Allen-Bradley 1756-OV16E DC Fused Sinking Output Module – ControlLogix Series
When a critical output module fails on the plant floor, the consequences are immediate and costly: conveyor lines halt, robotic arms freeze mid-cycle, and production supervisors face unplanned downtime that can cost thousands of dollars per hour. In high-stakes discrete manufacturing environments — automotive assembly, food & beverage packaging, material handling — the output module is the final command link between the PLC and the physical world. Without a reliable, fuse-protected sinking output module, a single short circuit can cascade into a full line shutdown, damaging both equipment and delivery commitments.
The Allen-Bradley 1756-OV16E is Rockwell Automation’s answer to that challenge within the ControlLogix platform — one of the most widely deployed programmable automation controller (PAC) architectures in global discrete and process manufacturing. As a 16-point, DC fused sinking output module, the 1756-OV16E occupies a critical position in the ControlLogix 1756 I/O family: it delivers field-level output control with individual electronic fuse protection per output point, dramatically reducing fault propagation risk. Trusted by system integrators and OEMs across North America, Europe, and Asia-Pacific, this module is a cornerstone component in safety-conscious, high-availability control system designs.

Key Features & Benefits
- Individual Electronic Fuse Protection: Each of the 16 output points is independently fuse-protected, preventing a single field-side fault from disabling the entire module — a critical advantage in high-uptime environments.
- Sinking Output Architecture: Compatible with NPN-type field devices (sensors, solenoids, actuators), making it the standard choice for Asian and European machine builders using NPN wiring conventions.
- LED Diagnostics per Point: Real-time visual status for each output channel accelerates fault isolation during commissioning and maintenance, reducing MTTR (Mean Time to Repair).
- Hot-Swap Capable: Supports removal and insertion under power (RIUP) within the ControlLogix chassis, enabling module replacement without full system shutdown.
- Removable Terminal Block (RTB): Pre-wired RTBs can be swapped independently of the module, simplifying field replacement and reducing rewiring time.
- Compact 1-Slot Form Factor: Fits any standard 1756 ControlLogix chassis slot, maximizing I/O density in space-constrained panels.
Industry & Equipment Applications
- Automotive Manufacturing: Body welding lines, paint shop conveyors, assembly robot end-effector control

Frequently Asked Questions
Q: What is the difference between the 1756-OV16E and the 1756-OB16E?
A: Both are 16-point DC output modules for ControlLogix. The 1756-OV16E is a sinking (NPN) output module, meaning the load connects between the output terminal and the positive supply. The 1756-OB16E is a sourcing (PNP) output module. The choice depends on your field device wiring convention.
Q: Is the 1756-OV16E compatible with all ControlLogix chassis?
A: Yes. The 1756-OV16E fits any standard 1756 ControlLogix chassis (1756-A4 through 1756-A17) and is compatible with all ControlLogix controllers running RSLogix 5000 / Studio 5000 Logix Designer.
Q: Can this module be replaced while the system is running?
A: Yes. The 1756-OV16E supports Removal and Insertion Under Power (RIUP), allowing hot-swap replacement without shutting down the entire chassis — a key feature for high-availability production environments.
Q: What does “fused” mean in the context of this module?
A: “Fused” refers to individual electronic fuse protection on each output point. If an output is overloaded or short-circuited, only that point is disabled and flagged via LED — the remaining 15 outputs continue to operate normally. This significantly reduces fault impact compared to non-fused modules.
Q: Do you provide a certificate of conformance or test report?
A: Yes. Upon request, Konmask.com can provide inspection documentation, series/revision disclosure, and a functional test report for modules that have been bench-tested.
Q: What is the lead time for the 1756-OV16E?
A: Lead time depends on current stock levels. In-stock modules typically ship within 1–3 business days. For out-of-stock items, our sourcing team can usually locate and deliver within 7–15 business days. Contact us for real-time availability.
