1.4 ET 200X with pneumatic functionality
40 per cent of all actuators are pneumatic cylinders. Three expansion modules for
the pneumatic connection to the ET 200X are available for optimum adaptation of
the ET 200X to the overall process:
EM 148-P DI 4 DC 24V/DO 2 P expansion module (pneumatic module)
EM 148-P DO 16 P/CPV10 expansion module
(pneumatic interface module for FESTO valve island CPV10)
EM 148-P DO 16 P/CPV14 expansion module
(pneumatic interface module for FESTO valve island CPV14)
Pneumatic module
The pneumatic module is an expansion module with four digital inputs and
two separate 4/2-way valves. The pneumatic module is used to control:
a maximum of two double-acting pneumatic cylinders having a piston diameter
of up to 50 mm
a single-acting pneumatic cylinder with a piston diameter up to 50 mm when a
plug is used for the second connection to the valve
other pneumatic drives such as rotary actuators or
a nozzle.
Pneumatic cylinders having a piston diameter greater than 50 mm can similarly be
controlled with constraints at the piston speed.
The digital inputs can be used to acquire the limits of travel of the pneumatic
cylinders.
You can integrate up to seven pneumatic modules into an ET 200X.
