Product Overview
The Omron NX1P2-1040DT is the NX1P2-series compact machine automation controller with 40 built-in digital I/O and NPN outputs, manufactured by Omron Corporation. Hengyixin Automation stocks this controller in Xiamen and ships within 3-5 business days to most Asian, European, and North American ports.
It runs on 24 VDC and combines a 1.5 MB program / 2 MB variables controller with EtherCAT master (2 synchronous servo axes max, 4 PTP axes max) and EtherNet/IP scanner (32 connections). Primary task cycle 2 ms. Built-in I/O: 24 DC inputs (PNP/NPN selectable) and 16 NPN (sinking) outputs at 0.5 A per point.
Two Ethernet ports (EtherCAT + EtherNet/IP), no USB, and two serial option board slots for NX1W-CIF01 (RS-232C), NX1W-CIF11 (RS-422/485), or NX1W-CIF12 (isolated RS-485). Up to 8 NX expansion units stack on the right; up to 16 remote I/O nodes over EtherCAT. The PNP sibling at the same 40 I/O body is NX1P2-1040DT1. The smaller 24-I/O variant is NX1P2-9024DT. For more axes step up to NX102-1200.

- SKU: NX1P2-1040DT
- Series: NX1P2-series compact machine automation controller (NX1 CPU family)
- I/O: 40 points
Best-Fit Applications
- Four-axis packing machine where the NX1P2-1040DT runs 2 servo axes via EtherCAT and 2 PTP axes via pulse output
- Compact conveyor cell with 24 VDC sensors on the built-in DC inputs and an NB5Q-TW01B-V1 HMI on EtherNet/IP
- Spare replacement on a small machine where the original NX1P2-1040DT was lost and Sysmac Studio has the project backup
Buying Checklist
- Pick the NX1P2-1040DT when the panel needs 40 built-in I/O (24 in / 16 NPN out) on a single compact PLC with EtherCAT + EtherNet/IP.
- Pick the NX1P2-1040DT1 instead when the loads need 16 PNP (sourcing) outputs instead of 16 NPN (sinking) outputs on the same 40-I/O body.
- Pick the NX1P2-9024DT instead when the panel only needs 24 built-in I/O (14 in / 10 out) on a smaller, less expensive body.

FAQ for NX1P2-1040DT
What is the Omron NX1P2-1040DT used for?
It is the NX1P2-series compact machine automation controller with 40 built-in I/O (24 DC inputs + 16 NPN outputs). Typical uses are four-axis packing machines with 2 servo + 2 PTP axes, compact conveyor cells with 24 VDC sensors and an NB5Q HMI on EtherNet/IP, and spare replacement on a small machine where the Sysmac Studio backup is ready.
NX1P2-1040DT vs NX1P2-1040DT1 - what is the difference?
Both are NX1P2 compact controllers with 40 built-in I/O (24 in + 16 out). The 1040DT has NPN (sinking) transistor outputs that switch the low side of a load; the 1040DT1 has PNP (sourcing) outputs that switch the high side and add load short-circuit protection. Pick the 1040DT for NPN field devices; pick the 1040DT1 for PNP field devices or where load short-circuit protection is required.
How many motion axes does the NX1P2-1040DT control?
Up to 2 EtherCAT synchronous servo axes and 4 PTP axes (6 total). The 2 EtherCAT axes connect R88D-1SN02H-ECT or R88D-KN02H-ECT-Z servo drives and use Sysmac Studio motion control functions. The 4 PTP axes use pulse outputs from the built-in I/O or from an NX-PG0112 pulse output slice. For more axes (up to 8 servo) step up to NX102-1200.
Does the NX1P2-1040DT have USB and serial ports?
No USB. Two serial option board slots accept NX1W-CIF01 (RS-232C, 15 m max), NX1W-CIF11 (RS-422 / RS-485, 50 m max), or NX1W-CIF12 (isolated RS-422 / RS-485, 500 m max). Programming is over Ethernet from Sysmac Studio; the SD memory card slot holds the project backup.
