Program capacity is 1.5 MB, with 32 kB non-volatile memory and 2 MB flash for data logging or recipe storage — no battery backup needed for the program retention. ## I/O count and expandability for machine control The base unit gives you 40 I/O points (24 in, 16 out), and the NX1P supports expansion via the NX bus — you can add analog, temperature, or additional digital slices up to the CPU's addressing limit. Transistor outputs are rated 4 A total load current, suitable for driving solenoid valves, contactor coils, or indicator banks directly within that budget. The real-time clock is built in, so time-stamped alarms and batch logs are available without an add-on module. ## Programming and fieldbus integration It supports Ladder Diagram and Structured Text (IEC 61131-3), so you can reuse existing logic or write structured code for complex sequences. The EtherCAT port runs at 100 Mbps, giving deterministic cycle times for motion axes and fast I/O update rates — typical for packaging, assembly, or material-handling lines.","metaTitle":"Omron NX1P21140DT1 PLC, 24DI 16DO, EtherCAT/EtherNet/IP","metaDescription":"Omron NX1P21140DT1 PLC, 24 digital inputs, 16 transistor outputs, 28.8 VDC, EtherCAT and EtherNet/IP, 1.5 MB program capacity.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["PLCs (Programmable Logic Controllers)"],"specifications":{"title":"NX1P21140DT1","Series":"NX","Data Buffer":"32kB Non-Volatile Memory, 2MB Flash Memory","description":"Programmable Logic Controller 24DI 16DO 28.8VDC EtherCAT / EtherNet / IP 1.5 MB","Load Current":"4 A","Expandability":"Yes","Mounting Type":"DIN Rail Mount","Battery Backup":"No","Baud Rate Max.":"100 Mbps","Digital Inputs":"24","Real-Time Clock":"Yes","lifecycle_stage":"current","Program Capacity":"1.5 MB","Termination Type":"Spring Clamp Terminal","Input/Output Max.":"40 I/O Points","Digital Output Type":"Transistor","Operating Voltage Max.":"28.8 VDC","Operating Voltage Min.":"20.4 VDC","Programming Language Used":"Ladder Diagram (LD);Structured Text (ST)","Communication Interface Type":"EtherCAT;EtherNet / IP","Number of Transistor Outputs":"16"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1,172.00 – $3,159.06","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/2e01f183b879f1e1b433c47ec79f4f1a.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/omron/NX1P21140DT1","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/omron/NX1P21140DT1 when reusing this data.
