Description
The National Instruments SCC-68 Terminal Block, with a part number of 779475-01, is an essential component designed to accommodate four SCC slots for various signal conditioning modules. These modules include but are not limited to a lowpass filter, strain gauge, RTD input, frequency input, thermocouple, current input, voltage attenuator, load cell input, accelerometer, SPDT relay, and isolated voltage input.
This terminal block is RoHS compliant, ensuring adherence to environmental standards. The SCC-68 boasts 68 screw terminals for I/O signal connection, alongside bus terminals for providing external power and grounding, all within a robust construction.
For enhanced compatibility, it supports various cables including the RC68-68, SHC68-68-EPM, or SHC68-68. A unique feature of the SCC-68 is its stacking capability, with dedicated grooves for secure stacking of SCC-68 Connector Blocks, although stacking is not recommended when back rubber feet are attached.
Integrated within the terminal block are temperature sensor terminals at positions 70 (CJC+) and 71, which are crucial for cold-junction compensation in thermocouple measurements. The power requirement for this device is minimal, requiring only 1 mA at 5 VDC when no signal conditioning is installed. Additionally, the SCC-68 is designed to withstand a maximum working voltage of 11 VDC (CAT I) from any channel to earth.
The terminal block is lightweight, tipping the scales at just 6 oz, and has compact physical dimensions of 9.63 x 7.00 x 2.09 inches, making it suitable for a variety of desktop measurement system configurations.
