Allen-Bradley 1336F-BRF200-AA-EN Ruggedized AC Drive for Harsh Environments

Product Overview

Allen-Bradley 1336F-BRF200-AA-EN Ruggedized AC Drive for Harsh Environments

The Allen-Bradley 1336F-BRF200-AA-EN is a 200HP Flux Vector AC Drive from the renowned 1336 FORCE series, engineered by Rockwell Automation to deliver uncompromising performance in the most demanding industrial environments. Designed for continuous-duty operation in high-temperature, high-humidity, dust-laden, and vibration-intensive facilities, this drive is a cornerstone component for engineers and procurement specialists who cannot afford unplanned downtime. Whether deployed in a steel mill, offshore platform, water treatment facility, or chemical processing plant, the 1336F-BRF200-AA-EN provides the torque control precision and environmental resilience that mission-critical applications demand.

Built on Rockwell Automation’s proven 1336 FORCE architecture, this drive delivers closed-loop flux vector control with exceptional low-speed torque performance — a critical requirement for heavy-load starting in mining conveyors, large pump stations, and compressor drives. Its robust power section is rated for 200HP output, making it suitable for high-inertia loads where lesser drives fail prematurely. The drive’s internal thermal management system, combined with its conformal-coated control boards, ensures reliable operation even in environments with aggressive airborne contaminants, salt spray, or condensing humidity.

The 1336F-BRF200-AA-EN integrates seamlessly into Rockwell Automation control architectures. It communicates natively with Allen-Bradley PLCs — including the ControlLogix 1756 series and CompactLogix 1769 series — via Remote I/O (RIO) and can be adapted for DeviceNet or DH+ communication using the appropriate communication adapter modules. This native compatibility eliminates integration risk and reduces commissioning time significantly on brownfield projects where existing Rockwell infrastructure is already in place.

Comprehensive Protection Solutions

In a fully integrated Rockwell Automation control cabinet, the 1336F-BRF200-AA-EN operates as the primary motion control element within a layered protection architecture. Upstream, a properly sized Allen-Bradley 1321 line reactor conditions incoming power and suppresses voltage transients that could otherwise stress the drive’s input rectifier — a critical protection measure in facilities with heavy switching loads or weak grid infrastructure. On the output side, a 1321 load reactor or dV/dt filter protects motor insulation from the steep voltage rise times inherent in PWM drive outputs, extending motor service life in long-cable installations.

The drive’s control section interfaces directly with Allen-Bradley 1756-IB16 digital input modules and 1756-OB16 digital output modules housed in a ControlLogix chassis, enabling real-time speed reference, fault status, and run/stop commands to be exchanged over the backplane without additional wiring. For analog speed reference, a 1756-IF8 analog input module provides the 4–20mA or 0–10V signal that the 1336F-BRF200-AA-EN accepts natively. Safety interlock circuits are typically implemented using Allen-Bradley 440R Guardmaster safety relays, which monitor E-stop circuits and gate the drive’s enable input to ensure SIL-compliant safe torque-off behavior during emergency conditions.

Power distribution within the control cabinet is managed by Allen-Bradley 1606-XLP series industrial power supplies, which provide stable 24VDC control voltage to the drive’s logic circuits, I/O modules, and HMI panels. Terminal connections between field wiring and the control system are made through Allen-Bradley 1492 series terminal blocks, which provide reliable, vibration-resistant termination points suitable for the mechanical stress of heavy industrial environments. For facilities requiring network-level diagnostics, a 1336-GM6 DeviceNet communication adapter can be fitted to the drive, enabling integration with a DeviceNet scanner module such as the 1756-DNB for real-time parameter monitoring and fault logging via RSLogix 5000 or Studio 5000 Logix Designer.

Application in Critical Infrastructure

The 1336F-BRF200-AA-EN has established a strong service record across the most demanding sectors of critical infrastructure. In oil and gas upstream operations, it controls large submersible pump drives and gas compression skids where continuous, unattended operation is mandatory and any drive failure translates directly into lost production revenue. Its ability to maintain precise torque control at low speeds makes it particularly valuable for soft-starting large centrifugal pumps in pipeline booster stations, eliminating water hammer and reducing mechanical stress on pump seals and impellers.

In mining and mineral processing, the drive manages conveyor belt systems, ball mill drives, and slurry pump stations where the combination of heavy dust, vibration, and high ambient temperatures creates an extremely hostile operating environment. The conformal-coated control boards and robust power section of the 1336F-BRF200-AA-EN provide the environmental resilience required to sustain reliable operation between scheduled maintenance intervals in these conditions. Power generation and utilities operators deploy this drive in cooling water pump systems, forced-draft fan applications, and boiler feed pump drives, where variable-speed control delivers significant energy savings compared to throttle-valve flow control while maintaining the reliability standards required for continuous baseload generation.

In metals and heavy manufacturing — steel rolling mills, aluminum smelters, and forge shops — the drive’s flux vector control capability provides the precise torque response needed for tension control in rolling lines and positioning accuracy in transfer car applications. Water and wastewater treatment authorities rely on the 1336 FORCE platform for aeration blower drives, sludge pump stations, and filter backwash pump systems, where the combination of energy efficiency, reliability, and compatibility with existing Rockwell SCADA infrastructure makes it the preferred choice for both new installations and aging-infrastructure replacement projects.

Security & Quality FAQ

Q1: What warranty coverage is provided with the 1336F-BRF200-AA-EN?
Every unit shipped by TOPNLMS carries a 12-month warranty covering defects in materials and workmanship. Prior to shipment, each drive undergoes a multi-point inspection protocol including visual inspection, power-on functional verification, and output parameter testing. Units that do not meet our quality benchmarks are not shipped. Warranty claims are handled directly by our technical team with a commitment to rapid resolution — replacement units are dispatched from stock wherever possible to minimize your downtime.

Q2: How do I verify compatibility with my existing Allen-Bradley PLC or DCS system?
The 1336F-BRF200-AA-EN is fully compatible with the Allen-Bradley SLC 500, PLC-5, ControlLogix 1756, and CompactLogix 1769 families via Remote I/O. For DeviceNet or DH+ integration, the appropriate 1336-GM communication adapter module is required. Our technical team can review your existing system architecture and confirm compatibility before you commit to purchase — simply provide your PLC model, firmware version, and communication network topology.

Q3: Is long-term supply availability guaranteed for this model?
Yes. TOPNLMS maintains dedicated inventory of 1336 FORCE series drives, including the 1336F-BRF200-AA-EN, specifically to support customers operating legacy Rockwell Automation systems where OEM supply has been discontinued or lead times are extended. We source from verified channels and maintain stock levels to support both immediate replacement needs and planned maintenance programs. Customers with recurring demand can discuss scheduled supply agreements with our sales team.

Q4: What safety precautions should be observed when replacing a 1336F-BRF200-AA-EN in the field?
Field replacement must be performed by qualified electrical personnel following NFPA 70E arc flash safety procedures and local electrical codes. The drive must be fully de-energized and the DC bus discharged (minimum 5-minute wait after power removal) before any wiring or mechanical work is performed. Parameter backup via DriveExplorer or Studio 5000 Drive Executive software is strongly recommended before removal to facilitate rapid recommissioning of the replacement unit. TOPNLMS can provide parameter file templates and commissioning checklists upon request to support your maintenance team.
