SQIO-DIN32DOUT32: Inputs

Characteristics | Application | Pinouts

Characteristics

 
  • The digital inputs are arranged in banks of 8.
  • Each input bank has its own common connection and is collectively isolated from other input banks.
  • Inputs can be connected as either current sinking or current sourcing on a per-bank basis.
  • The input update process will take place simultaneously on all board modules.
  • Input Voltage Range: 5 - 24V ±20%
    Inputs will be turned ON by a valid voltage. (i.e. 4-28.8V)
