Our Gen-3 SLSC Modules are designed to have the same functionality and performance of chassis that are integrated in Gen-2 racks.
Digital Isolation SLSC Module Static Load SLSC Module Gen-2 Rack Sample Example: Gen-2 Power Protection Chassis replaced by Power Protection SLSC Module
Gen-3 SLSC Modules can be used standalone or installed in a NI SLSC Chassis which is integrated in a compact rack.
Up to 12 Modules with various functions can be used.
Data Acquisition Equipment (PC or other devices) can be used as SLSC Backend interfaces.
Rear Mounted NI PXIe-1085 Chassis, NI PXIe-8880 Controller,
and two NI-7821R modules shown in example.
Fully Customizable Interface Box for Inputs and Outputs to Unit Under Testing (UUT)
  • Front connectors can be Circular, D-Sub, Micro-D, or custom.
  • The default height of the interface box is 2U (3.5 inches).
  • If more connectors are required, a second interface box or a 4U box can be used.
  • The box can be easily swapped to reuse the EGSE for testing different UUTs.
Example shown for:
4 x 128 contact receptacle pin circular connectors for Input
4 x 128 contact receptacle socket circular connectors for Output
Input Output

The front connectors are designed to easily mate with the UUT’s interface connector parts and match signal traces provided by customer.
This feature allows the use of simple pin to pin cable harnesses for connecting the EGSE to UUT.

Input and Output Connections to UUT

The interface box rear connectors connect to the front of the SLSC modules.
This feature allows the use of COTs cables (mainly with VHDCI connectors) for internal wiring.

Input and Output Connections to SLSC modules
A sample functional block diagram of the EGSE with 4 SLSC digital isolation modules and 2 NI 7821R modules is presented.

LabView Software developed by B&A Engineering is available for loopback testing and module health check.

Various SLSC modules available in stock plus new modules are in development.
