Overview
The Allen-Bradley 1336-MOD-L3 (alternate marking 1336-M0D-L3) is a specialized logic interface board designed for integration with Allen-Bradley 1336 PLUS series adjustable frequency AC drives. This module provides interface options alongside the 1336-MOD-L1 and L2 variants, enabling flexible control strategies for industrial motor applications. The 1336-MOD-L3 has a NEMA Type 4 enclosure for protection and 115 Volts DC operating voltage, providing a self-contained NEMA Type 1 enclosed assembly that connects to an Allen-Bradley 1336 AC drive.
Key Features
- Interface logic board rated 115VAC with PC board and control board assembly suitable for mounting
- Direct input compatibility with standard maintained contact or pushbutton circuits
- User-supplied maintained contact or stop pushbutton connections via the optional L1, L2, or L3 Logic Interface Board
- Modular connector design for simplified field replacement and troubleshooting
- Board has been discontinued by manufacturer but surplus units remain available for legacy system support
Technical Specifications
The 1336-MOD-L3 operates as a discrete logic control interface for the 1336 drive family:
- Operating Voltage: 115V AC/DC
- Enclosure Type (Logic Board): NEMA Type 1 (IP20)
- Drive Compatibility: Allen-Bradley 1336 PLUS series
- Connection: Terminal block interface (TB3 user input connections)
- Input Configuration: Programmable control inputs
- Alternative Part Numbers: 120673, SP-120675, SP-120673, 148294, PN-C22206
- Condition: Used/Refurbished (surplus inventory)
Typical Applications
The 1336-MOD-L3 is commonly deployed in legacy industrial automation systems where discrete-level control is preferred over communication-based interfaces:
- Start/stop control via external pushbuttons or relay contacts
- Forward/reverse motor direction control
- Jog speed pre-programming and activation
- Retrofit of older conveyor and pump drive systems
- Integration in NEMA enclosures with hardwired control logic
- Systems requiring simple contact-based interface without serial communication
Compatibility & Replacements
The 1336-MOD-L3 is purpose-built for the 1336 PLUS drive platform and is not interchangeable with modern variable frequency drive logic boards. This board works in tandem with 1336-MOD-L1 and L2 interface options per the 1336-MOD-L1, L2, or L3 instruction manual and Appendix A of the drive documentation. Known equivalent part numbers include 120673, PN-C22206, and 148294. For modern drive replacement, consider current-generation Allen-Bradley PowerFlex 700 or 750 series drives with integrated logic control. Obsolescence support and repair services are available through specialty distributors such as Radwell, DO Supply, and Santa Clara Systems.
