1756-OB16E Allen-Bradley ControlLogix 16-Point DC Output Module — Industrial-Grade Original Spare Parts

As a procurement manager sourcing critical spare parts for continuous-process facilities, you need components that arrive verified, documented, and ready to install. The Allen-Bradley 1756-OB16E is a 16-point electronically fused DC digital output module purpose-built for the ControlLogix PLC System platform. 100% Brand New and Factory Sealed, every unit of the 1756-OB16E we supply is sourced directly from authorized distribution channels, ensuring full traceability and compliance with your plant’s quality standards. This Original New Control Module eliminates the risk of counterfeit components that can compromise uptime in safety-critical environments.

Industrial Automation facilities across Oil & Gas, Power Generation, and Automotive Manufacturing depend on Spare Parts like the 1756-OB16E to maintain deterministic output switching for solenoids, motor starters, and indicator arrays. Whether you are managing an aging ControlLogix chassis or expanding a greenfield PLC System, this module integrates seamlessly into any 1756 backplane without firmware conflicts. Its robust electronic fusing architecture replaces traditional glass fuses, reducing maintenance overhead and delivering precision fault isolation at the channel level.

With fast global logistics, a 1-year warranty, and dedicated technical support for EOL legacy systems, sourcing the 1756-OB16E through our platform means your production line stays running — not waiting.

Typical Application Scenarios

✅ Oil & Gas Upstream & Midstream: Pipeline valve sequencing demands fail-safe DC output control. The 1756-OB16E’s per-channel electronic fusing prevents a single valve fault from cascading across the output bank, protecting both equipment and personnel.

Power Plants & Utilities: Turbine auxiliary control panels require heavy-duty, reliable switching at 24V DC. This module’s 2A-per-point rating and 10-31.2V DC operating range accommodate the wide voltage fluctuations common in power generation environments.

✅ Automotive Assembly Lines: Robotic cell coordination and conveyor actuator control benefit from the module’s 1ms typical ON/OFF response time, enabling precise, high-speed sequencing without jitter.

✅ Water & Wastewater Treatment: Pump and valve management in wet environments requires robust isolation. The 1756-OB16E provides 50V continuous channel-to-backplane isolation, protecting the PLC System backplane from field-side transients.

✅ Packaging & Material Handling: High-cycle solenoid valve applications demand modules that can sustain continuous 2A loads without thermal derating. This Control Module is engineered for exactly that duty cycle.

FAQ — Frequently Asked Questions

Q1: What is the price of the 1756-OB16E, and do you offer volume discounts?
A: Our listed price reflects current market availability. For orders of 5 units or more, contact sale@ninermas.com for a tiered volume discount quotation. Prices are subject to change based on global supply chain conditions — locking in your order early is recommended for budget-sensitive projects.

Q2: What is the lead time for the Allen-Bradley 1756-OB16E?
A: In-stock units ship within 1-2 business days globally. For large-quantity orders or specific date code requirements, lead time is typically 3-7 business days. Contact us with your required delivery date and we will confirm availability immediately.

Q3: Can you provide a Certificate of Origin and manufacturer datasheet for the 1756-OB16E?
A: Yes. All Original New units are supplied with a Certificate of Origin (USA), manufacturer’s datasheet (Rockwell Automation Publication 1756-TD001), and a quality inspection report. These documents are standard with every shipment to support your incoming goods inspection process.

Q4: Is this module compatible with all ControlLogix chassis sizes?
A: The 1756-OB16E is compatible with all standard 1756 ControlLogix chassis (4, 7, 10, 13, and 17-slot). It occupies one slot and communicates over the ControlLogix backplane. Verify your chassis power supply budget against the module’s 150mA @ 5V DC draw before installation.

Q5: How do I confirm this is a genuine Allen-Bradley 1756-OB16E and not a counterfeit?
A: Every unit we supply is 100% Original and Brand New, sourced from authorized distribution. We provide the manufacturer’s holographic label, serial number, and date code for verification. Customers may also request a pre-shipment inspection report.

Q6: Does the 1756-OB16E support online module replacement (OMR)?
A: Yes. With the appropriate ControlLogix firmware version and Studio 5000 project configuration, the 1756-OB16E supports online module replacement — allowing field technicians to swap the module without halting the controller or interrupting other I/O on the backplane.
