SCC-68
I/O Connector Block with 4 SCC Signal Conditioning Slots for DAQ Devices
The SCC-68 is an I/O connector block for easy signal connection to a
National Instruments M Series or E Series DAQ device. The SCC-68
features screw terminals and a general breadboard area for I/O signal
connection, and bus terminals for external power and grounding. The
SCC-68 has four SCC slots for use in integrating thermocouple, strain
gauge, RTD input, frequency input, current input, voltage attenuator,
lowpass filter, load cell input, accelerometer, feedthrough, SPDT relay,
isolated digital I/O, and isolated voltage input SCC modules into the
measurement system.
