1336-L7E Control Interface Board

January 15,2025

Introduction to the 1336-L7E Control Interface Board
The 1336-L7E control interface board is a robust solution designed for high-performance applications in industrial environments. Known for its precision in controlling and providing feedback, this interface board is widely used in combination with adjustable frequency AC drives, particularly from the 1336 IMPACT series. It provides seamless integration with programmable logic controllers (PLCs) and offers versatility in its configuration.

Key Features of the 1336-L7E Control Interface Board
The 1336-L7E board features TTL contact closure with encoder feedback inputs, making it a powerful tool for systems requiring precise feedback. It is compatible with specific PLCs, including the 1771-OYL and 1171-OZL models, enabling smooth communication between the drive and controller. The interface board’s encoder mode can be activated by properly connecting an L option board to the J7 and J9 connectors on the lower part of the control board. This feature ensures that users can easily configure their systems for maximum efficiency.

Installation and Setup of the 1336-L7E Interface Board
Before beginning installation or maintenance procedures, it is crucial to ensure that the DC bus voltage has fully discharged. This can be verified by measuring the voltage across the positive and negative terminals of the TB1 terminal block. Once confirmed, you can proceed with connecting the interface board. The 1336-L7E board allows users to tailor their control wiring configurations to meet the needs of specific drive applications, enhancing overall system flexibility.

Control Wiring Configurations and Logic Requirements
The interface board supports multiple control wiring configurations, providing flexibility for various industrial setups. The circuits interacting with the board need to support low=true logic, which can sink around 10 milliamps and bring the low terminal voltage to 3 Volts DC or lower. For optimal performance, using reed-type input devices is highly recommended in such configurations. Once the TB3 terminal is true, the contact input of the interface will close, triggering the desired control action.

ESD Safety and Maintenance Considerations
As with any sensitive electronic component, the 1336-L7E interface board includes elements that are susceptible to electrostatic discharge (ESD). Therefore, proper ESD control procedures must be during installation to prevent damage. Additionally, during troubleshooting or repairs, it’s essential to ensure that all power supplies are fully disconnected to avoid electric shock risks. This attention to safety ensures that both the board and the user remain protected.

Conclusion: Enhancing Performance and Safety with the 1336-L7E

The 1336-L7E control interface board is an essential component for achieving precise control and feedback in industrial drive systems. Its compatibility with the 1336 IMPACT series, along with its flexible wiring configurations and ESD precautions, ensures that users can optimize their systems for both performance and safety. Whether you're setting up a new system or performing maintenance on an existing one, the 1336-L7E provides the reliability and precision needed to meet the demands of modern industrial operations.
