Crouzet develops its own microcontroller

Crouzet has developed its own logic controller to replace the badged Mitsubishi product that it has been selling under the Millenium name for several years. The new model comes in four different guises, ranging from a bare-board version aimed at OEMs, through to an expandable model with a built-in backlit LCD display and 12 inputs and eight outputs. Intermediate versions have fewer I/Os, and dispense with the display, expansion capabilities and parameter-setting buttons.

According to Crouzet`s Brian Hornsby, it is the Millenium 2`s programming software that sets it apart from other similar relay-replacement products.

PC-based software allows users to drag-and-drop elements on the computer screen to create a program. Crouzet claims that it is the only controller on the market that allows users to mix logic functions with sequential flow chart blocks. The software comes with ready-programmed applications such as cam timers, pump rotation and DC motor speed control functions. The software can also simulate the program running, including a representation of the controller`s front panel display.

"The software makes the product what it is," says Hornsby. He adds that the program size of 128 function blocks is twice as large as similar controllers and suggests that the device "has the power to replace a small PLC".

The controllers will cost upwards of £80 in the UK. Crouzet has been selling about 30,000 of its previous Mitsubishi-badged controllers a year across Europe, putting it ahead of Mitsubishi itself (with sales of around 20,000) but behind Siemens (which sells around 250,000 of its Logo! controllers), Moeller (on 100,000) and Schneider (50,000). Hornsby hopes that new controller - which Crouzet does not plan to badge for other suppliers - will take it higher up the league.
