Hardware-in-the-Loop (HIL) simulation is the standard for developing and testing the most complex control, protection and monitoring systems.

HIL’s rise is the result of two major factors currently affecting product development across all industries: time-to-market and system complexity.

Testing of control systems has traditionally been carried out directly on physical equipment in the field, on the full system or on a power testbed in a lab. While offering testing fidelity, this practice can be very expensive, inefficient and potentially unsafe.

HIL testing offers an excellent alternative to traditional testing methods. When performing HIL simulation, the physical plant is replaced by a precisely equivalent computer model, running in real-time on a simulator appropriately equipped with inputs and outputs (I/Os) capable of interfacing with control systems and other equipment. In this way, the HIL simulator can accurately reproduce the plant and its dynamics, associated to sensors and actuators, provide comprehensive closed-loop testing without the need for testing on real systems.

Lors de la simulation HIL, l’usine physique est remplacée par un modèle informatique exactement équivalent, fonctionnant en temps réel sur un simulateur équipé de manière appropriée d’entrées et de sorties (E/S) capables de s’interfacer avec des systèmes de contrôle et d’autres équipements. La simulation HIL se veut aujourd’hui un standard pour nombreuses industries mondiales.

As one of our main production lines, we deliver special harnesses tailored to our clients requirements including, product development, test and prototype construction and cable harnesses for very specific tasks, such as HV cable harnesses, in very small quantities or small serial production.

Whatever you want to connect, our cable harnesses provide a stable and safe connection between your product and a plant or application. They are strong-contacting, permanent and resistant against various environmental influences.

All parts we manufacture will be checked and tested before they are released from production.

End-of-line (EoL) testers are responsible for testing the overall functionality of the product during the manufacturing process. Under the harsh conditions of the manufacturing environment, test systems must simulate all the relevant conditions, whilst at the same measuring the responses of the equipment being tested. In series production, a high testing throughput rate is crucial. For this reason, the test procedures developed in prototype testing are optimised in order to achieve a short cycle time. A stable electromechanical design is every bit as important here as high-performance hardware and software architecture.

After completion of the development phase for new equipment, the products are subjected to an endurance test. In this test procedure, all load parameters are run down thermally, physically and electrically. It differs from the run-in test, in that weak points in the component are already identified in advance. The boundaries of the devices being tested can be checked using electrical loads. At the same time, these load tests are conducted in climatic chambers in order to introduce additional thermal influences. During these procedures, the test system constantly monitors all the conditions of the equipment being tested. These complete records show the limit values in all test phases and can reveal conclusions about the performance of the equipment being tested.
