Siemens TI435DC1-CPU Programmable Logic Controller Module

Siemens TI435DC1-CPU is the central processing unit module for the Simatic TI-435 family within the 405-series PLCs. Designed as the controller’s brain, this CPU module executes the user program, handles data processing, and coordinates communication with I/O and peripheral modules via the TI-405 backplane. As part of the TI435DC1-CPU configuration, it supports standard plug‑in installation in compatible TI-405 racks and works with a range of TI-405 I/O modules to form a tailored control system. Typical applications include automated machinery, process control loops, and factory automation where legacy TI-405 hardware is still deployed; this CPU module enables sequencing, timer and counter functions, and integration with existing Siemens industry components in the TI-435/405 ecosystem.
