Products Description
ABB 07KT97 WT97 Central Processing Unit
The ABB 07KT97 WT97 is a central processing unit designed as the core control element within ABB automation and PLC-based systems. It is responsible for executing control programs, processing real-time data, and coordinating communication between I/O modules and peripheral devices. Unlike interface or expansion modules, the 07KT97 WT97 directly determines system response time, logic accuracy, and overall operational stability.
Built for long-term industrial use, this CPU delivers deterministic performance and reliable processing capability for applications where consistent control execution is essential.
With over 50 million in inventory, PLC EXPORT delivers only brand-new, authentic components- ready to ship,
rigorously tested, and backed by professional technical support.

Functional Role / System Position
The 07KT97 WT97 serves as the primary control and logic execution unit:
Field Signals → I/O Modules → 07KT97 WT97 CPU → Output Modules / Actuators
It collects input data from connected I/O modules, executes the control logic stored in its program memory, and issues commands to output modules. Its position at the center of the control architecture makes it critical for synchronized system behavior and fault handling.
Key Features / Functional Capabilities
■ Executes control logic with deterministic cycle times
■ Manages communication with local and remote I/O modules
■ Supports real-time data processing for industrial automation tasks
■ Designed for stable 24/7 continuous operation
■ Integrates seamlessly within ABB PLC and control architectures
■ Provides system status monitoring and diagnostic feedback
Application Areas / Typical Use Cases
▪ Machine-level control in manufacturing and assembly systems
▪ Process automation with centralized logic execution
▪ Control cabinets requiring compact and reliable CPU solutions
▪ Modernization of legacy ABB control platforms
▪ Industrial systems demanding predictable and repeatable control cycles
