Overview

• The module provides 32 discrete outputs arranged in four isolated groups of eight:
  • Group A: A1 - A8
  • Group B: B1 - B8
  • Group C: C1 - C8
  • Group D: D1 - D8
• Each group has its own common.
• Outputs are of negative logic or sinking type, meaning the ON state results in an active low output.

Specifications
