1794-L34 Allen-Bradley FlexLogix Embedded Controller for Distributed Industrial Automation
The 1794-L34 integrates the Logix processing engine onto the FLEX I/O platform. It eliminates long-distance field-wiring costs by decentralizing control directly to the machine site. Featuring dual network slots, it is designed for distributed industrial automation and modular factory networks.
- 512 KB Memory: Stores user program and data locally
- Dual 1788 Slots: Accepts network daughtercards for EtherNet/IP, ControlNet, or DeviceNet
- RS-232 Port: Provides DF1 or ASCII communication
- Engineer's Note: Series B hardware adds non-volatile memory support to prevent program loss during power failure
- Project Case: Deployed in factory automation to control localized FLEX I/O modules and communicate via 1788 network cards
