Allen-Bradley 1336F-BRF100-AE-EN-HAS2-L6 Ruggedized AC Drive Module for Harsh Environments

Product Overview

Allen-Bradley 1336F-BRF100-AE-EN-HAS2-L6: Industrial Resilience for the Most Demanding Environments

The Allen-Bradley 1336F-BRF100-AE-EN-HAS2-L6 is a 100HP variable frequency drive (VFD) from Rockwell Automation’s proven 1336 FORCE series — engineered for continuous, reliable operation in the harshest 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 delivers the torque control precision and electromagnetic immunity that mission-critical processes demand.

Designed around a closed-loop flux vector control architecture, the 1336F-BRF100-AE-EN-HAS2-L6 provides exceptional dynamic response and speed regulation accuracy, making it the preferred choice for applications where process uptime is non-negotiable. Its robust power stage, combined with integrated EMI filtering and advanced thermal management, ensures stable output even under sustained full-load conditions in ambient temperatures up to 50°C.

Comprehensive Protection Solutions

The 1336F-BRF100-AE-EN-HAS2-L6 does not operate in isolation — it is a cornerstone component within a broader, integrated control architecture. In a typical heavy-industry control cabinet, this drive works in concert with Allen-Bradley 1756-L75 ControlLogix processors and 1756-IB16 digital input modules to execute precise motion sequences across multi-axis production lines. The EtherNet/IP communication interface (EN suffix) enables seamless integration with 1783-US8T Stratix 2000 managed switches, ensuring deterministic data exchange between the drive and the supervisory PLC layer without signal degradation in high-EMI environments.

For power conditioning and protection upstream of the drive, the 1321-3R75-C line reactor is commonly paired with this unit to suppress voltage spikes and reduce harmonic distortion on the supply bus — a critical safeguard in facilities where multiple large drives share a common power rail. On the output side, dynamic braking is handled via compatible braking resistor assemblies, enabling rapid deceleration of high-inertia loads such as centrifugal pumps, compressors, and conveyor systems without stressing the DC bus.

Within the same control cabinet, Allen-Bradley 1492-J series terminal blocks and 1492-CABLE series pre-wired I/O cables provide reliable, vibration-resistant signal termination between the drive’s I/O terminals and field instrumentation. Safety interlock circuits are typically implemented using Allen-Bradley MSR127RP safety relays or GuardLogix 1756-L73S safety controllers, which monitor drive fault outputs and initiate safe-state shutdowns in compliance with IEC 62061 SIL 2 requirements. For distributed I/O expansion in remote panel locations, 1734 POINT I/O modules over EtherNet/IP extend the control reach without additional cabling complexity.

Human-machine interface integration is typically achieved via PanelView Plus 7 (2711P series) terminals, which display real-time drive parameters — output frequency, motor current, fault codes, and energy consumption — giving operators immediate visibility into drive health during continuous production runs.

Application in Critical Infrastructure

In oil and gas upstream operations, the 1336F-BRF100-AE-EN-HAS2-L6 drives submersible pump motors and wellhead compressors where ambient temperatures fluctuate dramatically between day and night cycles, and where salt-laden air accelerates corrosion of unprotected electronics. Installed within NEMA 12 or NEMA 4X rated enclosures, this drive maintains full rated output without thermal derating, supporting uninterrupted extraction operations.

In underground mining, the drive controls ventilation fan motors and conveyor belt systems in environments characterized by coal dust, silica particulate, and persistent mechanical vibration from blasting and heavy equipment. Its robust power electronics and conformal-coated control boards resist particulate ingress and moisture condensation, reducing unplanned downtime in environments where maintenance access is costly and time-consuming.

At power generation facilities — including coal-fired, hydroelectric, and combined-cycle gas turbine plants — the 1336 FORCE series drives are deployed on boiler feed pumps, cooling tower fans, and induced draft fans. The drive’s closed-loop vector control maintains precise speed regulation under rapidly varying load conditions, directly contributing to plant efficiency and grid stability compliance.

In municipal water treatment and wastewater management, the 1336F-BRF100-AE-EN-HAS2-L6 manages aeration blowers and effluent pumps operating 24/7 in high-humidity, chemically aggressive atmospheres. The drive’s integrated PID control loop eliminates the need for external process controllers on simple pump applications, reducing panel complexity and potential failure points.

For metals and cement manufacturing, where kiln drives, rolling mill motors, and crusher drives demand maximum torque at low speeds, the flux vector control mode of the 1336 FORCE series delivers full rated torque from near-zero RPM — a capability that conventional V/Hz drives cannot match — ensuring smooth material processing without mechanical shock to gearboxes and couplings.

Security & Quality FAQ

Q1: What does the 12-month warranty cover for the 1336F-BRF100-AE-EN-HAS2-L6?
All units supplied by TOPNLMS carry a 12-month full functional warranty from the date of shipment. This covers verified manufacturing defects and functional failures under normal operating conditions. Each unit undergoes pre-shipment power-on testing and functional verification before dispatch. In the event of a warranty claim, TOPNLMS provides replacement or repair support with documented test reports.

Q2: How is each unit tested before shipment?
Every 1336F-BRF100-AE-EN-HAS2-L6 in our inventory is subject to a multi-point inspection protocol: visual inspection for physical integrity, power-on functional test confirming correct parameter initialization and communication response, and output voltage verification across all three phases. Units that do not pass all checkpoints are quarantined and not offered for sale. Test records are available upon request for quality-critical procurement processes.

Q3: Is this drive compatible with my existing Allen-Bradley PLC and network infrastructure?
Yes. The EN suffix confirms native EtherNet/IP support, enabling direct integration with ControlLogix, CompactLogix, and other Logix-family controllers via standard Add-On Instructions (AOIs) and pre-built drive faceplates in Studio 5000 Logix Designer. The drive is also backward-compatible with legacy SLC 500 and PLC-5 systems via DH+ or Remote I/O adapters. If you require compatibility confirmation for a specific system architecture, contact our technical team with your existing PLC model and network topology.

Q4: Can TOPNLMS support long-term supply continuity for this model?
Yes. TOPNLMS maintains dedicated inventory of 1336 FORCE series drives and associated spare parts to support customers with ongoing maintenance programs, planned shutdowns, and emergency replacement requirements. We understand that industrial facilities cannot afford extended lead times for critical drive components. Our procurement network ensures consistent availability of both current-production and legacy Allen-Bradley VFD models, with typical order fulfillment within 3–5 business days for in-stock units.
