Industrial Controller for Marine & DCS Systems | ABB 07KT51

Product Overview

The ABB 07KT51 (Product ID: 1SBP260012R1001) functions as a compact and highly efficient PLC Basic Unit within the Advant Controller 31 (AC31) series. Designed for localized machine control and distributed I/O management, this unit integrates 8 digital inputs and 6 transistor outputs into a single DIN-rail mountable housing. It executes user programs via a 34 kB Flash EPROM and maintains critical data using non-volatile RAM. We supply this unit in 100% Brand New and Original condition, meeting the rigorous standards required for industrial process automation, machine packaging lines, and certified marine applications.

Technical Specifications

The 07KT51 architecture balances power consumption with high-speed digital signal processing.

Engineering Advantages

• Optimized for High-Speed Counting: The 07KT51 incorporates two dedicated hardware counters supporting frequencies up to 7 kHz. This allows the controller to interface directly with high-speed sensors and encoders for precise positioning or flow measurement without requiring specialized high-speed modules.

• Marine-Grade Reliability: This unit carries extensive marine certifications (DNV, GL, LR). The internal circuitry withstands the vibration, humidity, and thermal fluctuations found in offshore and shipboard automation environments, ensuring stable logic execution where standard PLCs fail.

• Non-Volatile Data Integrity: The 4.4 kB of user data memory utilizes non-volatile RAM, while the 34 kB program stays secured in Flash EPROM. This dual-memory strategy prevents program loss during power interruptions and ensures the controller resumes operation with zero manual intervention.

• Extreme Scalability: Despite its small footprint, the 07KT51 manages a total digital I/O map of up to 1000 points and a massive analog capacity (258 AI / 224 AO). This scalability allows it to serve as a central hub for complex distributed control systems (DCS) using the CS31 system bus.

• Space-Efficient DIN-Rail Mounting: The unit fits standard TH35-15 and TH35-7.5 rails. Its 85 mm depth and 120 mm width make it ideal for shallow control cabinets and compact machine-mounted enclosures where space is a premium.

FAQs

• Can the 07KT51 handle analog signals directly?

  The 07KT51 is a digital-focused basic unit. While it manages digital I/O locally, it accesses high volumes of analog I/O (up to 258 AI) through remote expansion modules connected via the CS31 system bus.

• Is this a direct replacement for older AC31 Series 40 modules?

  Yes. The 07KT51 is a core component of the AC31 Series 40/50 family. It maintains electrical and logic compatibility with existing Advant Controller 31 networks, making it a reliable drop-in replacement for maintenance and upgrades.

• Does the 07KT51 require a backup battery?

  The unit utilizes Flash EPROM for program storage and non-volatile RAM for data, significantly reducing reliance on batteries for logic persistence. However, verify specific application requirements if real-time clock data must persist through long-term power-off states.

• What is the condition of the hardware?

  We sell only 100% Brand New and Original ABB 07KT51 units. Every item ships in its original factory packaging with a full 12-month warranty, ensuring the internal Flash and RAM components have zero previous cycle wear.
