FIU DS1450 Bus FIU Board

Offers the essential options of electrical failure insertion for the physical layer of buses such as FlexRay. These options include short circuits, open circuit, and varying termination resistance.

DS1450 Bus FIU Board   Spezification
Hardware
  • Supports 4 bus channels in parallel
  • Usable for dSPACE Simulator Mid-Size and Full-Size as well as HIL systems based on expansion boxes
  • Suitable for differential bus sytems (FlexRay, CAN, etc.)
  • Relay-based
Software
  • Uses a specialized ControlDesk® Next Generation failure pattern
Failure insertion options
  • Short circuit to ground and to any user-defined potential (typically UBAT)
  • Open circuit
  • Varying termination resistance
  • Switching cross short-circuits

 

High-Current Failure Simulation

Our high-current failure simulation unit on dSPACE Simulator supports failure simulation on ECU inputs and outputs. One FIU controller card (DS5355) supports up to 19 signal channels on two High Current FIU Relay Trays (DS5390). Due to its modularity, the FIU controller card can be expanded to increase the number of channels. These relay trays allow failures with currents up to 50 A and voltages of up to 300 V. The FIU is controlled from ControlDesk® Next Generation via a serial RS232 or CAN and can be combined with dSPACE Simulator Mid-Size and Full-Size.
