SCC-A10

The NI SCC-A10 is a two-channel voltage attenuator analog input module for SCC systems. Each channel divides the input voltage by 10 and provides differential instrumentation-amplifier buffering.

Overview

Product overview

Key product information and technical features.

The SCC-A10 conditions voltage signals within the NI SCC ecosystem. Its low-impedance amplifier outputs support DAQ scanning, while built-in high-impedance bias resistors accommodate floating or ground-referenced sources without external bias resistors.

Installation requires an SCC-68 or SC-2345/2350 carrier, a 68-pin E/M Series DAQ device, and appropriate cabling and power.

  • Independent divide-by-10 attenuation on both channels.
  • Differential instrumentation amplifiers provide buffered, low-impedance outputs.
  • Built-in bias resistors support floating and ground-referenced input signals.
  • Includes DAQ overvoltage protection and supports cascading with other SCC modules.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

Is the SCC-A10 a matrix switch?

No. NI identifies the SCC-A10 as a two-channel voltage attenuator analog input module for SCC.

Can it accept floating signal sources?

Yes. Built-in bias resistors allow floating or ground-referenced inputs without additional external bias resistors.

How is attenuation handled in voltage readings?

If software has not already applied SCC-A10 scaling, multiply the DAQ voltage reading by 10.
