What Is SLSC?

NI Switch Load and Signal Conditioning (SLSC) extends the PXI or CompactRIO platform with the ability to add custom front-end modules. With a standardized connectivity and form factor, it eliminates the fault-prone process of point-to-point wiring, simplifying the overall system.

Chris Bakker of HIL Specialty Partner SET discusses his experience in the aerospace industry and how SLSC changed the way modern companies are doing HIL testing.


SLSC reduces time spent on common needs across test systems. Using standard cables, the non-recurring engineering and point-to-point cabling to custom signal conditioning and common sensors is reduced. A key piece of NI's hardware-in-the-loop (HIL) architecture, SLSC amplifies your HIL investment by maximizing reuse.

Key Benefits

  •  Accelerate Time to First Test—SLSC brings a commercial-off-the-shelf approach to the signal conditioning, loads, and switching that are a part of every validation and production system. Utilize a variety of modules to integrate and commission systems sooner while maintaining the customizability you need. Learn more
  • Meet Custom Test Demands—SLSC extends PXI and CompactRIO measurement hardware with high-power relays for signal switching, power loads, and additional inline signal-conditioning capability. SLSC provides more power, cooling, and board space, which makes it ideal for adding I/O types and loads that are not natively supported in those platforms. Learn more
  • Reduce Design and Integration Costs—SLSC has an open architecture that partners and end users can utilize to build custom boards. It eliminates the need to design mechanical and software integration infrastructure that is typically needed with custom hardware. Learn more
