Allen-Bradley 1336F-BRF100-AA-EN Braking Resistor for 1336 PLUS II

Allen-Bradley 1336F-BRF100-AA-EN Braking Resistor for 1336 PLUS II

The Allen-Bradley 1336F-BRF100-AA-EN is a dedicated braking resistor module engineered for seamless integration within the 1336 PLUS II AC drive platform. In modern industrial control system architecture, dynamic braking performance is not an isolated function — it is a critical element that governs the stability, safety, and responsiveness of the entire drive-motor-load chain. This module provides the resistive load path required to dissipate regenerative energy during deceleration cycles, protecting the DC bus from overvoltage faults and enabling precise, repeatable stopping performance across demanding process environments.

Designed for system integration within the Rockwell Automation 1336 PLUS II ecosystem, the 1336F-BRF100-AA-EN is rated at 100% braking duty cycle capacity, making it suitable for high-inertia load applications including centrifuges, hoists, winders, and high-speed conveyors. Its architecture-ready design ensures compatibility with the full range of 1336 PLUS II drive frames, supporting system engineers in building cohesive, scalable automation solutions without the need for third-party braking hardware.

System Compatibility Notes

The 1336F-BRF100-AA-EN does not operate in isolation. Its value is fully realized when considered within the broader architecture of a 1336 PLUS II-based control system. At the drive layer, the 1336 PLUS II drive unit — such as the 1336F-BRF075-AA-EN or adjacent frame variants — manages motor speed, torque, and direction through closed-loop vector or V/Hz control. The braking resistor module connects directly to the drive’s internal braking transistor output, forming a low-impedance discharge path for regenerative DC bus energy.

At the power layer, the system typically incorporates a 1336-PB series line filter and an appropriate 1321-3R line reactor to condition incoming AC power and reduce harmonic distortion. These upstream components protect the drive from line transients and ensure stable rectifier operation — a prerequisite for reliable braking performance. The 1336F-BRF100-AA-EN complements this power conditioning architecture by managing the downstream energy that would otherwise stress the DC bus capacitor bank.

At the control and I/O layer, a 1756-L series ControlLogix CPU or a 1769-L series CompactLogix controller typically serves as the supervisory control platform, issuing speed reference and deceleration ramp commands to the 1336 PLUS II drive via a 1203-USB or 1203-GU6 communication adapter supporting DeviceNet or Remote I/O protocols. The braking resistor module ensures that aggressive deceleration ramps programmed at the controller level can be executed without triggering DC bus overvoltage faults — a common failure mode in high-inertia applications without adequate braking capacity.

At the network layer, 1756-ENBT or 1756-EN2T EtherNet/IP communication modules within the ControlLogix chassis provide supervisory SCADA connectivity, enabling real-time monitoring of drive status, fault codes, and energy consumption. The braking resistor’s role in preventing nuisance faults directly contributes to higher system uptime and more reliable data continuity at the network layer.

At the human-machine interface layer, a 2711P PanelView Plus terminal provides operators with drive status visualization, fault history, and manual override capability. Reliable braking performance — enabled by the 1336F-BRF100-AA-EN — reduces the frequency of fault acknowledgment events that operators must manage, improving overall HMI workflow efficiency.

At the execution layer, motors paired with the 1336 PLUS II drive — including standard NEMA frame induction motors and inverter-duty motors — benefit from the smooth, controlled deceleration that the braking resistor enables. In applications such as packaging lines, material handling conveyors, and pump systems, precise stopping reduces mechanical wear on couplings, gearboxes, and braking mechanisms, extending the service life of the entire drivetrain.

Industrial Application Notes

Manufacturing & Packaging Lines: In high-speed packaging and assembly lines, frequent start-stop cycles generate significant regenerative energy. The 1336F-BRF100-AA-EN absorbs this energy reliably, enabling aggressive deceleration ramps without drive faults, improving throughput and reducing downtime.

Power Generation & Utilities: In power plant auxiliary systems — including cooling tower fans, boiler feed pumps, and induced draft fans — the braking resistor module supports controlled shutdown sequences, ensuring that drive systems respond predictably during emergency stop events and planned maintenance outages.

Petrochemical & Process Industries: Compressor and pump drive systems in petrochemical facilities require precise speed control and safe deceleration. The 1336F-BRF100-AA-EN provides the braking capacity needed to meet process safety requirements without relying on mechanical braking systems that require frequent maintenance.

Water & Wastewater Treatment: Variable-speed pump drives in water treatment plants benefit from smooth deceleration to prevent water hammer effects in pipeline systems. The braking resistor module enables the 1336 PLUS II drive to execute controlled ramp-down sequences that protect both the drive and the hydraulic infrastructure.

Mining & Metals Processing: Conveyor drives, crusher drives, and hoist systems in mining operations involve high-inertia loads that generate substantial regenerative energy during deceleration. The 100% duty cycle rating of the 1336F-BRF100-AA-EN makes it well-suited for these demanding continuous-duty braking applications.

Product Compatibility FAQ

Q1: Is the 1336F-BRF100-AA-EN compatible with all frame sizes of the 1336 PLUS II drive series?
The 1336F-BRF100-AA-EN is designed for specific frame sizes within the 1336 PLUS II platform. Compatibility is determined by the drive’s horsepower rating and internal braking transistor specification. Engineers should verify the drive’s catalog number and cross-reference the 1336 PLUS II product selection guide to confirm that the BRF100 resistor module matches the drive’s braking transistor output rating. For adjacent power ranges, Allen-Bradley offers the BRF050 and BRF200 variants to cover the full drive family.

Q2: Can this braking resistor module be used in a redundant drive architecture?
In redundant drive configurations — where two 1336 PLUS II drives are deployed in a hot-standby or duty-standby arrangement — each drive unit requires its own dedicated braking resistor module. The 1336F-BRF100-AA-EN cannot be shared between drives due to the direct DC bus connection architecture. System designers should specify one BRF100 module per drive in redundant configurations, ensuring that the standby drive is equally capable of executing controlled deceleration upon switchover.

Q3: What does the warranty terms confirmed during quotation cover, and how does it support long-term maintenance planning?
The warranty terms confirmed during quotation covers manufacturing defects and electrical failures under normal operating conditions, including resistor element failure, terminal connection defects, and enclosure integrity issues. For maintenance engineers, this warranty provides a defined baseline for spare parts planning — allowing facilities to schedule replacement evaluations at the 12-month mark as part of a preventive maintenance program. ZYPLC maintains RFQ-confirmed sourcing of the 1336F-BRF100-AA-EN to support rapid replacement needs, minimizing unplanned downtime in production-critical environments.
