1336-R1-SP2A Allen Bradley

Description

Product Name: 1336-R1-SP2A  Allen Braley Programmable controller

Product details:  

The 1336-R1-SP2A serves as a critical internal component that manages the initial energization of the drive’s DC bus. Its primary role is to limit the “inrush current” when power is first applied, protecting the bridge rectifier and DC capacitors from thermal stress and potential failure.

2. Technical Specifications

3. Key Advantages

• Enhanced Component Longevity: By controlling the precharge cycle, it prevents the DC bus capacitors from charging too rapidly, which extends their operational lifespan.

• System Stability: Reduces the risk of tripping upstream circuit breakers or blowing fuses during the drive’s power-up sequence.

• Original Equipment Manufacturer (OEM) Reliability: As a genuine Allen-Bradley part, it ensures exact timing and resistance values required for the 1336 drive’s logic control.

• Direct Replacement: Designed for “plug-and-play” installation within compatible frame sizes, minimizing downtime during repairs.

4. Product Application

The 1336-R1-SP2A is used exclusively within the following Allen-Bradley AC Drive families:

• 1336 PLUS (SDR/E): General-purpose industrial motor control.

• 1336 FORCE: High-performance vector control for demanding torque applications.

• 1336 IMPACT: High-speed precision applications using Force Control technology.

Common Industries:

• Steel and Aluminum Mills (Heavy-duty cycling)

• Water/Wastewater (Pumping stations)

• Oil and Gas (Centrifuges and compressors)

• Material Handling (Conveyor systems)

5. Important Considerations & Precautions

• Capacitor Discharge: Before attempting to replace this board, ensure the drive has been disconnected from the power source for at least 5–10 minutes. Use a voltmeter to verify that the DC bus voltage has dropped to a safe level (under 50VDC).

• Static Sensitivity: This board contains ESD (Electrostatic Discharge) sensitive components. Use a grounding wrist strap during handling.

• Matching Series/Revision: Ensure your drive’s frame size matches the SP2A requirement. Using the wrong precharge board can lead to resistor burnout or “Precharge Fault” codes on the drive HMI.

• Environmental Check: When replacing the board, check the surrounding area for signs of overheating or “leaking” capacitors, as a failing precharge board is often a symptom of larger DC bus issues.
