Allen-Bradley 1794-L34 FlexLogix I/O Module System

Allen-Bradley 1794-L34 FlexLogix Controller System is the CPU at the heart of the FLEX I/O modular I/O family, coordinating data exchange with FLEX I/O modules on the local FLEX bus. It provides 512 KB of fixed memory for program and data storage, larger than the 64 KB found in the 1794-L33 model. The L34 is designed for DIN-rail installations and supports local or distributed FLEX I/O configurations, with module placement defined for a FLEX I/O network. It supports a range of FLEX I/O modules (digital, analog, HART analog, and specialty I/O) that typically offer 4–32 points per module, all connected via the FLEX I/O bus to enable scalable automation control.
