Siemens AG 6ES5948-3UR23 Cpu Processor Module

Siemens 6ES5948-3UR23 is the CPU 948R central processing unit module for the SIMATIC S5-155H PLC family. It provides 1600 KB of RAM for the user program and data, serving as the processing brain of the S5-155H controller. The module includes a 20 mA current-loop TTY interface for OP/PG/PC connections and offers two expansion points: a memory submodule (Flash EPROM) slot for nonvolatile program storage and a PG interface module slot to connect programming devices. Designed specifically for the S5-155H, the 6ES5948-3UR23 is the CPU 948R variant that combines processing power with expandable memory options within a single CPU module, enabling more capable control logic and easier program management in industrial automation environments. This CPU module is typically deployed as the core processing node in Siemens S5-155H installations, interfacing with backplane modules and peripheral interfaces to execute the user program and manage data flow across the control system.
