Product Details

1336S-MCB-SPI 74100-071-51 Product Description

The Allen-Bradley 1336S-MCB-SPI 74100-071-51 is the main control board at the heart of the 1336 PLUS AC drive, serving as the primary signal processing and command execution layer within a broader Rockwell Automation control architecture. Its SPI communication interface enables tight synchronization between the drive's internal logic and upstream control devices, making it a foundational component in multi-axis and multi-drive deployments.

In a complete 1336 PLUS drive system, this control board coordinates directly with the 1336-GM1 or 1336-GM2 gate driver boards, which translate the control board's PWM commands into IGBT switching signals across the power stage. The board also interfaces with the 1336-PB series power supply boards that provide regulated logic voltages, ensuring stable operation even under fluctuating line conditions. For applications requiring remote I/O expansion, the 1336S-MCB-SPI integrates with Allen-Bradley 1771 I/O modules via the PLC backplane, allowing analog and digital process signals to be routed directly into the drive's speed and torque reference inputs.

At the network layer, the control board supports integration with Allen-Bradley 1336-GM-SCANport adapter modules, enabling the drive to participate in DeviceNet or DH+ communication networks alongside PLC-5 or SLC 500 processors. This architecture allows centralized supervisory control from a Rockwell RSLogix 5 or RSLogix 500 programming environment, with the 1336S-MCB-SPI executing speed references, ramp profiles, and fault responses in real time. For HMI integration, the drive can be monitored and commanded through Allen-Bradley PanelView 550 or PanelView 900 terminals connected via DH-485 or DH+ links, providing operators with live drive status, fault codes, and parameter access without requiring direct drive panel interaction.

In redundant or high-availability architectures, the 1336S-MCB-SPI supports hot-standby configurations when paired with 1336-MOD-SCANport redundancy modules, ensuring that a control board fault does not result in unplanned process downtime. The board's diagnostic registers are accessible via the SCANport interface, allowing maintenance teams to retrieve fault history, operating hours, and thermal status data remotely — reducing mean time to repair and supporting predictive maintenance programs. For power distribution, the drive system typically operates alongside Allen-Bradley 1494 disconnect switches and 1492 terminal block assemblies, which provide safe isolation points and structured wiring for field commissioning and periodic maintenance.

The 1336S-MCB-SPI 74100-071-51 control board is deployed across a wide range of industrial sectors where the 1336 PLUS drive platform remains the standard for variable-speed AC motor control. In manufacturing and assembly lines, the board enables precise conveyor speed regulation, coordinating with upstream PLC logic to synchronize product flow across multi-station production cells. In water and wastewater treatment facilities, it governs pump and blower drives, maintaining consistent flow rates and pressure profiles while supporting remote SCADA monitoring via DH+ or DeviceNet networks.

In oil, gas, and petrochemical processing, the 1336 PLUS drive with this control board manages compressor and agitator motors in hazardous-area control panels, where signal integrity and fault diagnostics are critical to process safety. Mining and mineral processing operations rely on the board's robust signal processing to control crusher drives, conveyor systems, and slurry pumps under high-vibration, high-dust conditions. In power generation and utilities, the board supports fan and pump drives in auxiliary systems, where long-term reliability and parts availability are essential for planned maintenance cycles.

For packaging and material handling applications, the 1336S-MCB-SPI enables multi-drive coordination across palletizing, wrapping, and sorting systems, with each drive receiving synchronized speed references from a central PLC. In metallurgical and steel processing plants, the board controls rolling mill and cooling bed drives, where precise torque and speed response directly affect product quality. Across all these applications, the 1336S-MCB-SPI 74100-071-51 delivers consistent control performance, supported by in-stock availability, pre-shipment functional testing, and a 12-Month Warranty.

Q1: Is the 1336S-MCB-SPI 74100-071-51 compatible with both 1336 PLUS and 1336 PLUS II drive frames? The 1336S-MCB-SPI 74100-071-51 is designed for the Allen-Bradley 1336 PLUS series. Compatibility with 1336 PLUS II frames depends on the specific firmware revision and hardware configuration of the target drive. We recommend verifying the drive's catalog number and firmware version before ordering. Our technical team can assist with cross-referencing to confirm fitment for your specific drive frame and application.

Q2: How does this control board integrate with existing Rockwell Automation PLC and network architectures? The 1336S-MCB-SPI interfaces with Rockwell Automation control systems via SCANport adapter modules, supporting DeviceNet, DH+, and DH-485 communication protocols. This allows the drive to receive speed and torque references from PLC-5, SLC 500, or ControlLogix processors and report drive status back to the supervisory control layer. No additional hardware modifications to the PLC backplane are required — the SCANport adapter plugs directly into the drive's communication port, enabling rapid network integration during commissioning.

Q3: What does the 12-Month Warranty cover, and what is the typical lead time for this part? The 12-Month Warranty covers full functional performance of the 1336S-MCB-SPI 74100-071-51 from the date of shipment, including defects in materials and workmanship under normal operating conditions. Each unit undergoes pre-shipment functional testing to verify signal integrity, communication interface operation, and board-level electrical parameters. This part is maintained in stock to support urgent maintenance and planned replacement programs, with standard lead times of 1–5 business days for most destinations.
