SCB-100: Similar to the SCB-68, but with a 100 – pin connector, offering even more connectivity options. It is suitable for applications that require a larger number of signal connections, such as in complex industrial control systems or high – channel – count research experiments. It can be used in combination with the SCB-68to expand the overall connectivity of a measurement system.
2. NI SCB-68A: An isolated version of the SCB-68. It provides electrical isolation between the data acquisition device and external equipment, which is essential in applications where electrical noise or ground loops could affect the measurement accuracy. When dealing with sensitive electrical signals or in environments with high electrical interference, the SCB-68Ais a better choice compared to the non – isolated SCB-68.
3. NI BNC – 2110: A BNC – based connector block. It uses BNC connectors instead of the SCSI interface of the SCB-68, making it suitable for applications that require coaxial connections, such as in RF signal measurement or video signal acquisition. It can be used alongside the SCB-68in a system that needs to handle both SCSI – connected and BNC – connected devices.
4. NI TB – 2706: A terminal block designed for use with NI CompactDAQ systems. It offers a different form of connection and is optimized for the CompactDAQ platform. While it has a different connection mechanism than the SCB-68, it can be part of a larger NI measurement ecosystem, and users may choose between them depending on their specific system requirements and the type of devices they need to connect.
5. NI SCB – 68 – R: A version of the SCB-68with additional features or modifications. It may have enhanced signal protection, different mounting accessories, or other improvements. It can be considered as an alternative or an upgrade option for users who need specific additional functionality while still maintaining compatibility with the 68 – pin SCSI – based connection standard of the SCB-68.

Installation, commissioning and maintenance instructions

Installation preparation: Before installing the NI SCB-68, ensure that all power sources are turned off to prevent electrical shock. Select an appropriate mounting location based on your setup requirements, whether it’s a rack, bench, or DIN – rail. Gather the necessary mounting hardware, such as screws and brackets. When connecting the SCB-68 to the NI data acquisition device and external equipment, refer to the wiring diagrams provided in the product manual to ensure correct pin – to – pin connections.
