1336-L4 Allen Bradley

Description

Product Name: 1336-L4 Allen Braley Controller module

Product details:

The Allen-Bradley 1336-L4 is a specialized logic interface board used within the classic 1336 series of Adjustable Frequency AC Drives (specifically the 1336 PLUS, PLUS II, and IMPACT families). It is designed to bridge the communication between external control signals and the drive’s internal processing.

1. Product Overview

The 1336-L4 is a Contact Closure Interface Board. Its primary function is to allow the drive to be controlled by dry contacts or 24V DC/AC signals. It provides a localized point for wiring start/stop commands, forward/reverse toggles, and fault resets.

2. Technical Specifications

While specific specs can vary based on the main drive’s horsepower rating, the L4 board generally follows these parameters:

3. Key Advantages

• Simplified Integration: Allows the drive to interface directly with PLC outputs or physical pushbuttons without needing complex communication protocols.
• Reliability: Built with industrial-grade components designed to withstand the electrical noise and heat found in motor control centers.
• Versatility: Supports multiple control schemes, including 2-wire and 3-wire control (Momentary vs. Maintained switches).
• Plug-and-Play: Designed specifically for the 1336 architecture, ensuring seamless firmware compatibility.

4. Safety & Precautions

Warning: Working with Variable Frequency Drives involves high voltage. Always ensure the drive is powered down and the DC bus capacitors have discharged before installation.

• ESD Protection: The board is sensitive to Electrostatic Discharge. Always wear a grounding wrist strap during handling.
• Jumper Settings: Before powering up, verify that the jumpers (S1, etc.) are correctly set for your logic type (Sink/Source).
• Terminal Torque: Ensure all wiring terminals are tightened to the manufacturer’s specified torque to prevent arcing or signal loss.
• Compatibility: Verify that your drive’s firmware version supports the L4 board, as some very early 1336 models may require updates.

5. Typical Applications

The 1336-L4 is used in legacy industrial systems where robust, hard-wired control is preferred over networked communication (like EtherNet/IP).

• Conveyor Systems: For simple Start/Stop and E-Stop integration.
• Pumping Stations: Interfacing with float switches or pressure sensors.
• HVAC Fans: Connecting to building automation system (BAS) relays.
• Material Handling: Managing directional control and speed selection via physical selector switches.
