OMRON NX1P21140DT1 Machine Controller, 40 Integrated I/O, 24VDC, EtherCAT, EtherNet/IP 672501

The OMRON NX1P21140DT1 stands out by combining a machine controller CPU with 40 integrated I/O points in a single compact unit, eliminating the need for a separate basic I/O rack in small automation projects. This integration reduces wiring and panel space while keeping full EtherCAT motion control capability for up to four axes.

Highlights

• 40 integrated I/O: 24 digital inputs (24VDC) and 16 transistor sink outputs
• Dual industrial Ethernet: EtherCAT for motion and EtherNet/IP for data
• 1.5 MB program and data memory, minimum cycle time 1 ms
• DIN rail mounting, IP20 protection, 0–55 °C operating range
• Expandable with NX-series I/O units via the built-in expansion bus

In daily use

Programmed with Sysmac Studio, the NX1P21140DT1 handles logic, motion, and safety functions in one environment. The integrated I/O covers most small machine needs, while the EtherCAT port connects servo drives and remote I/O with deterministic cycle times. The EtherNet/IP port links to HMIs, SCADA, or upper-level controllers. A USB 2.0 Type-B port allows direct programming and troubleshooting from a PC.
