Kuhnke Airbox is a pneumatic plug-in module (Airbox) designed and manufactured by Kuhnke GmbH, often branded SIEMENS; which is used on AS-Interface bus systems in industrial automation. There are 3 designs and over 30 models.
It is the only pneumatic device which has been specifically designed for use on AS-Interface. A single housing incorporates 2 main pneumatic valves, 2 solenoid operated pilot valves, an integrated circuit board with AS-Interface ASIC, sensor input connections, indicators and diagnostics. The Kuhnke Airbox is designed to fit the Siemens standard K45 or K60 module bases.
The difference between each model is based upon whether yellow cable only is required or yellow and black cable. There are 2 types of exhaust to choose from and some models are available with ATEX certification. There are mono and bistable versions.
