Product Details

1336-BDB-SP5C Product Description

The Allen-Bradley 1336-BDB-SP5C is a factory-engineered drive control board designed exclusively for the 1336 PLUS series of AC variable frequency drives. As a core component within Rockwell Automation's integrated drive architecture, this board governs the fundamental control logic, gate firing sequences, and feedback signal processing that determine drive performance across demanding industrial environments. Whether deployed in a new installation or as a precision replacement in an existing 1336 PLUS system, the 1336-BDB-SP5C restores full drive functionality while maintaining compatibility with the surrounding control architecture — from the PLC control layer down to the motor execution layer.

In modern industrial automation, a drive control board is far more than a circuit card. It is the intelligence layer that bridges the command signals from a programmable logic controller — such as the Allen-Bradley 1756-L73 ControlLogix CPU or the 1769-L33ER CompactLogix processor — with the power conversion hardware that drives motors, pumps, compressors, and conveyors. The 1336-BDB-SP5C performs this role with precision, processing analog and digital feedback signals, managing fault detection routines, and coordinating with the drive's power structure to deliver stable, repeatable motor control across the full speed range.

System architects integrating the 1336-BDB-SP5C into a broader automation platform will find it fully compatible with the 1336 PLUS drive's existing I/O interface structure. The board interfaces directly with the drive's internal communication bus, supporting parameter access and diagnostic readback through the 1336-GM1 or 1336-GM2 Human Interface Module. When paired with a 1203-GU6 DeviceNet communication adapter or a 1203-SSS SCANport adapter, the drive can be fully integrated into a DeviceNet or DH-485 network, enabling real-time speed reference, torque command, and fault status exchange with the supervisory control layer.

From a system redundancy and reliability perspective, the 1336-BDB-SP5C supports the drive's built-in fault logging and diagnostic capabilities. Maintenance engineers can retrieve fault codes, monitor DC bus voltage, track output current waveforms, and verify gate driver status — all critical functions for minimizing unplanned downtime in continuous process environments such as petrochemical refining, water treatment, mining conveyors, and steel rolling mills. The board's design also supports integration with external safety relay modules such as the Allen-Bradley 440R-N23132 Guardmaster relay, enabling safe torque-off and emergency stop functions compliant with IEC 62061 and ISO 13849 safety standards.

Power supply integrity is essential for stable drive control board operation. The 1336-BDB-SP5C relies on the 1336 PLUS drive's internal SMPS (switched-mode power supply) section, which in turn depends on clean incoming AC power. In installations where power quality is a concern, engineers typically deploy Allen-Bradley 1321-3R line reactors or 1321-M line filters upstream of the drive to suppress harmonic distortion and voltage transients that could otherwise stress the control board's logic circuits. For cabinet-level power distribution, the 1492-SP series supplementary protectors provide branch circuit protection that safeguards both the drive and its control electronics.

The 1336-BDB-SP5C is engineered for installation in standard NEMA 1 or NEMA 12 enclosures, consistent with the 1336 PLUS drive's environmental ratings. In applications requiring higher ingress protection — such as outdoor pump stations or washdown environments — the drive assembly is typically housed in a 1336 PLUS-compatible NEMA 4X enclosure with appropriate thermal management. The control board itself operates within the drive's specified ambient temperature range of 0°C to 50°C, with derating required above 40°C in high-density panel configurations.

For multi-drive installations on a common DC bus or in coordinated motion applications, the 1336-BDB-SP5C's gate control logic must be synchronized with the drive's power structure to prevent cross-conduction faults. System integrators working on coordinated drive systems — such as those using the 1336 PLUS in master-follower configurations for winder or unwinder applications — will find that the board's parameter structure supports ratio control, droop compensation, and torque-proving functions that are essential for web tension control and material handling precision.

Every 1336-BDB-SP5C unit supplied by NANKMOS undergoes a structured pre-shipment test protocol that includes power-on functional verification, gate driver signal integrity checks, analog I/O calibration verification, and fault memory clearance. Units are shipped with ESD-protective packaging and are accompanied by a test report confirming operational status. Stock is maintained in our warehouse to support urgent replacement requirements, with same-day dispatch available for in-stock units.

The 1336-BDB-SP5C operates as the intelligence core of the 1336 PLUS drive within a layered Rockwell Automation control architecture. At the control layer, Allen-Bradley 1756-L73 ControlLogix or 1769-L33ER CompactLogix CPUs issue speed and torque references via EtherNet/IP or DeviceNet, routed through 1203-GU6 or 1203-SSS SCANport communication adapters directly to the drive's control board. The 1336-GM1 or 1336-GM2 HMI module provides local parameter access and fault diagnostics at the drive panel level.

At the I/O layer, 1756-IB16 digital input modules and 1756-OF8 analog output modules in the ControlLogix chassis provide process feedback signals — speed references, torque limits, and enable commands — that the 1336-BDB-SP5C processes in real time. For power quality protection, 1321-3R line reactors and 1492-SP supplementary protectors are deployed upstream, while 440R-N23132 Guardmaster safety relays provide safe torque-off integration. In coordinated multi-drive systems, the 1336-BDB-SP5C's parameter structure supports master-follower ratio control alongside companion 1336 PLUS drives, enabling synchronized operation across winder, conveyor, and pump station applications.

The Allen-Bradley 1336-BDB-SP5C drive control board serves critical roles across a broad spectrum of industrial sectors. In manufacturing and automotive assembly, it controls conveyor belt drives, robotic transfer systems, and precision positioning axes where consistent speed regulation and fault transparency are essential for production continuity. In petrochemical and refining facilities, the board supports pump and compressor drives operating in hazardous area enclosures, where reliable gate firing logic and fault logging reduce unplanned shutdowns in continuous process streams.

In water and wastewater treatment plants, the 1336-BDB-SP5C enables variable-speed pump control that optimizes energy consumption across varying flow demand profiles, with DeviceNet integration providing SCADA-level visibility into drive status and energy metrics. Mining and mineral processing operations rely on the board's robust fault detection to protect high-inertia conveyor and crusher drives from overcurrent and overvoltage events. In steel and metals processing, the board's torque-proving and droop compensation capabilities support coordinated rolling mill drives where tension control is critical to product quality. Marine and offshore applications benefit from the board's compatibility with NEMA 4X enclosures and its ability to operate reliably in high-vibration, high-humidity environments.
