Allen-Bradley 1794-L34 FlexLogix Controller Processor

Description

The Allen-Bradley 1794-L34 FlexLogix Controller Processor is a programmable logic controller (PLC) designed for small to medium-scale automation control systems. It features a 5434 processor with high-speed data processing and execution capabilities, supporting diverse industrial control tasks. Key electrical specifications include a nominal 24V DC power supply with an operating range of 19.2 to 31.2V DC; power consumption is 25.5W at 19.2V DC and 20.4W at 24V DC, with a weight of approximately 0.75 kg.

Equipped with a single RS-232 serial port for direct external device communication, the controller also supports installation of up to 2 communication adapters such as 1788 sub-cards, enabling connection to Ethernet I/P, DeviceNet, and ControlNet networks. It offers selectable user memory of 64K or 512K bytes, and leverages the Logix control engine to deliver sequential, motion, process, and drive control functionality.

The 1794-L34 shares consistent programming and I/O configuration with other Logix processors, and includes a multi-task operating system that supports 8 configurable tasks with adjustable priorities, plus 1 continuous task. Each task can run up to 32 independent programs with local data and ladder logic, and it supports symbolic addressing compliant with IEC1131-3, user-defined data structures, and reusable standard subroutines for flexible, scalable automation solutions.
