Description
The National Instruments SCB-68 is a Shielded I/O Connector Block designed for optimal performance and compatibility. It carries part numbers 776844-01 and 782914-01, indicating its specific models within the product line. This device is engineered to work seamlessly with a wide range of DAQ devices including the 68-pin X Series, M Series, E Series, B Series, S Series, and R Series.
One of the key features of the SCB-68 is its onboard cold-junction compensation sensor, which is critical for accurate temperature measurements. Alongside this, it offers general-purpose breadboard areas for flexibility in project design, screw terminals for I/O connections for secure wiring, and sockets for electrical component interchange to adapt to various needs. These features make it highly versatile and suitable for applications such as low-noise and rugged signal termination, filtering, voltage attenuation, 4 to 20 mA current input measurement, open thermocouple detection, and signal conditioning.
The temperature sensor of the SCB-68 boasts an output accuracy of ±1.0 °C over a 0 to 110 °C range, with an output of 10 mV/°C, ensuring precise data collection. Its power requirement is modest, typically needing 1 mA at +5 VDC, with a maximum draw of 800 mA from the host computer, making it efficient in its power consumption.
Connection options include 68 screw terminals and a 1 68-pin male SCSI I/O connector, providing flexibility and ease of use in system integration. It supports wire gauges from 14-30 AWG, accommodating a range of wire sizes for different applications. Physical dimensions are 7.7 x 6.0 x 1.8 inches, and it weighs 13 oz, making it compact and easy to handle.
The SCB-68 is built to operate within a temperature range of 0 to 70 °C and can be stored in temperatures
