The Crouzet Millenium Slim is a groundbreaking ultra‑compact logic controller, recognized as the smallest in its class with a width of just 17.5 mm (0.69 inches). Designed for small‑scale automation and space‑constrained applications, it integrates the functionality of a PLC, timer, counter, signal converter, temperature controller, and data logger into a single pocket‑sized device. It can be mounted on a standard DIN rail or directly on a panel, thanks to its removable connectors.

Smallest Logic Controller Ever

The Millenium Slim measures only 17.5 mm in width — up to 4 times thinner than existing logic controllers. This minimal footprint allows it to be installed in control panels, electrical enclosures, or directly inside machines where space is at an absolute premium. Its ultra‑compact size does not compromise functionality; it still provides 8 highly configurable I/Os, data logging, and a real‑time clock with lithium battery backup.

Flexible I/O Configuration

The controller features 8 I/O points: 4 inputs and 4 outputs. The DC versions (CB8R and CB8S) offer exceptional flexibility with inputs that can be configured as digital, analog (0‑10 V), high‑speed counters, or PWM inputs. Outputs are available as either 6A relays (CB8R models) or 0.5A static transistors (CB8S models) with PWM capability. The AC version (CB8R) provides 4 digital inputs and 4 relay outputs, powered directly from 110‑240 VAC mains.

Wireless Connectivity & Free Software

Bluetooth is integrated into every Millenium Slim controller, enabling wireless programming, parameter setting, and program transfer from any PC or smartphone. There is no need for a programming cable or Ethernet connection. The free CrouzetSoft software provides an intuitive function block diagram (FBD) environment compliant with IEC 61131‑3 standards, with support for SFC (Grafcet). The free Crouzet Virtual Display app turns any smartphone, tablet, or PC into a remote HMI, allowing real‑time monitoring and parameter changes over Bluetooth.

Applications

The Millenium Slim is ideal for a wide range of small‑scale automation tasks, including outdoor lighting control, irrigation systems, heat pump management, building access control, HVAC monitoring, conveyor logic, and machine safety interlocking. Its ability to replace multiple devices (timers, counters, temperature controllers) significantly simplifies control panels and reduces component costs.

Software & Support

CrouzetSoft is available as a free download from the Crouzet website. It includes a library of pre‑programmed applications that can be quickly adapted to specific projects. The software supports online monitoring, program transfer, and configuration of all controller parameters. Crouzet also offers free technical documentation, application notes, and video tutorials to assist with deployment.
