Product Overview

Allen-Bradley 1336F-BRF100-AE-EN Ruggedized VFD Drive Module: Industrial Resilience for Harsh Environments

The Allen-Bradley 1336F-BRF100-AE-EN is a 100HP, 460V AC Variable Frequency Drive from the renowned 1336 FORCE series — engineered to deliver uncompromising performance 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 purpose-built to sustain continuous, reliable motor control where lesser equipment fails.

Designed for critical infrastructure applications, the 1336F-BRF100-AE-EN provides precise speed and torque regulation for large AC induction motors, making it an essential component in process-critical systems where unplanned downtime carries severe operational and safety consequences. Its robust power electronics, advanced thermal management architecture, and EMI-hardened design ensure stable operation even in environments characterized by electrical noise, voltage transients, and fluctuating load demands.

Comprehensive Protection Solutions

The 1336F-BRF100-AE-EN is rarely deployed in isolation — it operates as a critical node within a broader automation and safety architecture. In a typical heavy-industry control cabinet, this drive works in concert with an Allen-Bradley 1756-L71 ControlLogix CPU to execute coordinated motion and process logic, while 1756-IB16 digital input modules and 1756-OB16 digital output modules handle field-level I/O for sensors, actuators, and interlocks. For distributed I/O in remote panel locations, the 1734 POINT I/O system provides modular, DIN-rail-mounted expansion that integrates seamlessly over DeviceNet — the same communication protocol supported by the EN variant of this drive.

Power quality and protection are equally critical. The Allen-Bradley 1321-3R75-B line reactor is commonly installed upstream of the 1336F-BRF100-AE-EN to suppress voltage spikes and reduce harmonic distortion on the supply bus, extending drive service life in environments with poor power quality. Downstream motor protection is reinforced by Allen-Bradley E300 electronic overload relays, which provide precise thermal modeling and ground-fault detection for the driven motor. For safety-rated applications requiring SIL 2 or PLd compliance, the Allen-Bradley 440C Guardmaster safety relay provides hardwired emergency-stop and safety-gate monitoring that integrates with the drive’s enable input circuit.

Communication integrity across the control network is maintained by the 1756-ENBT EtherNet/IP bridge module, which bridges the ControlLogix backplane to the plant Ethernet backbone, enabling remote diagnostics and parameter monitoring of the 1336F-BRF100-AE-EN via RSLogix 5000 or Studio 5000. Terminal connectivity within the control cabinet is standardized using Allen-Bradley 1492 IEC terminal blocks, which provide reliable, vibration-resistant wiring terminations rated for the current levels associated with 100HP drive installations.

Application in Critical Infrastructure

In oil and gas upstream operations, the 1336F-BRF100-AE-EN drives high-capacity pump motors on crude transfer and injection systems, where variable flow demand requires precise speed control and the drive must tolerate ambient temperatures exceeding 45°C alongside persistent hydrocarbon vapor contamination. Its robust thermal design and sealed power section make it a proven choice for enclosed wellhead and pipeline pump stations.

In underground mining, this drive controls ventilation fan motors and conveyor belt drives in environments characterized by coal dust, high humidity, and continuous mechanical vibration. The drive’s sensorless vector control capability ensures stable torque delivery even under rapidly changing load conditions — critical for preventing belt slip on inclined conveyors carrying ore loads.

In municipal water treatment and pumping stations, the 1336F-BRF100-AE-EN regulates centrifugal pump speed to match real-time flow demand, eliminating the energy waste and mechanical stress of throttle-valve control. Its DeviceNet communication interface allows seamless integration with SCADA systems for remote monitoring, alarm management, and predictive maintenance scheduling.

In metallurgical and steel mill applications, the drive manages rolling mill auxiliary motors and cooling system pumps in environments with extreme thermal cycling, heavy electromagnetic interference from arc furnaces, and airborne metallic particulate. The drive’s EMI-hardened design and compatibility with external input line reactors make it well-suited for these electrically hostile conditions.

In power generation facilities — including thermal, hydro, and co-generation plants — the 1336F-BRF100-AE-EN controls boiler feed pump auxiliaries, cooling tower fans, and fuel handling conveyors, where continuous 24/7 operation and zero-tolerance for unplanned trips are non-negotiable operational requirements.

Security & Quality FAQ

Q1: What does the 12-month warranty cover, and how is it enforced?
Every 1336F-BRF100-AE-EN unit shipped by TOPNLMS carries a 12-month warranty from the date of shipment. Coverage includes manufacturing defects, component failures under normal operating conditions, and firmware-related malfunctions. In the event of a warranty claim, we provide RMA processing, technical diagnosis, and replacement or repair at no additional cost. Our warranty terms are documented and provided with each shipment.

Q2: How is each unit tested before shipment?
All drives undergo pre-shipment functional verification including power-on self-test, parameter integrity check, and communication port validation. Units sourced from original manufacturer channels are cross-referenced against Allen-Bradley factory documentation to confirm authenticity and revision level. Visual inspection for physical damage, connector integrity, and label authenticity is performed as standard procedure before packaging.

Q3: Is the 1336F-BRF100-AE-EN compatible with my existing ControlLogix or SLC 500 system?
Yes. The EN (Enhanced) variant supports DeviceNet and DH-485 communication, making it directly compatible with Allen-Bradley ControlLogix, CompactLogix, SLC 500, and PLC-5 platforms. Parameter configuration is performed via DriveExplorer or RSLogix software. If you require confirmation of compatibility with a specific system architecture or firmware revision, our technical team can assist prior to purchase.

Q4: Can TOPNLMS support long-term supply and replacement for discontinued or hard-to-source 1336 FORCE drives?
Yes. The 1336 FORCE series has reached end-of-life status with the OEM, making reliable aftermarket sourcing critical for facilities that cannot immediately migrate to newer platforms such as the PowerFlex 700 or PowerFlex 755. TOPNLMS maintains inventory of 1336 FORCE series drives and modules specifically to support legacy system maintenance, emergency replacement, and planned lifecycle extension programs. We can provide lead-time commitments and volume pricing for facilities managing multi-unit installed bases.
