The AirLINE Ex 8650 pneumatic valve block can be used to implement 3/2-way and 5/2-way functions for controlling process valves, single-action or double-action pneumatic cylinders, linear or rotary actuators, etc. The valve slices for air supplies of 300 l/min or 700 l/min act like digital output modules. They convert the electric control signals of the interface module into pneumatic output signals.

The valves themselves have a low power consumption and permit high pressures to be switched with short switching times. They are optionally available with or without manual emergency actuation. Versions are also available with a separate auxiliary control air supply for use in an extended pressure range or with a non-return valve for venting connections. The configuration can be individually adapted using optional baffle elements or pressure shut-offs.

The valve output modules provide up to 8 channels. This means up to 128 valve functions can be configured per station depending on the types of valve used.

The electronics modules of the valve slices display the modules status (group fault display) and the channel status (channel open/closed) on LEDs. Status, diagnostics and switching cycle counters of the channels can be read out via PROFIBUS.
