THE Gemu 4221/4222 combi switchbox enables simple control and monitoring of pneumatic linear or quarter turn actuators used in processes for chemical, pharmaceutical or industrial engineering.
Normally open, normally closed and double acting actuators can be controlled via integrated 3/2 way pilot valves with manual override as standard.
An integrated travel sensor detects and transmits the valve end positions. Automatic programming is achieved using continuous valve travel detection that ensures quick commissioning without time consuming adjustment.
The position feedback to a PLS/PLC can be provided to various bus systems (such as AS-Interface or Lon-Works) or relay outputs.
Integrated LEDs enable optical position indication and performance control on site.
End positions and switch point differences can be programmed by software via a digital signal input so there is no need to open the housing.
The power supply is 24V or via bus system, which means time consuming wiring is no longer necessary.
The IP65 housing base is available in plastic or stainless steel and the housing cover is made from transparent plastic.
The 4221/4222 combi switchboxes are suitable for control of operating pressures from 2 bar to 6 bar and ambient temperature ranges from 0°C to 50°C.
