CJ2M-CPU3 /-CPU1


Since 2001, CJIM-series PLCs are in control of a wide variety of applications worldwide.
The accumulated experience and advancements in technology now result in CJ2M; fully compatible, yet fully new.

  1. Increased performance, and increased memory capacity
  2. Up to 40 I/O units on any CPU
  3. USB for plug-and-play access to the PLC

All models available with or without Ethernet port •Choice of serial port plug-in modules

  1. User-friendly programming, faster debugging

Features

  1. Five variations in program capacity from 5K steps to 60K steps; scale the CPU to your application needs.
  2. Faster processors; logic instruction execution time is reduced to 40 ns, floating point trigonometrics in less than 1 ps.
  3. Faster Function Block calls and execution, faster interrupt handling, less overhead time.
  4. Added execution memory for Function Blocks allows structured, object-oriented programming even in entry-level CPUs.
  5. General-purpose Ethernet port supports EtherNet/IP tag-based data links, connection to Support Software, communications between PLCs, FTP data transfers, and more (CJ2M-CPU3D).
  6. Standard USB port on all models allows Support Software to connect directly through standard USB cable.
  7. A Serial Option Module can be mounted to add RS-232C or RS-422A/485 communications ports (CJ2M-CPU3D).
  8. Compatible with all existing CJ1 power supply-, I/O-, control- and communication units.
