Description
Product Name: 1336-B003-EOD-FA2-L3-S1 Allen Braley I/O module
Product details:
The Allen-Bradley 1336-B003-EOD-FA2-L3-S1 is an adjustable frequency AC drive (Variable Frequency Drive or VFD) manufactured by Rockwell Automation. It is designed to control the speed and torque of three-phase industrial induction motors.
⚠️ Note on Lifecycle: The Bulletin 1336 series is a legacy/obsolete product line from Allen-Bradley. While it is highly reliable, it is primarily available today as used, refurbished, or surplus stock for maintaining existing industrial systems.

🔍 Part Number Breakdown (Suffix Features)
- B003: 3 Horsepower rating.
- EOD: Open-style enclosure (IP00) or specific frame configuration.
- FA2 / L3 / S1: These denote factory-installed options which typically include:
- Control Interface (L3): Specific control/voltage interface board (e.g., 24V DC or 115V AC digital/analog I/O).
- Human Interface Module (FA2/HIM): Door or panel-mounted keypad/display.
- Special Options (S1): Custom factory modifications, specific firmware, or communication ports.
📈 Key Advantages (Product Strengths)
- Proven Reliability: A classic “workhorse” of the automation industry, known for its heavy-duty design and long operational lifespan.
- Precise Motor Control: Smooth acceleration, deceleration, and speed regulation to reduce mechanical wear on belts, gears, and motors.
- Energy Savings: Significantly reduces power consumption by running motors at optimal speeds rather than full speed 100% of the time.
- Advanced Diagnostics: Classic onboard diagnostics to help pinpoint faults such as overvoltage, undervoltage, and overcurrent.
🏭 Industrial Applications
The 1336 series is used in traditional manufacturing and process industries to control:
- Conveyor Systems: Synchronizing speeds and controlling product flow.
- Fans and Blowers: Modulating airflow in HVAC systems and industrial ventilation.
- Pumps: Maintaining pressure or flow control in water treatment and hydraulic systems.
- Material Handling: Packaging lines, mixers, and small cranes.
⚠️ Important Precautions & Guidelines
🛠️ Installation & Safety
- High Voltage Hazard: The drive retains lethal voltage in its DC-bus capacitors even after the main power is disconnected. Wait at least 5 to 10 minutes after powering off before touching any internal terminals.
- Proper Grounding: Ensure system grounding complies with local electrical codes (such as NEC or IEC) to prevent electromagnetic interference (EMI) and electrical shock.
- Thermal Management: Because this unit is often an open-chassis model (
EOD), ensure it is mounted in a clean, dry, well-ventilated control cabinet to avoid overheating.
🧩 Maintenance of Legacy Hardware
- Aging Capacitors: If the drive has been sitting on a shelf without power for more than a year, the internal DC bus capacitors need to be “reformed” (slowly powered up using a variable voltage source) to prevent them from exploding upon sudden full-voltage startup.
- Retrofitting: If you are building a brand new system, it is highly recommended to use current Allen-Bradley families (such as the PowerFlex 525 or 750 series), as parts and support for the 1336 are limited.
