National Instruments 779475-01 Terminal Block
Part Number 780463-01 is the identifying part number for the National Instruments SCC-68 Terminal Block. This I/O connector block is used for easy signal connection with DAQ devices inside the NI M Series or E Series. The module consists of screw terminals and a breadboard area for I/O signal connection and bus terminals for external power and grounding. The four SCC slots in the module can be used to integrate devices like thermocouples, strain gauges, RTD input, frequency input, current input, voltage attenuator, load cell input, accelerometer, etc.
The typical power requirement of the 779475-01 (at +5 VDC, ±5%) is 1 mA with no signal conditioning installed. The maximum power consumption depends on the SCC modules installed and the circuits constructed on the breadboard area. When an external power supply is used to power the module, the power supply must provide an output voltage of 4.75V (min) to 5.25V (max). Likewise, the current output must be 2A (max) whereas the minimum output current depends on the load present.
The module is also protected against overcurrent (fused at 2 ADC), overvoltage, and reverse voltage (±20 VDC max). For safety purposes, note that the maximum working voltage at Channel-to-earth is 11 VDC. The 779475-01 features a 68-pin male SCSI connector for I/O purposes. Likewise, there are 4 SCC sockets that support analog input, digital I/O, and feedthrough. Similarly, there are 84 screw terminals (54 - analog and digital I/O, 20 - SCC, 8 - bus, and 2 - external power). Furthermore, it also has a thermistor with an accuracy of ±0.3 °C (over a 0 to 55 °C range), and a wire gauge with a diameter of 14-26 AWG, a tightening torque of 0.5 to 0.6 N.m, and a strip length of 7 mm.
The 779475-01 has physical dimensions of 9.63 x 7.00 x 2.09 inches and weighs 1 lb 6 oz. The operating temperature range of this part is 0 to 55 °C whereas the storage temperature is –20 to 70 °C. The relative humidity level supported by the module is 5 to 90% RH (noncondensing).
