The standard controllers of the Millenium 3 family feature numerous modules such as cam controllers, angle-dependent cam controllers, pump or load management, memory modules, pressure and flow measurement, controllers (multi-point, PID analog or PWM), root extraction, sine, cosine, weighted averages, and much more. This is where Millenium 3 starts, where many small controllers stop, providing a cost-effective foundation for numerous applications: mechanical engineering, water supply, greenhouses, and water treatment are just a few examples. PWM or pulse width modulation is a cost-effective method for controlling heating and cooling processes, managing motors, or generating a voltage of 0 - 10 V/DC via a converter (cost-effective analog outputs). The analog inputs can process 0 - 10 V/DC and 0 - 24 V/DC.
