Product Overview

Allen-Bradley 1336S-BRF10-AA-EN Ruggedized Variable Frequency Drive: Industrial Resilience for Harsh Environments

The Allen-Bradley 1336S-BRF10-AA-EN is a 10HP, 460VAC, DeviceNet-enabled AC variable frequency drive from Rockwell Automation’s proven 1336 PLUS series — engineered to deliver consistent, fault-tolerant motor control in the most demanding industrial environments. Whether deployed in high-temperature foundries, moisture-laden water treatment facilities, dust-heavy mining operations, or vibration-intensive heavy manufacturing lines, this drive is built to sustain continuous production without compromise.

At TOPNLMS, we stock the 1336S-BRF10-AA-EN as a verified, tested unit with a 12-month warranty, ready for immediate dispatch. Our inventory is maintained to support both planned maintenance schedules and emergency replacement scenarios — minimizing your plant downtime and protecting your capital investment.

Comprehensive Protection Solutions

The 1336S-BRF10-AA-EN does not operate in isolation — it is a critical node within a broader control architecture. In a typical industrial control cabinet, this drive interfaces directly with Allen-Bradley ControlLogix L6x or L7x series PLCs via a 1756-DNB DeviceNet Bridge Module, enabling real-time speed feedback, fault diagnostics, and remote parameter adjustment without interrupting production. The DeviceNet communication layer ensures deterministic data exchange even in environments with significant electromagnetic interference from welding equipment, large motors, or high-frequency switching power supplies.

For motor protection upstream, engineers commonly pair this drive with Allen-Bradley 1492 series terminal blocks and 700-series safety relays to create a coordinated motor starter and protection circuit. On the power conditioning side, a 1321-3R line reactor is frequently installed ahead of the drive to suppress voltage spikes and reduce harmonic distortion — extending the service life of both the drive and the connected motor in facilities with unstable grid power.

In distributed I/O architectures, the 1336S-BRF10-AA-EN works alongside 1734 POINT I/O modules and 1756 ControlLogix I/O cards to provide granular process feedback. Safety-critical installations may also incorporate Allen-Bradley GuardLogix safety controllers and 440C-CR30 safety relay modules to enforce SIL-rated emergency stop and safe torque-off functions — meeting IEC 62061 and ISO 13849 requirements in hazardous zones.

For facilities running Profibus or EtherNet/IP alongside DeviceNet, a 1788-EN2DN EtherNet/IP-to-DeviceNet linking device enables seamless protocol bridging, allowing the drive to be monitored and controlled from a unified SCADA or DCS platform without hardware replacement. This interoperability is especially valuable during phased modernization projects where legacy DeviceNet infrastructure must coexist with newer Ethernet-based control systems.

Application in Critical Infrastructure

In oil and gas upstream operations, the 1336S-BRF10-AA-EN is deployed to control pump motors on wellhead injection skids and pipeline booster stations. Its ability to maintain precise flow rates under variable load conditions — while communicating fault states back to a central ControlLogix PLC — makes it indispensable for unattended remote installations where manual intervention is costly and slow.

In mining and mineral processing, this drive manages conveyor belt motors, crusher feed systems, and slurry pump drives in environments characterized by extreme dust ingress, mechanical shock, and wide ambient temperature swings. Installed within sealed, climate-controlled control cabinets rated to NEMA 12 or IP54, the drive operates continuously across multi-shift production schedules with minimal maintenance intervention.

Within municipal water and wastewater treatment facilities, the 1336S-BRF10-AA-EN provides energy-efficient variable-speed control for centrifugal pumps and aeration blowers. Its DeviceNet interface allows plant operators to monitor motor current, output frequency, and fault history from a central SCADA workstation — enabling predictive maintenance strategies that reduce unplanned outages and extend equipment service intervals.

In metallurgical and steel production environments, where radiated heat, conductive dust, and high-current switching transients are constant challenges, this drive’s robust thermal management and EMI suppression capabilities allow it to sustain reliable operation on rolling mill auxiliary drives, cooling fan motors, and hydraulic pump systems — applications where an unexpected drive fault can halt an entire production line and trigger significant financial losses.

For power generation and substation auxiliary systems, the drive controls forced-draft fans, cooling water pumps, and lube oil pumps on turbine generator sets. Its compatibility with Allen-Bradley safety modules and hardwired interlock circuits ensures that motor control functions remain available even during partial control system failures — a critical requirement for grid-connected generation assets.

Security & Quality FAQ

Q1: What does the 12-month warranty cover for the 1336S-BRF10-AA-EN?
The 12-month warranty provided by TOPNLMS covers verified manufacturing defects and functional failures under normal operating conditions. Each unit undergoes pre-shipment functional testing — including power-on verification, communication port check, and parameter read/write validation — before dispatch. In the event of a warranty claim, we provide direct technical support and replacement coordination to minimize your downtime.

Q2: How do you verify compatibility with my existing Allen-Bradley control system?
The 1336S-BRF10-AA-EN is a standard 1336 PLUS series drive with a factory-configured DeviceNet communication option. It is compatible with any DeviceNet-capable Allen-Bradley PLC platform, including SLC 500, PLC-5, and ControlLogix systems using a 1756-DNB or equivalent scanner module. If you require confirmation for a specific firmware revision or network configuration, our technical team can review your system architecture before shipment.

Q3: Is long-term supply availability guaranteed for this model?
Yes. TOPNLMS maintains a dedicated inventory of 1336 PLUS series drives and associated spare parts to support customers with legacy Allen-Bradley installations. We understand that many critical infrastructure operators cannot migrate to newer drive platforms without significant re-engineering cost, and we are committed to providing reliable spare parts supply for the operational life of your installed base.

Q4: What is the typical lead time and shipping process?
In-stock units are dispatched within 1–3 business days of order confirmation. We ship internationally via DHL, FedEx, and UPS with full tracking and export documentation. For urgent replacement requirements, expedited shipping options are available. All units are packaged in anti-static, shock-resistant materials to protect sensitive drive electronics during transit.
