Description

ABB 07CT41 1SBP260022R1001 AC31 Central Processor Unit

The 07CT41 1SBP260022R1001 is a compact, stand-alone central processing unit for the ABB AC31 system, integrating local digital I/O with flexible communication interfaces.¹

Technical Operational Overview

The 07CT41 (Order Number: 1SBP260022R1001) functions as the primary logic controller for distributed or independent automation tasks within the Advant Controller 31 range. This central unit provides an efficient balance of local signal processing and networking capabilities. By featuring 8 onboard digital inputs and 6 transistorized outputs, the module allows for direct hardware interfacing without immediate need for expansion modules.

System designers benefit from the module’s robust communication architecture. Specifically, the 07CT41 supports RS232 protocols for dedicated programming tasks while simultaneously offering MODBUS® or ASCII compatibility for broader system integration.³ Furthermore, the 24 V DC inputs utilize galvanic isolation to shield the processor from field-side electrical interference. This ensures high operational uptime in electrically noisy industrial environments.

Key Technical Characteristics

• Integrated I/O Configuration: Equipped with 8 isolated 24 V DC digital inputs and 6 high-speed 24 V DC transistor outputs.⁴
• Switching Performance: Supports a nominal load of 0.5 A per output channel, providing reliable control for solenoids, relays, and indicators.
• Dual Communication Ports: Enables seamless connectivity for both local logic updates and remote data acquisition via MODBUS®.
• Expandable Architecture: Operates as a stand-alone controller while remaining extensible to accommodate larger I/O counts via system bus expansion.⁵
• Compact Footprint: Optimized for space-critical control cabinets, weighing only 0.34 kg with a streamlined mechanical profile.
• Advanced Diagnostics: Features front-mounted status indicators to facilitate rapid fault identification and signal verification.
