Introduction
The SCB-68 is a shielded I/O connector block with 68 screw terminals for
easy signal connection to a National Instruments 68- or 100-pin DAQ
device. The SCB-68 features a general breadboard area for custom circuitry
and sockets for interchanging electrical components. These sockets or
component pads allow RC filtering, 4 to 20 mA current sensing, open
thermocouple detection, and voltage attenuation. The open component
pads allow signal conditioning to be easily added to the analog input (AI)
signals and to the DAC0OUT, DAC1OUT, and PFI0/TRIG1 signals of a
68-pin or 100-pin DAQ device.
