Trunk and drop
■ Very simple troubleshooting
■ A single device can be disconnected
without disrupting the network
■ Extra cable requirements result in higher costs
Mixed topology
■ Creation of logical groups results
in relatively simple troubleshooting
■ Popular method – ideal cost/benefit ratio
Connected in series
■ Difficult troubleshooting
■ Disconnecting a device interrupts the network
■ Lower costs due to fewer wiring components
The best I/O modules in the industry
Impressive features. Impressive functionality.
Impressive performance
Inputs with high density
All Balluff input blocks offer two input
points for each plug connector,
accessed via a V splitter.
Innovative housing design
The extra-flat profile reduces potential
dangers posed by cables. Rounded
corners offer highly visible locations
for channel markers. and two mount-
ing points are sufficient to secure the
robust metal housing.
Robust, full-metal housing
The fully encapsulated housing can
withstand impacts, shaking, corrosive
fluids, as well as people stepping on
it. All this and it costs no more than a
plastic housing.
Clearly visible status LEDs
Low-quality LEDs that are often
difficult to identify under demanding
production conditions perform poorly
when used in high-speed applica-
tions. Unlike Balluff status LEDs.
These are large, bright, highly visible
and provide maximum assistance.
Balluff quality will help you complete
setup and maintenance tasks and re-
duce machine downtimes with ease.
Powerful and
reliable outputs
With an output current of up to 2 A,
Balluff output modules are capable of
driving almost any load. Each output
also offers an overload protection
with LED indicator and a memory
feature for easy troubleshooting.
Display
A firmly entrenched part of the mod-
ule is a display that can be locked via
the PLC, which prevents unauthor-
ized access. Two LEDs controlled by
the PLC allow you to visualize results
that are not specific to the module or
port at the location where they occur.
