Product Details

1336F-BRF100-AA-EN Product Description

The Allen-Bradley 1336F-BRF100-AA-EN is a dynamic braking resistor module engineered for seamless integration within the 1336 PLUS II AC drive platform — one of Rockwell Automation's most widely deployed variable frequency drive families across process and discrete manufacturing environments. Rather than functioning as a standalone accessory, this braking resistor is a critical energy management component within a layered control architecture, enabling controlled deceleration, regenerative energy absorption, and drive protection across demanding industrial cycles.

Within a complete 1336 PLUS II control architecture, the 1336F-BRF100-AA-EN operates in close coordination with the 1336 PLUS II main drive unit (such as the 1336F-BRF series frame variants), the 1336-MOD-L2E DeviceNet communication module for network-level diagnostics, and the 1336-GM1 gate module for IGBT switching coordination. The braking resistor dissipates DC bus overvoltage generated during motor deceleration, protecting the drive's internal capacitor bank and preventing overvoltage faults that would otherwise interrupt production cycles.

At the power layer, the 1336F-BRF100-AA-EN interfaces with the 1336-PB series power bridge and is typically installed alongside 1321-3R line reactors that condition incoming power and reduce harmonic distortion on the supply side. For applications requiring coordinated multi-axis deceleration — such as winding machines, hoists, or centrifuge systems — the braking resistor works in tandem with the 1336 PLUS II dynamic brake transistor option card, ensuring that braking energy is routed efficiently to the resistor bank rather than fed back into the DC bus.

At the I/O and control layer, the drive system integrates with 1756-IB16 ControlLogix digital input modules for speed reference and run/stop command signals, while 1756-OF8 analog output modules provide closed-loop speed feedback to the PLC. The 1756-L7x ControlLogix L7 series CPU serves as the supervisory controller, executing motion profiles and monitoring drive status via EtherNet/IP. For legacy installations, the 1747-L553 SLC 5/05 processor with DH+ or EtherNet/IP connectivity provides an alternative control backbone compatible with 1336 PLUS II drive architectures.

At the HMI layer, operators interact with the drive system through 2711P-T10C21D8S PanelView Plus 7 terminals, which display real-time drive status, braking duty cycle utilization, and fault history. The 1203-USB DriveExplorer USB adapter enables direct parameter upload/download and firmware management during commissioning and maintenance cycles, reducing engineering time during system integration.

For communication and network integration, the 1336 PLUS II platform supports 1336-GM6 EtherNet/IP communication adapters, enabling the drive — and by extension the braking resistor's operational status — to be monitored via Rockwell's FactoryTalk View SE SCADA platform. This Contextual Integration capability ensures that braking events, thermal overload conditions, and resistor duty cycle data are visible at the supervisory level, supporting predictive maintenance strategies and reducing unplanned downtime.

The 1336F-BRF100-AA-EN braking resistor is deployed across a broad spectrum of industrial sectors where controlled deceleration and regenerative energy management are critical to process integrity and equipment longevity.

In manufacturing and packaging lines, the braking resistor enables rapid, repeatable deceleration of conveyor drives and servo-adjacent AC drives, maintaining precise stopping positions without mechanical brake wear. In water and wastewater treatment facilities, pump and blower drives equipped with 1336 PLUS II units rely on dynamic braking to prevent water hammer during emergency stops and controlled shutdown sequences. In oil and gas and petrochemical applications, the resistor module supports compressor and pump drive systems where controlled deceleration is mandated by process safety requirements.

In mining and minerals processing, conveyor and crusher drives operating under high inertia loads generate significant regenerative energy during deceleration — the 1336F-BRF100-AA-EN safely dissipates this energy, protecting drive electronics and extending service intervals. In power generation and utilities, auxiliary drive systems for cooling fans, feedwater pumps, and induced draft fans benefit from the resistor's ability to handle high-duty braking cycles without thermal degradation. In marine and offshore environments, the module's robust construction supports deck machinery and winch drive applications where reliable braking performance is essential for operational safety.

Q1: Is the 1336F-BRF100-AA-EN compatible with all 1336 PLUS II drive frame sizes, and how is it wired into the DC bus? The 1336F-BRF100-AA-EN is specifically rated for F-frame 1336 PLUS II drives. It connects directly to the drive's DB+ and DB- terminals on the DC bus, with the dynamic brake transistor option card (if installed) controlling the switching duty cycle. Ensure that the resistor's continuous power rating matches the application's braking duty cycle requirements — consult the 1336 PLUS II User Manual (Publication 1336 PLUS-5.0) for frame-specific wiring diagrams and resistor selection tables.

Q2: Can this braking resistor be used in a multi-drive common bus architecture, and what are the thermal management considerations? In common DC bus configurations, dynamic braking resistors are typically connected at the bus level rather than per-drive. The 1336F-BRF100-AA-EN is designed for individual drive connection; for common bus applications, consult Rockwell Automation's common bus design guide. Thermal management requires adequate enclosure ventilation — the resistor generates heat proportional to braking duty cycle, and ambient temperature must remain within the 0°C to 50°C operating range. Forced air cooling or external heat sink mounting may be required for high-duty applications.

Q3: What does the 12-Month Warranty cover, and what is the typical lead time for in-stock units? All 1336F-BRF100-AA-EN units supplied by NANKMOS are covered by a 12-Month Warranty against manufacturing defects and functional failures under normal operating conditions. Each unit undergoes pre-shipment functional testing and electrical verification. In-stock units are typically dispatched within 2–5 business days globally.
