The pneumatic compact module is a highly integrated AS-Interface slave. As
an input/output module that is entirely suitable for field deployment, it has
four electrical inputs and two pneumatic outputs. The electrical inputs
behave in the same way as the inputs of the digital input/output compact
modules.
Both integrated pneumatic outputs are implemented by means of two pre-
set 4/2-way valves (2 to 8 bar; 550 Nl/min) with a shared compressed-air
supply and separate exhaust air collection and can be operated manually
using separate slide valves. Two cylinders that work in tandem, for example,
can be connected to a module in this range.
Connections to AS-Interface are made via the standard mounting plate. The
AS-Interface cable is inserted into the corresponding cable guides, and the
upper part is secured to the mounting plate by means of a screw. The mod-
ule is ready for use.
AS-Interface is the first system on the market that can transmit both stan-
dard signals and safety-related input signals (e.g. emergency stop) via the
same cable.
Only an additional safety monitor and safe modules are required to use AS-
Interface as a safety bus. This enables category 4 in acc. with EN 954-1 to
be achieved. A failsafe programmable controller or special master is not nec-
essary.
The concept and implementation of AS-Interface Safety at Work (AS-Inter-
face SaW) have been tested and certified by TÜV (technical testing associa-
tion).
This means that the system can be converted to the considerably more flex-
ible AS-Interface network, which is already available, thus obviating the
need for the complex, separately implemented emergency stop wiring that
has been necessary up to now.
