AS-Interface AirBoxes for pneumatics - System description

AirBox · Introduction
Decentralisation by means of the AS-Interface has also considerably marked and changed the field of pneumatics. For example in process technology there is a large variety of pneumatically driven ball valves and butterfly valves (quarterturn actuators) which are often still controlled conventionally, i.e. by means of solenoid valves and when AS-Interface is used by means of input and output modules. This conventional solution is also still often found in conveying and storage technology where linear movements, e.g. on lifting platforms, stoppers, shunts, and grippers are carried out. Pneumatic cylinders are used as drive elements and cylinder switches give feedback to the controller. This is where the AirBoxes come in. They combine electrically controlled pneumatic valves in a compact form and are controlled via the AS-Interface. This gives the word decentralisation a new meaning.

Quick connection
Time-consuming installation is not necessary any more due to the integrated tube connections which enable a secure connection and quick insertion and loosening without any tools. On the electrical side the AirBox can be integrated very easily into the existing AS-i network by means of the classic flat cable lower part. The AirBox is supplied electrically only via the yellow AS-i cable or additionally by means of the black flat cable so that the pneumatic outputs of the valves can be switched off separately with an e-stop. All AirBox variants have a manual override. This allows the user to carry out an initial pneumatic function test of the AirBox, without connection to the AS-i network. LEDs indicate switching states of the inputs and outputs and application of the operating voltage.
