Product Overview
The Omron NJ101-1000 is a Sysmac NJ1 machine-automation controller CPU unit, 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.
The CPU runs a 3 MB program with 0.5 MB retained plus 2 MB non-retained variable memory on a 1 ms primary task cycle. Built-in ports cover EtherCAT master for up to 64 nodes and 2 servo axes, EtherNet/IP for up to 32 connections, and a USB programming port. An SD memory card slot sits on the front face for project and recipe backup.
Up to 40 CJ-series units mount across the CPU rack plus three expansion racks; local I/O capacity is 2560 points. Programming runs in Sysmac Studio Standard Edition under IEC 61131-3 (Ladder, Structured Text, Function Block, Sequential Function Chart). For the no-motion sibling, pick the NJ101-9000. For more program and 8 servo axes, pick the NJ301-1200.
Key Features
- Sysmac NJ1 machine-automation CPU with 3 MB program memory and 0.5 MB retained variables
- Built-in EtherCAT master (up to 64 nodes / 2 servo axes) plus EtherNet/IP (up to 32 connections) and USB
- 1 ms primary task cycle, 2560 local I/O points (8960 with NX I/O), 40 units / 3 expansion racks
- IEC 61131-3 programming in Sysmac Studio (LD, ST, FBD, SFC); SD card slot for project and recipe backup
- SKU: NJ101-1000
- Series: Omron NJ-series Sysmac NJ1 CPU
- I/O: 2560 points
Best-Fit Applications
- Small packaging line where the NJ101-1000 runs sequence logic on EtherNet IP and runs two servo axes over EtherCAT for a 2-axis pick-and-place
- Benchtop test rig where the SD card slot holds the recipe set and the USB port programs from a laptop running Sysmac Studio
- Compact filling machine where 2560 local I/O points cover three CJ-series expansion racks and 6 virtual axes handle auxiliary tracking
Buying Checklist
- Pick the NJ101-1000 for a 3 MB Sysmac NJ1 CPU with 2 servo axes on EtherCAT and no DB / SECS functionality.
- Pick the NJ101-9000 instead when the machine only needs sequence control with zero servo axes.
- Pick the NJ301-1200 instead when the cabinet needs 8 servo axes and a larger 5 MB program on the same Sysmac tool chain.

FAQ for NJ101-1000
What is the Omron NJ101-1000 used for?
It is the CPU for a small Sysmac NJ1 machine. It runs the sequence program, executes up to 2 synchronous servo axes on EtherCAT, and exposes EtherNet/IP for HMI and remote I/O traffic. Typical fit is a single-machine line with one operator station.
NJ101-1000 vs NJ301-1200 — what is the difference?
The NJ301-1200 doubles the program memory to 5 MB, raises the synchronous motion axes to 8, and supports more connected units. The NJ101-1000 is the smaller and lower-cost fit when 3 MB of program and 2 servo axes are enough.
Does the NJ101-1000 have built-in EtherNet/IP?
Yes. It has one EtherNet/IP port that handles up to 32 connections, plus a separate EtherCAT master port for servo and remote I/O, plus a USB port on the front face for programming.
What software programs the NJ101-1000?
Sysmac Studio Standard Edition, sold as the SYSMAC-SE200D DVD or the SYSMAC-SE201L single-seat licence. The software covers ladder, structured text, function block and SFC, plus EtherCAT and EtherNet/IP network configuration.
What power supply does the NJ101-1000 need?
Either the NJ-PA3001 AC power supply (100 to 240 VAC in, 5 VDC 6 A + 24 VDC 1 A out, 30 W total) or the NJ-PD3001 24 VDC supply. The CJ-series PSUs cannot power an NJ CPU rack.
