5.5 AirBox (Pneumatic Module)<br />
Actuators are used in many parts of a system. On average, more than 40%<br />
of them are pneumatic cylinders, controlled by compressed air. Long pressure<br />
hoses, however, results in too-long response times, too-thick hoses,<br />
unnecessary pressure losses and high costs when pressure lines must be<br />
moved. So-called valve-island solutions are only appropriate when very<br />
many valves must be driven in very little space. However, this is not always<br />
the case, and here is where decentralized control with pneumatic modules<br />
over <strong>AS</strong>-<strong>Interface</strong> shows clear advantages: fast response times, small air<br />
volumes, simple installation, flexible extensibility, and low cost. Test operation<br />
can be performed using manual operation without a PLC connection,<br />
and very little space is required. Up to 2 valves can be connected to a pneumatic<br />
module with 2 or 4 feedback inputs (max. 100 mA sensor power consumption).<br />
Devices with sinter filters (IP65) and with stainless steel air outlets (IP67) for<br />
the food industry, both monostable or bistable, are available.<br />
These modules can only be driven over the yellow <strong>AS</strong>-<strong>Interface</strong> or with an<br />
optional 24 V auxiliary power supply over the black flat cable.<br />
These modules cover the use of two independent 3/2-way valves each<br />
(three pneumatic inputs/outputs and two connection paths).<br />
