Product Overview

The 1756-OV32E is an Allen-Bradley ControlLogix electronically fused sinking digital output module. It provides 32 sinking outputs in two groups of 16, each group electronically fused for fault isolation. Installed in a ControlLogix chassis, it is used to drive DC loads such as valves, indicators, and relays in process, packaging, and machine-control systems. The part number 1756-OV32E is supported with detailed technical specifications and is intended for applications requiring grouped output protection and precise electrical control.

Best Suited For

  • ControlLogix chassis-based DC output expansion
  • Grouped short-circuit protected output circuits
  • Applications requiring sinking DC switching of up to 0.5 A per point
  • Installation in industrial systems such as material handling or packaging
  • Replacement or spare module in maintenance inventories
