5.2 Field modules
There are three designs available as standard field modules in protection
class IP67:
Flat housing with M12 connector (G2 design)
Field modules with cable glands (G4 design)
Compact modules with M8 connector (G6 design)
In the G2 series with M12 connector, the cable as well as the module can
be quickly exchanged in case of failure without requiring an electrician. The
flat cable can be inserted in two directions, making cable layout simpler. An
addressing jack makes the module easy and quick to address using the
VBP-HH1 hand-held. Due to its small height, this series is well-suited even
when space is short.
Communications are monitored and in case of failure, the outputs can be
powered off. Devices in two sizes (4 ports/8 ports) and in PNP or NPN versions
are available. Dual sensors or 4-wire sensors can be connected directly
to the module with 2 signal inputs on an M12 connector. In most G2
modules, the inputs from pin 2 and pin 4 are bridged from two neighboring
spots for this reason. If only one signal input is to be used, however, a threestrand
connector cable should be used.
The G4 series, in two sizes for the input and input/output module, already
include the cable entry glands. An already completed wiring job is thus particularly
simple and cost-effective to extend.
Connection is performed using cage-clamp terminals, which require no
strand end sleeves. For connection to the AS-Interface flat cable, the
U-G1F base (AS-Interface only) is required for the input modules, and the
U-G1FF base (AS-Interface plus external power supply) is required for the
input/output modules.
For address configuration, the modules can be plugged directly into the
handheld. If the U-1GFA or U-1GFFA based with addressing jacks are
used, they can also be addressed through the base. Round cables can also
be used for the AS-Interface cable. In this case, the U-G1P or U-G1PP base
is required.
There are versions available for contact and two-wire sensors, for NAMUR
sensors as per IEC 60947-5-6, and for three-wire sensors in PNP or NPN
technologies.
The G6 series, in two sizes (4 ports/8 ports), is a good choice when space
is at a premium (robotics or handling systems). By using M8 plug connectors
to connect sensors, compactness and flexibility can be combined.
Using the VAZ-2T5-G2 splitter box, up to five G6 compact modules can be
connected via one M12 connector cable, which is also used for address
configuration. If only a few G6 modules must be connected, this can also be
done using a VAZ-2T1-FK-1M-PUR-V1-W simple junction box.
The short circuit protected inputs supply the sensors with max. 200 mA.
Contacts or two-wire sensors can also be connected, using Pin 4 (Signal)
and Pin 3 (GND). A maximum of 0.5 A per output and 2 A per module is allowable.
The modules provide communication monitoring as well as a function
display for the bus, external auxiliary power, and the inputs and outputs.
