The NI SCC-68 is an I/O connector block for easy signal connection to an NI X Series, M Series, or E Series data acquisition (DAQ) device. It was designed for simple yet expandable desktop measurement systems. It features 68 screw terminals for I/O signal connection, a general breadboard area, and power bus terminals for external power and grounding. The SCC-68 has four SCC slots for integrating thermocouple, strain gage, RTD, frequency input, current input, voltage attenuator, lowpass filter, load cell input, accelerometer, feedthrough, SPDT relay, isolated digital I/O, and isolated voltage input modules into your measurement system. Find a complete list of modules in the SCC section of National Instruments signal conditioning hardware. The SCC-68 is RoHS-compliant.

CAUTION: NI products typically must be operated with shielded cables and accessories to ensure compliance with Electromagnetic Compatibility (EMC) requirements. To determine if shielded cables or accessories are required for your NI product, refer to the EMC specifications in the product’s user guide or manual. If shielded cables or accessories are required for EMC compliance, do not use unshielded cables or accessories unless they are installed in a shielded enclosure with properly designed and shielded input/output ports and they are connected to the NI product using a shielded cable. If unshielded cables or accessories are not properly installed and shielded, the EMC specifications for the product are no longer guaranteed.
