Excellent PLC
Product Introduction
The Allen-Bradley 1794-L34 FlexLogix Processor is a powerful and flexible controller designed for distributed automation systems that require higher memory capacity and expanded communication capabilities. As part of the FlexLogix platform from Rockwell Automation, this processor combines the performance of Logix architecture with the modular flexibility of FLEX I/O systems.
With 512 KB of user memory, the 1794-L34 is well-suited for medium-scale automation applications involving complex control logic, analog processing, and coordinated system operations. It features one RS-232 serial port for communication and supports two slots for 1788 communication cards, enabling integration with various industrial networks such as Ethernet/IP, ControlNet, and DeviceNet.
Designed for 24 VDC operation, the processor offers reliable performance in industrial environments while maintaining a compact footprint for control panel installations.
