SQIO-MIXEDMODULE1: Digital Inputs

Characteristics | Application | Pinouts

Characteristics

 
  • The digital inputs are arranged in two groups of 32.
  • Each input group has its own common connection and is collectively isolated from the other input group.
  • Inputs can be connected as either current sinking or current sourcing on a per-group 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)

Application

The digital inputs are arranged in two groups of 32. Each group has its own common connection. The inputs can be configured for either current sinking or current sourcing.
