Airbag controller
Staff -- Test & Measurement World, 9/1/2004
Kaiser-Threde has unveiled its K3789, a crash-proof device developed specifically for airbag crash-test applications. The K3789 includes electronic time-delay circuits for controlling eight timer outputs, which trigger both DC and AC squibs. The ignition power is about 10 mJ during the first 0.5 ms following firing. The ignitor's permissible resistance range is 1 Ω to 5 Ω. LEDs on each of the outputs indicate if an airbag is correctly fitted and whether the output has been programmed for triggering. Timer channels can be programmed in steps of 0.1 ms within a range of 0.1 ms to 3 s. Programming can be implemented through an RS-422 interface or Ethernet.
