1756-OV32E Allen Bradley | 32 Point Electronically Fused D/O

Allen Bradley 1756-OV32E ControlLogix 32-Point Sinking Output Module

Product Overview

The 1756-OV32E (1756-OV32E) is a high-density digital output module within the Allen-Bradley ControlLogix platform, specifically engineered for space-constrained applications requiring a high number of control points. Featuring 32 sinking output channels, this module is designed to switch DC loads by completing the circuit to the negative rail (common).

A standout feature of the 1756-OV32E is its integrated electronic fusing. Unlike standard modules that require external fuse blocks or physical fuse replacement, this module utilizes smart circuitry to protect against short circuits and overloads. Each channel provides diagnostic feedback, allowing the controller to identify and report fault conditions at the point level, significantly reducing mean time to repair (MTTR).
