Product Overview

Allen-Bradley 1336F-BRF10-AA-EN Ruggedized VFD Module for Harsh Industrial Environments

The Allen-Bradley 1336F-BRF10-AA-EN is a ruggedized AC variable frequency drive from Rockwell Automation’s proven 1336 FLEX series, engineered to deliver precise motor speed control under the most demanding industrial conditions. Rated at 1HP (0.75 kW) with a 240V AC input and integrated EtherNet/IP communication capability, this drive is purpose-built for continuous-duty applications where uptime, electromagnetic resilience, and environmental durability are non-negotiable. Whether deployed on a high-speed packaging line, a chemical dosing pump, a conveyor system in a dusty cement plant, or a cooling fan in a high-temperature steel mill, the 1336F-BRF10-AA-EN delivers consistent, reliable performance where lesser drives fail.

Industrial environments impose relentless stress on control hardware. Ambient temperatures can swing from sub-zero cold starts to sustained 50°C heat in enclosed control cabinets. Humidity, condensation, airborne particulates, mechanical vibration from heavy machinery, and conducted or radiated electromagnetic interference from welding equipment, large motors, and switching power supplies all conspire to degrade drive performance and shorten service life. The 1336 FLEX platform was designed with these realities in mind, incorporating robust thermal management, wide input voltage tolerance, and a communication architecture that maintains network integrity even in electrically noisy environments.

The EtherNet/IP port on the 1336F-BRF10-AA-EN enables seamless integration into Rockwell Automation’s Integrated Architecture, allowing the drive to communicate directly with Allen-Bradley ControlLogix and CompactLogix PLCs via standard Ethernet infrastructure. This eliminates the need for dedicated DeviceNet or DH+ cabling in new installations and simplifies network topology in retrofit projects. Drive parameters, fault diagnostics, and real-time speed feedback are all accessible through RSLogix 5000 or Studio 5000 Logix Designer, giving maintenance engineers full visibility into drive health without leaving the control room.

In a typical control cabinet deployment, the 1336F-BRF10-AA-EN operates alongside complementary Allen-Bradley components including the 1336-MOD-L2 communication adapter, 1321-3R line reactors for harmonic mitigation, and 1336-BRF dynamic braking resistors for applications requiring rapid deceleration. The drive’s compact footprint makes it compatible with standard 1336 FLEX mounting hardware, and its parameter set is compatible with the 1336 PLUS II and 1336 IMPACT series, simplifying spare-parts standardization across mixed-drive installations. For distributed I/O expansion, the drive integrates cleanly with 1734 POINT I/O modules and 1756 ControlLogix I/O racks, supporting both local and remote I/O architectures.

In oil and gas upstream facilities, the 1336F-BRF10-AA-EN controls submersible pump motors and wellhead injection systems where unplanned downtime translates directly to lost production revenue. In water and wastewater treatment plants, it manages aeration blowers and sludge transfer pumps that must operate continuously across wide flow ranges to meet regulatory discharge standards. In mining operations, it drives conveyor belt motors and ventilation fans in environments saturated with coal dust, silica, and corrosive gases. In metallurgical plants, it controls cooling water pumps and fume extraction fans that protect both equipment and personnel in high-temperature, high-particulate atmospheres. Across all these sectors, the drive’s ability to maintain stable output frequency under fluctuating load conditions and its built-in motor protection functions — including overcurrent, overvoltage, undervoltage, and overtemperature trips — provide a critical layer of process safety.

For facilities operating Allen-Bradley safety architectures, the 1336F-BRF10-AA-EN pairs effectively with 440C Guardmaster safety relays and 1791DS CompactBlock Guard I/O safety modules to implement SIL 2-capable drive stop functions. When integrated with a 1769 CompactLogix safety controller, the drive can participate in a coordinated emergency stop (E-stop) network that meets IEC 62061 and ISO 13849 requirements for machinery safety. This makes it a viable choice not only for standard process control but also for safety-instrumented systems (SIS) in facilities governed by IEC 61511.

Comprehensive Protection Solutions

Reliable motor control in harsh environments demands more than a capable drive — it requires a coordinated ecosystem of protection, communication, and power-conditioning components working in concert. The 1336F-BRF10-AA-EN is designed to operate as the central motion-control element within a broader Allen-Bradley control architecture. Upstream of the drive, a 1321-3R line reactor attenuates voltage spikes and harmonic distortion generated by the facility’s power distribution network, protecting the drive’s input rectifier from premature failure. A 1336-BRF dynamic braking resistor module connects to the drive’s braking chopper circuit to dissipate regenerative energy during rapid motor deceleration, preventing DC bus overvoltage faults on applications with high-inertia loads such as centrifuges or large fans.

On the network side, the drive’s EtherNet/IP port connects to a Stratix 5700 managed industrial Ethernet switch, which provides VLAN segmentation, port-level security, and Quality of Service (QoS) prioritization to ensure drive command packets are never delayed by competing traffic from HMI systems or historian servers. For applications requiring local operator control, a 2711P PanelView Plus 7 HMI provides a touchscreen interface for speed reference entry, fault acknowledgment, and trend visualization without requiring a laptop or engineering workstation on the plant floor.

Power distribution to the drive and its associated control panel components — including 1606-XLP switched-mode power supplies for 24VDC control circuits, 700-HLT timing relays for sequencing logic, and 1492-J terminal blocks for field wiring termination — is protected by a 140M motor protection circuit breaker sized to the drive’s input current rating. This combination of upstream protection, network infrastructure, and downstream I/O creates a complete, validated control system architecture that minimizes both installation risk and long-term maintenance burden.

Application in Critical Infrastructure

In petroleum refining and petrochemical processing, the 1336F-BRF10-AA-EN controls cooling water circulation pumps, heat exchanger fans, and chemical injection metering pumps in environments where process uptime is measured in millions of dollars per hour. The drive’s wide input voltage tolerance accommodates the voltage fluctuations common in facilities served by dedicated substations or diesel generator backup power, ensuring the drive remains operational during grid disturbances that would trip less robust equipment.

In underground coal and hard-rock mining operations, the drive manages conveyor belt drives, dewatering pumps, and ventilation fan motors in atmospheres laden with coal dust, silica particulates, and methane. Its robust EMC filtering suppresses interference from high-power blasting circuits and diesel-electric locomotives that share the same power distribution infrastructure. Maintenance teams operating in these environments value the drive’s DriveExplorer-compatible parameter backup capability, which allows a replacement unit to be configured and commissioned in under 30 minutes using a pre-saved parameter file — a critical advantage when every hour of downtime has direct safety and production implications.

Municipal water and wastewater treatment authorities deploy the 1336F-BRF10-AA-EN on aeration blower motors, sludge recirculation pumps, and UV disinfection system drives where continuous operation is mandated by environmental compliance permits. The drive’s built-in PID control loop eliminates the need for a separate process controller on simple single-loop applications, reducing panel complexity and potential failure points. In power generation facilities — both thermal and hydroelectric — the drive controls auxiliary systems including cooling tower fans, lube oil pumps, and governor actuator motors, where its EtherNet/IP connectivity allows integration into plant-wide DCS systems from Emerson DeltaV or Honeywell Experion without requiring protocol conversion gateways.
