Engineering Advantages
-
Optimized Logic Processing: The 80186 processor executes 1K instructions in as little as 0.3 ms. This rapid processing power enables precise control over high-speed industrial machinery, reducing cycle times and improving throughput.
-
Dual Networking Versatility: This CPU integrates one Modbus Plus port and one Modbus RS232 port directly on the front panel. This dual-interface design allows for simultaneous high-level peer-to-peer networking and local HMI or programming tool connectivity without additional hardware.
-
Extensive Remote I/O Reach: The 140CPU11303 manages up to 31 remote drops and 63 distributed drops. This expansive network capability allows engineers to consolidate control for massive plant-wide systems into a single Quantum rack.
-
Reliable Memory Retention: A high-capacity 1.2 AH Lithium battery maintains the internal RAM for up to 10 years. This ensures your critical application logic and registers remain intact during extended power outages or seasonal facility shutdowns.
-
Software Continuity: Full compatibility with Concept and ProWORX 32 allows for the direct download of existing project files. This minimizes engineering labor and commissioning risks when replacing older Quantum hardware.
FAQs
-
Does the 140CPU11303 require a separate mathematical coprocessor? No. This specific model operates without a mathematical coprocessor. It handles standard arithmetic and logic operations efficiently using the core 80186 instruction set.
-
How do I replace the battery without losing my program? The CPU supports battery replacement while the power to the rack remains ON. Always verify the "Bat" status LED before and after replacement to ensure the new cell is seated correctly and providing the required voltage.
-
Is this a direct replacement for older 140CPU113 series modules? The 140CPU11303 fits standard Quantum backplanes. However, always check your existing software version (Concept or ProWORX) to ensure it supports the specific "-03" hardware revision for correct I/O mapping.
-
What is the condition of this unit? We guarantee this 140CPU11303 is 100% Brand New original Schneider Electric stock. It arrives in the original factory-sealed box, including the primary lithium battery and technical inserts.
