Controller Provide Precise Positions

| Editor: Wolfgang Ernhofer

The Festo position controller CMSX for double-acting quarter turn actuators is economical and reliable. Its strengths come into their own in particular in areas where there is no explosion hazard.

A unique feature of the controller is the ability to provide a pre-definable safety position for the process valve. In addition to energy-efficient operation, further key features of the position controller CMSX are its interesting price/performance ratio and the high level of process safety it offers. This is ensured by its analogue and digital feedback signals and definable positions. The end positions can be defined flexibly via freely configurable analogue signals.

In the standard variant of the position controller, its micro controller continuously displays these feedback signals. In closed-loop mode, it continuously compares the setpoint signal with the actual position of the quarter turn actuator. Any deviations automatically trigger an error message and an emergency stop. If there should be a power supply failure, the process valve can be brought to a previously specified safety position, thus minimising otherwise incalculable process risks.

Anyone who has an aquarium knows how difficult it is to keep the water quality at a consistently high level. The principle of "The larger the pool, the more stable the water values" stands and falls with the number and size of the animals living in it.
