THE EXCHANGABLE LOADBOX FOR HIL SYSTEMS

Summary

Many test systems are custom built to match the special needs (protocol, load, function etc.) of each device under test (DUT). The Exchangeable Loadbox separates the test platform from the DUT specific loads and wiring, providing a flexible test system that can be used for numerous DUTs. This setup enables virtual hot swapping of the test system. A new DUT setup can be prepared in advance and when the test system is available, the user can just eject the previous Loadbox from the system, replacing it with the prepared setup.

Furthermore; using test platforms instead of separate dedicated test systems  for each DUT, makes it possible to reduce the number of systems. This lowers overall cost and system maintenance.

The combination of The Exchangeable Loadbox, the Fault Insertion and Signal Conditioning box with commercial I/O provides a modular and flexible test solution optimized for signals used in machines, robots and vehicles.

Application Areas

  • The Exchangeable Loadbox is used in both the Midi and Large test system platforms. The Exchangeable Loadbox together with the Interfacebox can be integrated with test systems from other vendors or pre-existing old systems.

Options

The Exchangeable Loadbox can be equipped with 4mm Brake-Out panels, mounted on the front for selected signals. Computer controlled switching of loads and other signals can also be fitted in the Loadbox if required.

Technical details:

Mechanical:

The Exchangeable Loadbox is built using standard 19” mechanics, 3 or 6 HE. The rear electrical interface is fitted on the top of our FISC box keeping the cable length (and impedance) to a minimum. The Exchangeable Loadbox is easy to remove, simply loosen the front screws and replace with a new configuration.

Electrical:

The electrical interface is defined by customer request using one to four Virgina Panels® Connector (VPC) modules. VPC provides connector modules ranging from high density digital signals (192 3A pins /module) to power supply (50A), RF (18GHz) and Pneumatic (6.9Bar).
