VSI200E Electronic Vertical Speed Indicator with Altitude Encoder

The VSI200E is the most accurate Vertical Speed Indicator available for your aircraft. It exceeds all the requirements of TSO C8e and AS8016A. It also includes a Standard Pressure Altitude Encoder, certified to TSO C88b and AS8003 for direct connection to the transponder. The VSI200E provides the following functionality:

  • Installer selectable for 0-2,000fpm, 0-3,000fpm, 0-4,000fpm or 0-6,000fpm rates of change.
  • Graphic bar indication of rate of change
  • Precision digital rate of change indication
  • Instantaneous display of current Standard pressure Altitude
  • -1,000' to 35,000' Standard Pressure Altitude Encoder

Performance Specification Statement per AS8003 Section 4.4

a) Entire instrument power requirement is 125mA. The encoder section is capable of sinking (grounding) and maximum of 1.15A of current (115mA X 10 outputs).

b) The encoder shall interface to transponder units for which the following Gillham Grey Code Outputs are acceptable (most Mode C transponder units):

  • Each encoder lead is a sink driver that will ground up to a 60V input. Minimum voltage is 3V.
  • Each encoder lead will sink a constant current of 115mA. Minimum current requirement is 525uA.
  • Maximum ON impedance is less than 3 Ohms.
  • Maximum ON (logical high) voltage is 60V. Minimum is 3V.
  • Leakage current for (4) above is less than 100nA
  • Maximum OFF (logical low) voltage is 0.6V. Minimum is 0.12V.
  • Maximum rate of altitude change is 100mS.
  • Switching bandwidth is greater than 1,000 kHz.
  • Provides standard 10-Bit Code.
