Supplied from remaining channel stock; full specifications, lifecycle and same-series options are below.","salesMarkdown":"## Overview This processor carries Checks for Process control Hot standby, operates as an Ethernet router, and is certified for HazLoc environments plus California Proposition 65 compliance. It ships in a PCE package with 18-month warranty. Application structure supports one cyclic/periodic master task plus one periodic fast task (forbidden in Hot Standby), 128 I/O interrupt tasks, 128 interrupt tasks, 32 timer interrupt tasks, and 4 auxiliary tasks — all forbidden in Hot Standby mode. System overhead runs 0.2 ms for the fast task and 1 ms for the master task. The key switch controls memory port on/off. ## Communication & I/O architecture Integrated connections include one Modbus Plus port (SUB-D 9 female), one Modbus port, one USB port, and one MT-RJ multimode fiber optic link for interconnecting primary and secondary PLCs up to 4 km apart. The module also functions as an Ethernet router. The module occupies slot 0 in a 2-rack local configuration with 10 slots per rack. Six optional modules (Ethernet, Modbus, Modbus Plus, Profibus DP, Sy/Max) can be added. Application-specific I/O includes high-speed interrupt inputs, serial link, accurate time stamping, and counter functions. ## Applications The 140CPU67160 sits at the heart of Modicon Quantum Hot Standby systems — redundant controller pairs in process plants, water treatment facilities, power generation, and critical infrastructure where a single PLC failure cannot stop production. The fiber optic link between primary and secondary processors maintains synchronisation and bumpless transfer on fault. Outside Hot Standby, it serves as a standalone Unity processor for medium-to-large machine and process automation — packaging lines, conveyor networks, chemical batch skids — coordinating distributed I/O over Modbus Plus and Ethernet, with the Ethernet router function handling plant-wide data routing. ## Compliance & certifications Product certifications include CE, UL, Misc (Marine), CSA, and GOST. The module carries HazLoc approval for hazardous location installations and is listed under California Proposition 65. These certifications cover the unit as shipped; no separate RoHS or REACH declarations are listed in the evidence.","metaTitle":"Schneider 140CPU67160 Modicon Quantum Unity Hot Standby Processor","metaDescription":"Schneider Modicon Quantum 140CPU67160 Unity processor: 266 MHz, 1024 kB RAM, Hot Standby, Ethernet, Modbus Plus, fiber optic, HazLoc, CE, UL, CSA, GOST.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":[],"specifications":{"Checks":"Process control Hot standby","Category":"18150 - QUANTUM CONTROLLERS,HSBY,COMM.","Standards":"HazLoc","Clock frequency":"266 MHz","Number of racks":"2 - local","Number of slots":"2 10 16 4 6","Switch Function":"Key switch memory port on/off","System overhead":"0.2 ms fast task 1 ms master task","lifecycle_stage":"eol_hot","Local signalling":"1 LED (green) for Ethernet activity (COM) 1 LED (red) for Ethernet collision","Range of Product":"Modicon Quantum automation platform","Memory description":"Expandable 7168 kB - program with PCMCIA card Expandable 8 MB - file storage with PCMCIA card Internal RAM 1024 kB - 512 kB for data","Analogue I/O number":"500 inputs, 500 outputs - distributed - per network Modbus Plus Unlimited (31 drops of 28 slots max) - ethernet remote I/O 1984 inputs,1984 outputs - remote 0 - local - forbidden in Hot Standby application","Discrete I/O number":"31744 inputs, 31744 outputs - remote 8000 inputs, 8000 outputs - distributed - per network Modbus Plus Unlimited (31 drops of 28 slots max) - ethernet remote I/O 0 - local - forbidden in Hot Standby application","Mode of Transmission":"Multi mode","Application structure":"1 periodic fast task - forbidden in Hot Standby application 128 I/O interrupt tasks - forbidden in Hot Standby application 128 interrupt tasks - forbidden in Hot Standby application 32 timer interrupt tasks - forbidden in Hot Standby application 4 auxiliary tasks - forbidden in Hot Standby application 1 cyclic/periodic master task -","Communication Service":"Ethernet router","Electrical connection":"1 female connector SUB-D 9 for connecting to the Modbus Plus network 1 connector RJ45 for connecting Modbus bus 1 connector MT-RJ (multimode fiber optic) for interconnecting primary and secondary PLCs up to 4 km","Nbr. of units in pkg.":"1","Bus current requirement":"2500 mA","Application specific I/O":"High-speed interrupt inputs Serial link Accurate time stamping Counter","Product or Component Type":"Unity processor","Integrated connection type":"1 Modbus Plus 1 Modbus 1 USB 1 optic fibre Hot Standby","Number of optional modules":"6 Ethernet, Modbus, Modbus Plus, Profibus DP, Sy/Max)","Number of remote I/O station":"31 - 2 S908 remote I/O 31 - 2 ethernet Quantum remote I/O 16 - 2 ethernet X80 remote I/O","Maximum number of connections":"1 USB 2 AS-Interface - distributed 4 AS-Interface - remote 6 Ethernet TCP/IP - local 6 Modbus Plus - local 6 Profibus DP - local 1 Modbus RS232/485 Modbus/ASCII)","Number of instructions per ms":"10.28 Kinst/ms 100 % Boolean 10.07 Kinst/ms 65 % Boolean and 35 % numerical","Number of distributed I/O station":"63 1 3 Modbus Plus"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10,805.73 – $11,143.00","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/6891fb44880557061b2006d9bd094eb0.pdf","sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/140CPU67160/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/140CPU67160","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/140CPU67160 when reusing this data.
