Product Overview
The Omron NX1P2-1140DT is the NX1P2-series compact machine automation controller with 40 built-in I/O and NPN transistor outputs It is 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 memory, 2 MB variables, and an EtherCAT master plus EtherNet/IP scanner on a 2 ms primary task cycle. Built-in I/O is 24 DC inputs (PNP or NPN selectable) plus 16 NPN (sinking) transistor outputs at 0.5 A per point. Up to 8 NX expansion units and 16 EtherCAT remote I/O nodes. Key specs: Built-in I/O 40 points: 24 DC inputs (PNP or NPN) + 16 NPN transistor outputs; Output Rating 0.5 A per point, 1.5 A per common at 24 VDC; no load short-circuit protection on NPN; Program / Variables 1.5 MB program memory; 2 MB variables; SD memory card slot; Motion / Cycle Primary task cycle 2 ms; 4 EtherCAT synchronous servo axes + 4 PTP axes (8 total); Communication Ports 2 Ethernet (EtherCAT master + EtherNet/IP scanner); 0 USB; 2 serial option board.

Best-Fit Applications
- Eight-axis packaging line where the NX1P2-1140DT runs 4 servo axes via EtherCAT and 4 stepper axes via PTP pulse to a single NPN field bank
- Compact conveyor cell with 24 VDC NPN sensors on the built-in inputs and an NB7W-TW01B HMI on EtherNet/IP for operator control
- Spare replacement on a small NPN machine where Sysmac Studio has the project backup on the SD memory card and no firmware rewrite is needed
Buying Checklist
- Choose the NX1P2-1140DT1 instead when the field devices are PNP sourcing rather than NPN sinking on the same 40-I/O body.
- Choose the NX1P2-1040DT instead when only 2 servo axes are needed on the same NPN 40-I/O body, to save cost.
- Choose the NX102-1200 instead when the cabinet needs more than 8 motion axes or separate CPU and I/O rack mounting.

FAQ for NX1P2-1140DT
What is the Omron NX1P2-1140DT 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 eight-axis packaging lines with 4 servo + 4 PTP axes, compact conveyor cells with 24 VDC NPN sensors on EtherNet/IP, and spare replacement where the Sysmac Studio backup is on the SD card.
NX1P2-1140DT vs NX1P2-1140DT1 - what is the difference?
Both are NX1P2 compact controllers with 40 built-in I/O. The 1140DT has NPN (sinking) outputs that switch the low side of a load. The 1140DT1 has PNP (sourcing) outputs that switch the high side and add load short-circuit protection. Choose the 1140DT for NPN field devices; choose the 1140DT1 for PNP field devices or short-circuit protection.
How many motion axes does the NX1P2-1140DT control?
Up to 4 EtherCAT synchronous servo axes and 4 PTP axes for an 8-axis total. The 4 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 an NX-PG0112 slice. For more axes step up to NX102-1200.
Does the NX1P2-1140DT 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.
