or from an external 5 V source. If external 7–42 VDC power is preferred,
you can use the SCC-PWR03 option. Finally, for high-power requirements
(>2 W), you can use the SCC-PWR02 option.
SCC Series Modules
SCCs are available for voltage attenuation, isolation, current input, strain
gauge, and thermocouple input to your E Series device. A feedthrough
SCC allows direct connection to the analog input or analog output signals.
You can customize this feedthrough SCC to meet your specific signal
conditioning needs by adding your circuit design inside the feedthrough
module. SCCs are also available for optically isolating digital I/O signals.
SCC-A10 Voltage Attenuator Module
The SCC-A10 is a dual-channel module that accepts input voltage sources
up to 100 V. Each channel of the SCC-A10 includes a divide-by-10
attenuation circuit and a differential instrumentation amplifier with
low-impedance outputs for maximum scanning rates by the DAQ device.
SCC-AI Series Isolated Analog Input Modules
The SCC-AI series modules isolate, amplify or attenuate, and filter input
signals. Each module has two single-ended analog input channels with a
common input ground. Therefore each channel is not isolated from each
other, but one SCC-AI module is isolated from the next.
