SQIO-MIXEDMODULE1: Analog Inputs

Characteristics | Application | Pinouts

Characteristics

 
  • The analog inputs are arranged in two banks of 8 with a common analog ground connection.
  • The 16 channels are converted sequentially in the order 15 > 14 > 13 >...> 1 > 0. If there is a node or a network that has other SQIO-MODULE1 or SQIO-ADC4DAC4 modules then the sequential conversion process will take place simultaneously on all board modules.
