SM500 I/O module Function and Technical specifications


Function

  • 8 analog outputs
  • 8 analog inputs
  • 4 integrating analog inputs
  • 16 digital outputs
  • 16 digital inputs
  • 6 LED for status displays
  • 4 incremental encoder inputs
  • 4 absolute value encoder inputs

The signals are not connected to the I/O modules directly. The following interface modules, which are available as accessories, are used for transmitting the signals:

  • SU13 interface module with SC63 for all signals (without signal conversion, no electrical isolation)
  • SB10, SB70, SB71, SU12 interface modules with SC62 cable for digital outputs (with electrical isolation)
  • SB10, SB60, SB61, SU12 interface modules with SC62 cable for digital inputs (with electrical isolation)
