SLSC Modules



Leverages NI’s SLSC Platform

Easily access and interact with your electronic control unit (ECU) or device under test (DUT). OPAL-RT has created powerful, open, and flexible test systems from off-the-shelf components that leverage NI’s Switch, Load, and Signal Conditioning (SLSC) platform.

Off-the-Shelf, Powerful, Fast and Configurable Platform

Our new range of SLSC modules enables HIL users to maximize their time and resources through our configurable signal conditioning stage, ensuring that signals are the right level and type, as well as by providing configuration for voltage level shifting, dividing and multiplying or integrated filters and impedance matching.

Every card provides an on-board flexible fault insertion unit (FIU) giving full relay control during testing when applying faults to the Device Under Test through NI’s VeriStand interface.

SLSC Modules Highlights


OPAL-RT’s suite of SLSC cards combine the FIU (Fault Insertion Unit) and Signal Conditioning on the same card—this saves users valuable rack space and consolidates multiple functions in one place.

Fault Insertion Units (FIUs)

FIU allow users to better understand how the test units react under all operational circumstances—including unexpected, adverse, or unlikely yet possible events.

Signal Conditioning

A superior, configurable signal conditioning stage of testing/simulation, ensuring that signals are the right level and type, and handling of signals for various parts of system testing.

Flexible Configuration

Flexible configuration of the platform and cards themselves allow users from various sectors with differing priorities to select what is important in their fields or sectors.

Flexible Load Testing

Flexible load testing allows engineers and QA personnel to see the DUT or ECU subjected to extreme, yet controlled, conditions as required to quantify the strength and resilience of the unit.
