Programmable Millenium relays from Crouzet

Date of publication: 09-02-2026 🕒 3 min read

This week we recommend to our customers new Millenium series logic controllers from Crouzet.

The new Millenium relays are the result of over 20 years of experience in manufacturing previous generation controllers, such as the well-known Millenium 3. Combined with simple and intuitive Crouzet Soft software, the new logic controller from Crouzet is the ideal solution for small automation projects.

The recommended range includes three product groups. The first are the relays themselves, which are PLC devices mounted on a DIN rail, capable of handling various loads through digital and analog inputs/outputs (voltage and current), including direct control of circuits using relays (optionally in a semiconductor version, SSR). The module is programmed via Ethernet network (standard RJ45 connector) and a built-in server. Selected models have a keyboard and a clear, backlit LCD display.

Programmable Relay

Expansion Module

Communication Interface

The second group of products are expansion modules offering additional input and output contacts (up to 8 units). The third are communication interfaces that allow further integration of the controller with the existing system through support for additional transmission methods, such as ModBus and RS485 standards. An alternative expansion allows logging the operation of the controller (state max. 24 channels) on a microSD card.
