This hardware unit houses an Intel 80486 microprocessor equipped with an integrated mathematical coprocessor to calculate floating-point variables and manage execution cycles. By serving as the central logical coordinator on the local backplane, this module reads discrete and analog data registers, runs cyclic industrial programs, and commands remote and distributed sub-networks via onboard serial paths.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e140CPU43412A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eSchneider Electric\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eGermany\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.85 kg (1.87 lbs)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003eStandard single-slot Modicon Quantum module dimensions\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e0 to 60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e4.5 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProcessor Type\u003c\/td\u003e\n\u003ctd\u003eIntel 80486 with Mathematical Coprocessor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eClock Frequency\u003c\/td\u003e\n\u003ctd\u003e66 MHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInternal RAM\u003c\/td\u003e\n\u003ctd\u003e896 kB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInstruction Time\u003c\/td\u003e\n\u003ctd\u003e0.1 to 0.5 ms per 1K instructions\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWatchdog Timer\u003c\/td\u003e\n\u003ctd\u003e250 ms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBus Current Requirement\u003c\/td\u003e\n\u003ctd\u003e1250 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOnboard Communication Ports\u003c\/td\u003e\n\u003ctd\u003e1 x Modbus Plus, 2 x Modbus RS232\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLocal\/Remote I\/O Capacity\u003c\/td\u003e\n\u003ctd\u003e64 I \/ 64 O local, 64 I \/ 64 O remote\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDistributed I\/O Capacity\u003c\/td\u003e\n\u003ctd\u003e500 I \/ 500 O distributed across maximum 31 drops\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery Configuration\u003c\/td\u003e\n\u003ctd\u003eLithium, 1.2 Ah, 10-year service life\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage Temperature\u003c\/td\u003e\n\u003ctd\u003e-40 to 85 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRelative Humidity\u003c\/td\u003e\n\u003ctd\u003e95 percent relative humidity non-condensing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Operational Altitude\u003c\/td\u003e\n\u003ctd\u003e5000 m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCertifications\u003c\/td\u003e\n\u003ctd\u003eCE, UL 508, CSA C22.2 No 142, FM Class 1 Div 2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eProfinet and EtherNet\/IP Deterministic Network Expansion\u003c\/h3\u003e\n\u003cp\u003eThis processor block interfaces directly with Modicon expansion modules to manage data flow across Profinet and EtherNet\/IP deterministic networks. The internal backplane driver architecture maintains strict timing parity during multi-rack data mapping operations, supporting the simultaneous insertion of up to six separate communication modules (including NOM, NOE, and CR components). Local register allocation logic updates up to 500 distributed input and output words per node without dropping communication cycles. Firmware flash compatibility protocols verify packet verification hashes during runtime, preventing data corruption across the serial Modbus Plus and RS232 channels when the module handles high-density network segmentation.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What operational risks occur if the backplane current draw exceeds the module 1250 mA rating?\u003c\/p\u003e\n\u003cp\u003eA: The 1250 mA rating defines the maximum current consumption of the CPU from the rack backplane power supply module. Exceeding the combined current thresholds of the installed rack components can cause backplane voltage drops, which trips the 250 ms internal watchdog timer and forces a system reset.\u003c\/p\u003e\n\u003cp\u003eQ: How should a firmware compatibility conflict be addressed when replacing a legacy 140CPU43412A?\u003c\/p\u003e\n\u003cp\u003eA: Replacement modules must run a firmware revision that matches the configuration file compiled in the legacy programming software. If an unresolvable firmware or hardware generation gap occurs, hardware migration to a Modicon M580 platform using a BMEP582040 processor is recommended.\u003c\/p\u003e\n\u003cp\u003eQ: Can the internal lithium battery be hot-swapped while the CPU module is offline?\u003c\/p\u003e\n\u003cp\u003eA: No. The 1.2 Ah lithium battery must only be replaced while the Quantum backplane power supply is fully energized. Removing the battery while the rack is powered down interrupts the bias voltage to the 896 kB internal RAM, erasing the user program and register configuration values.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBackplane Insertion:\u003c\/strong\u003e Confirm the local backplane power supply is switched off before inserting the module into slot 1 or slot 2 of the Quantum chassis to prevent pins from shorting.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModbus Line Shielding:\u003c\/strong\u003e Ground all Modbus Plus and RS232 serial communication cable shields at the point of entry into the enclosure using dedicated grounding bars to redirect 8 kV air ESD and high-frequency EMI.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery Verification:\u003c\/strong\u003e Verify the 1.2 Ah lithium battery is properly seated in the front panel compartment and check that the battery fault LED status remains unlit during initial initialization sequences.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConvective Thermal Clearances:\u003c\/strong\u003e Ensure at least 80 mm of vertical air space exists above and below the Quantum rack assembly to maintain temperatures below the 60 deg C operating threshold inside sealed industrial panels.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Schneider","offers":[{"title":"Default Title","offer_id":43449704153178,"sku":"140CPU43412A","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/182_47419522-a30d-4daf-a26f-725fc85751c7.jpg?v=1780539669","url":"https:\/\/www.spareoil.com\/products\/140cpu43412a-schneider-electric-cpu-module-new-original-stock","provider":"SpareOil Automation","version":"1.0","type":"link"}
