Overview
The Allen-Bradley 1336-GM1 is an optional interface module designed to provide digital communication between a programmable controller and SCANport devices used with Allen-Bradley’s 1336 series AC drives. Unlike traditional enclosure-mounted communications modules, the 1336-GM1 is an open-type design that derives its power directly from the drive, simplifying installation and reducing wiring complexity. This board includes both an internal SCANport connector and a Remote I/O connector for flexible system integration.
Key Features
- Open-type design powered directly from the 1336 drive
- Dual connector interface: internal SCANport link and Remote I/O cable connector
- User-configurable DIP switches for module operation and error handling
- LED indicators for module status, SCANport device status, and communication link monitoring
- Compatible with multiple drive platforms: 1336 IMPACT, PLUS, PLUS II, and FORCE
- Electrostatic discharge (ESD) sensitive components require proper handling precautions
Technical Specifications
- Module Type: Remote I/O Communications Board / Drive Option Card
- Power Source: Derived from 1336 drive (no separate power supply required)
- Primary Connectors: Internal SCANport connector, Remote I/O cable interface
- Configuration Method: DIP switches (user-programmable)
- Indicators: LED status lights for module, SCANport link, and communication status
- Weight: 0.15 to 1.47 lbs
- Revision: Series C
Typical Applications
- Distributed I/O systems using Allen-Bradley SCANport remote I/O devices
- Motion control systems requiring programmable controller to drive communication
- Factory automation with decentralized input/output control
- Process control systems integrating 1336 series AC drives with external I/O modules
