Allen-Bradley 1756-OV32E
The 1756-OV32E provides 32 sinking DC output points arranged in two groups. Its electronically fused output design supports discrete control functions in ControlLogix chassis-based automation systems.
Module Overview
Technical Specifications
Current ratings are temperature dependent. At 60°C, the maximum continuous current is 0.35 A per point, 5 A per group and 10 A per module. Confirm the complete load profile and wiring design against Rockwell Automation technical documentation before commissioning.
Installation & System Integration
Chassis and Terminal Interface
The module is designed for installation in a ControlLogix chassis. The specified removable terminal block options are 1756-TBCH and 1756-TBS6H. Confirm the installed terminal-block type and field wiring arrangement before installation.
Field Wiring Arrangement
Use the manufacturer's wiring diagram for the DC supply and return connections. Follow the terminal assignments and wiring instructions in the module installation documentation.
Configuration Reference
The module uses electronic, software-configurable keying. Verify the selected module identity and configuration in the ControlLogix project before placing the system into operation.
Installation Precaution
Installation, wiring and maintenance should be performed by qualified personnel. Follow the manufacturer's instructions and applicable electrical codes, including relevant hazardous-location precautions.
Application & Fault Scenarios
Typical System Use
The 1756-OV32E is used in ControlLogix systems requiring multiple 10–30 V DC sinking output points. It can switch compatible DC field loads within machine sequencing, equipment interlocks and discrete process-control operations. The connected devices depend on the electrical design of the installation.
Maintenance and Downtime Concerns
Maintenance teams may search for this module when output channels stop switching, a field output becomes unavailable, or a suspected module fault interrupts an output group. If affected outputs control essential machine operations, production sequences may stop while the fault is diagnosed and the module is replaced.

Frequently Asked Questions
1. What type of module is the Allen-Bradley 1756-OV32E?
It is a ControlLogix 32-point DC sinking output module with electronically fused outputs. Its operating voltage range is 10–30 V DC.
2. How are the 32 output points arranged?
The module has two output groups, each containing 16 points. Electronic fusing is provided per group.
3. What is the maximum continuous output current?
The maximum current per point is 0.5 A at 50°C and 0.35 A at 60°C. Group and module current limits must also be observed.
4. Which removable terminal blocks are specified for the 1756-OV32E?
Rockwell Automation specifies the 1756-TBCH and 1756-TBS6H removable terminal blocks. Confirm the installed terminal block and wiring arrangement before replacement.
5. What should be checked when sourcing a replacement 1756-OV32E?
Confirm the complete catalog number, module condition, terminal-block arrangement, ControlLogix chassis requirements and the electrical ratings of the connected field loads. Compare the existing system configuration with the manufacturer's documentation.
