The National Instruments SC-2070 is a versatile termination breadboard designed for general-purpose applications in industrial and research settings. Constructed as part of the SC-207x Series, the SC-2070 is compatible with a range of NI Multifunction DAQ boards, including those for Macintosh II computers, Personal System/2, and various IBM PC models. It supports up to eight differential or sixteen single-ended analog input channels, providing a robust solution for analog signal conditioning. The board features 36 labeled screw terminals for straightforward field connections, facilitating the integration of both analog and digital signals into DAQ systems.

The SC-2070's breadboard section allows users to create customized timing, digital, and analog circuits, tailored to specific application needs. It incorporates a cold-junction temperature sensor that can be monitored via a dedicated channel, allowing for connection of up to seven thermocouples while ensuring accurate temperature compensation, with an accuracy of ±0.5° C from 0° to 110° C. Users can also disconnect the temperature sensor to maximize the utilization of all available input channels. The SC-2070 is designed with silkscreened component locations for resistors and capacitors, enabling the construction of high-pass and low-pass filters, voltage dividers, and broken thermocouple detectors.

Although the SC-2070 has been designated as obsolete, it remains available for purchase and repair through Apex Waves, ensuring continued support for users. It operates on a +5 VDC power supply (typical 5 mA current draw with no connected circuitry) and comes with a comprehensive user manual and maintenance guide for effortless onboarding and troubleshooting.
