National Instruments SCC-68 Terminal Block
The SCC-68 is a Terminal Block with four SCC slots. The SCC slots can be utilized to integrate lowpass filter, strain gauge, RTD input, frequency input, thermocouple, current input, voltage attenuator, load cell input, accelerometer, SPDT relay, isolated voltage input SCC modules, and more into the SCC system. The SCC-68 is created by National Instruments with the part number 779475-01. This Terminal Block comprises screw terminals and a general breadboard section for I/O signal connection. The NI SCC-68 additionally has bus terminals for external power and grounding. This Terminal Block is RoHS compliant.
The National Instruments SCC-68 is created for easy, expandable desktop measurement systems. The NI SCC-68 provides a simple signal link to M Series or E Series DAQ devices by NI. Other types of 68-pin devices may not operate correctly with the SCC-68. The SCC-68 can be connected to DAQ devices with the use of an RC68-68, SHC68-68-EPM, or SHC68-68 cable. The NI SCC-68 is fabricated with 68 screw terminals for input/output signal interfacing. This Terminal Block has grooves on the bottom of the enclosure so it can be stacked on top of other SCC-68 Connector Blocks. However, the SCC-68 cannot be safely stacked onto another SCC-68 if the back rubber feet are affixed.
The NI SCC-68 has a temperature sensor linked to screw terminals 70 and 71. To utilize the temperature sensor for cold-junction compensation of thermocouple measurements, link CJC+ (terminal 70) to AI channel 7. However, for the most precise thermocouple measurements, NI suggests using an SCC-TC Series module. It has a power requirement of 1 mA at 5 VDC with no signal conditioning installed, and a channel-to-earth maximum working voltage of 11 VDC (CAT I).
The NI device weighs 6 oz, and measures 9.63 x 7.00 x 2.09 in. in physical dimensions. It has a recommended operating temperature range of 0 to 55 °C, and a storage temperature range of –20 to 70 °C, an operating and non-operating random vibration of 0.3 grms and 2.4 grms respectively–all at frequency of 5 to 500 Hz.
SCC-68 Obsolete Status has been announced by National Instruments, but the terminal block will still be available for purchase and repairs by Apex Waves.
