Description
07KT97F1: Product Overview
The ABB 07KT97F1 is a compact, high-performance base unit belonging to ABB’s Advant Controller 31 series, designed for decentralized industrial automation systems. As the “brain” of the Advant Controller 31 architecture, it integrates digital/analog I/O, communication interfaces, and real-time processing capabilities to enable precise control of industrial processes—from manufacturing lines to utility systems.
Role in Automation Systems:
Positioned as a decentralized automation controller, the 07KT97F1 acts as either a standalone unit for small-scale applications or a slave device (remote processor) in larger systems. It bridges the gap between field devices (sensors, actuators) and higher-level control systems (e.g., SCADA, MES), executing control logic, processing data, and facilitating communication across the automation ecosystem.
Core Functionality:
-
I/O Processing: Handles 24 digital inputs (for switches, sensors) and 16 digital outputs (for relays, solenoids), plus 8 analog inputs (for temperature, pressure) and 4 analog outputs (for valve positioning, motor speed).
-
Communication: Equipped with a CS31 system bus interface for system expansion and 2 serial ports (COM1/COM2) compatible with MODBUS, enabling seamless integration with third-party devices and上位 systems.
-
Real-Time Control: Features a 50 kHz counter (configurable in 7 modes) for precise timing and counting tasks, critical for applications like batch processing or motion control.
-
Data Storage: Offers 480 kB of user program space and 256 kB of data storage, supporting complex control algorithms and historical data logging.
Platform Benefits (Advant Controller 31 Series):
The 07KT97F1 leverages ABB’s legacy of reliability in industrial automation, with benefits including:
-
Decentralization: Reduces wiring complexity by placing control logic closer to field devices, improving system responsiveness.
-
Scalability: Supports expansion via CS31 bus-connected modules, adapting to growing operational needs.
-
Ease of Use: Removable screw terminals and DIN rail mounting simplify installation and maintenance.

Core Features & Customer Value
1. Flexible I/O Configuration:
The 07KT97F1’s 24 digital inputs and 16 digital outputs (plus 8 analog inputs/4 analog outputs) cater to a wide range of field devices, from simple limit switches to precision pressure transducers. For example, a manufacturing plant can use the digital inputs to monitor conveyor belt sensors and the analog outputs to adjust motor speeds—all with a single module.
2. Seamless Communication:
The CS31 system bus interface allows expansion with additional I/O or communication modules, while the MODBUS-compatible serial ports enable integration with legacy systems (e.g., Siemens S7-300 PLCs). This flexibility reduces the need for costly protocol converters, saving time and money during system upgrades.
3. Real-Time Performance:
The 50 kHz counter and fast I/O response time (<1 ms) ensure precise control of dynamic processes, such as bottling lines or robotic assembly. For customers, this translates to higher product quality and reduced waste.
4. Easy Installation & Maintenance:
Removable screw terminals and DIN rail mounting make the 07KT97F1 easy to install in control cabinets, even in space-constrained environments. The LED indicators for inputs/outputs simplify troubleshooting, reducing downtime and maintenance costs.
