The NI SC-2070 is a termination breadboard that connects signal wires to National Instruments DAQ devices, providing a user-friendly interface for integrating analog and digital signals into test and measurement systems. It combines screw terminal connectivity with a general-purpose prototyping area, making it ideal for rapid signal routing, circuit development, and thermocouple applications in laboratory and production environments.
Technical Specifications
Channel Configuration
• Eight differential analog input channels
• Sixteen single-ended analog input channels
• Up to seven thermocouples per SC-2070, with one channel reserved for onboard temperature sensor monitoring
Termination and Connectivity
• 36 labeled screw terminals for secure wire connections
• General-purpose breadboard area with standard tie-points for custom analog, digital, and timing circuits
Signal Conditioning
• Integrated onboard temperature sensor for cold-junction compensation in thermocouple applications
• Silkscreened component locations enabling construction of single-pole highpass and lowpass filters, voltage dividers, and broken thermocouple detectors
– Key Features
The SC-2070 accommodates a wide variety of signal types—analog, digital, and timing—suitable for direct connection to DAQ inputs. Screw terminals accept multiple wire gauges and deliver repeatable connections across test cycles. The breadboard area supports custom signal conditioning without requiring external power.
– Typical Applications
Prototyping and circuit development benefit from the breadboard prototyping area and silkscreened component templates. Thermocouple measurement systems leverage the integrated temperature sensor and designated thermocouple connection areas. Laboratory signal routing, production test configurations, and systems requiring ad-hoc signal conditioning all leverage the flexible terminal and breadboard architecture.
– Compatibility & Integration
The SC-2070 directly interfaces with National Instruments multifunction DAQ boards across legacy platforms: IBM PC/XT/AT, Personal System/2 (Micro Channel), and Macintosh II computer systems.
