Product Overview

The 07KR51 (1SBP260014R1001) is a high-performance, compact PLC basic unit within the ABB Advant Controller 31 (AC31) series. This central unit serves as the core intelligence for small to medium-scale automation tasks, providing integrated digital signal processing and logic control. Operating on 230 VAC power, the 07KR51 is equipped with a built-in CS31 system bus interface, enabling it to act as a bus master to manage remote I/O expansion modules. Its robust relay outputs and high-speed hardware counters make it an ideal choice for machinery control, HVAC systems, and distributed process monitoring.

Technical Specifications

The 07KR51 (1SBP260014R1001) is engineered to meet rigorous industrial standards, combining power supply, I/O, and CPU functions in a single module.

Functional Capabilities

Integrated Communication: The 07KR51 (1SBP260014R1001) features a dedicated CS31 fieldbus port, allowing for deterministic communication with remote analog and digital modules over long distances without decreasing CPU scan times.
Relay-Based Actuation: The six onboard relay outputs provide high-current switching capabilities, eliminating the need for interposing relays when driving solenoid valves or small motors directly.
Time-Critical Processing: With two integrated hardware counters and a real-time clock, the unit manages precise event counting and time-of-day control logic, essential for dosage and logging applications.
Industrial Hardening: Designed for high-interference environments, the module is certified for operation within a -40°C to +75°C storage range and maintains functionality in humid, non-condensing conditions.
