The VAA-4EA-G4-ZE/E2 is an AS-Interface
coupling module with four inputs and four out-
puts. Mechanical contacts and 2- and 3-wire
sensors can be connected to the inputs. The
sensors are supplied via the module. The out-
puts are electronic outputs, which can be loa-
ded to 24 V DC and 2 A per output (total load <
4 A).
The IP67 rated G4-PG module is especially
suitable for rough conditions. Sensors and ac-
tuators attach to PG cable glands and cage
tension spring terminals thus making the instal-
lation especially user-friendly. For pre-addres-
sing the module it can be plugged directly onto
the adapter of the hand-held programming de-
vice VBP-HH1.
The current switching state of each channel is
indicated by an LED, located on the module's
top side. In the case of communication errors
on the bus, the outputs are de-energised via an
integrated watchdog, which can be deactivated
by the parameter bit P0.
Both flat and round cables can be used for the
AS-i transmission line and the external
24 V DC power supply. Use the U-G1FF base
for the AS-i flat cable. The AS-Interface stan-
dardised EEMS interface, uses the cable pier-
cing method to connect both the yellow and
black flat cables.
Use the U-G1PP base for the round cable. The
AS-i-cable as well as the external power supply
may be connected within this base.
