The National Instruments SCC-A10 is a dual-channel module that
accepts input voltage sources up to ±0 VDC. Each channel of the
NI SCC-A10 includes a 10:1 attenuation circuit and differential
instrumentation amplifier with low-impedance outputs for maximum
scanning rates by the multifunction DAQ device. The attenuation circuit
includes high-impedance bias resistors, so you can connect floating or
ground-referenced inputs to the SCC-A10 without adding external bias
resistors. The SCC-A10 also provides overvoltage protection (up to
250 Vrms) for your DAQ system.
When you install an SCC-A10 module in the SC-2345, the carrier
routes the attenuated input signals to two input channels of the DAQ
device, channels x and x+8, where x is 0 through 7.
