      • 1) Only in combination with an appropriate test device, e.g., Flexi Classic or Flexi Soft.
      • 2) Between two requirements on a safety-related response of the device, at least 100 external tests must be carried out.

      Test input response time≤ 1.1 ms
      Switching outputsPush–pull 2)
      Current loading≤ 100 mA
      • 1) The test input may not not be operated when not connected. The test input has a pull-up resistor to activate the sender (sender on) even when not connected. Therefore, an active-switched LOW signal is required to activate the cyclic test with test gap (sender off).
      • 2) Digital output for controlling the downstream test device, not an OSSD according to IEC 61496-1. Short-circuit protected output.
