Millenium Controllers

Crouzet New Millenium PLC

Crouzet has launched the New Millenium PLC,
an upgraded, compact logic controller designed
as a successor to the Millenium 3, featuring
built-in Ethernet, Modbus RS-485, and SD card
support.

It enhances connectivity with remote
web server access, offers expanded I/O (up to
60 points), and uses the intuitive Crouzet Soft
software for easier programming and migration.

Display or displayless options offer design flexibility
while reducing initial costs. Each controller has eight
input channels that can be ordered as eight digital channels
or a mix of four high-speed digital and four digital/analog
(4-20 mA) channels.

Key Features of the New Millenium PLC:

  • Connectivity: Built-in Ethernet (no extra module required) for web server, remote access, and Modbus RS-485 for enhanced communication.
  • Performance: Features twice the RAM of the previous generation, supporting larger, more complex programs.
  • Hardware Improvements: Enhanced, three-color customizable screen with improved navigation, plus an SD card interface for data logging and program transfer.
  • Scalability: Supports expansion up to 60 I/O points.
  • Software: Programmed with Crouzet Soft, which allows for easy conversion of legacy programs from Millenium 3.

Target Applications: Ideal for Small-Scale Automation

  • Allowing for both DIN Rail and Panel Mounting.

The New Millenium is designed to be highly versatile, combining the ease of use of the Millenium 3 with advanced, modern communication features.
