AS-Interface slaves
Intelligent sensors/actuators
Either "intelligent" sensors/actuators with integrated AS-Interface chip, or
modules, are connected to the masters/gateways. Pepperl+Fuchs offers a
wide range of "intelligent" sensors.
Modules
Modules are AS-Interface stations to which standard sensors/actuators can
be connected. AS-Interface modules are available as a control cabinet solution
and as field modules with protection to IP67. Analogue values with up
to 16 bits can be automatically transferred to the higher level field bus via
analogue modules within a max. of 35 ms.
The control cabinet modules in the KF and KF2 series are 20 mm or
40 mm (4EA modules) wide and offer plug-in terminals as well as power rail
connections for fast, simple installation in the control cabinet. These KF
modules are only available as standard slaves in specification 2.0. The
newer version in the KE series is available as an A/B slave according to
specification 2.1.
The terminal housing module in the K3 series is flat (39 mm) and thus tailored
to terminal housing requirements. The outputs are supplied externally
and 3-wire sensors can also be connected. The KE1 series, which is only
50 mm high and 22.5 mm wide, offers connections for up to 4 two-wire inputs
and 2 externally-supplied electronic outputs.
In the case of the field modules the G2 series is available with a plug-in
connection via M12, the G6 series with a plug-in connection via M8 and the
G4 series with cable gland and cage-clamp terminals in different housing
sizes.
Connection of the G2 modules is achieved directly by attaching the flat AS-
Interface cable in the respective base portion. In the G4 series it is possible
to make the AS-Interface connection via round cable. Series G6 is connected
via a 4-pin M12 plug connector 4 (AS-Interface and 24 V auxiliary power).
Analogue modules for switching cabinet and field use transmit analogue
input and output values for current and voltage as well as the analogue values
from PT100 thermocouples without additional programming. In this
case it is necessary to use a master/gateway to Specification 2.1.
G5 series modules are in the device category (1)2G and are therefore approved
for hazardous areas in Zone 1 in accordance with ATEX. The AS-
Interface cable is therefore installed in increased safety and the connection
is carried out in accordance with EN 50019. The module electronics are encapsulated
and intrinsically safe inputs and outputs are available. NAMUR
sensors in accordance with the requirements of IEC 60947-5-6 (DIN 19234,
NAMUR) can be connected to the inputs.
Safe modules are available in the G4, G2 and KE1 versions for field and
junction box or control cabinets. The devices are TÜV-certified according to
EN 954-1 and IEC 61508.
Further information can be found in the chapters on the modules.
