It runs at 66 MHz and carries 548 kB of internal RAM. Two integrated Modbus Plus ports and two Modbus ports provide connectivity. The processor supports up to 2 local racks with a mix of slots. This processor is marked obsolete by the manufacturer. There is no official successor listed. ## I/O Architecture & Memory Discrete I/O capacity reaches 31,744 inputs and 31,744 outputs local, with additional remote and distributed capacity via Modbus Plus and S908 remote I/O. Analogue I/O is unlimited within 27 local slots, supporting up to 500 inputs and 500 outputs per Modbus Plus network. Memory includes 548 kB RAM for logic and data. ## Environmental & Certifications The unit is conformal coated (Humiseal 1A33) for protective treatment. Standards include HazLoc, indicating suitability for hazardous locations.","metaTitle":"140CPU31110C Unity Processor, 66 MHz, Modbus Plus, HazLoc -","metaDescription":"Schneider Modicon 140CPU31110C Unity processor, 66 MHz, 548 kB RAM, HazLoc.
