The EM11 I/O board is used for digitizing (analog inputs with A/D or V/F/D converters) and for the output of analog voltage signals, for the input of binary signals (speed), for input/output (binary I/O) and display (LED) of binary information. 

The programmable address decoder calculates the board address, related to the board location.

  • X6: For digitizing analog voltage signals: 
    •  Four channels with A/D conversion, 
    • Four channels with V/F and subsequent F/D conversion (V/F/D conversion)
  • X6: For the output of analog voltage signals: 
    • Two channels with D/A conversion
  • X5: For incremental encoding:
    • One channel for actual speed value and position encoding with inputs for two tracks plus the zero marking pulse;
    • Subsequent digital filter and quadrupling the track frequency of the incremental shaft angle encoder
    • One input for function monitoring
  • X7: For the input and output of binary information: 
    • 16 binary inputs and 8 binary outputs.
    • 4 binary outputs for signal states of connector X5
  • H10/H20: For display:
    • 16 LED's on the front panel, logical order in two bytes:
    • one byte (H10) with red LED's (H11-H18, H11 is the least sign. bit)
    • one byte (H20) with yellow LED's (H21-H28, H21 is the least sign. bit) 
    • independent from binary signals
