QFLEX ISOLATOR
External supplies should produce regulated
12V DC with at least 100mA available for
each ISOLATOR that is to be supplied. KLARK
TEKNIK can supply or recommend a suitable
power supply.
If the VNET product is connected to the
ISOLATOR via its RJ45 connector then as
described above this will automatically
connect the power from the product's LINK
port to the ISOLATOR. This is not a concern
because ISOLATOR contains circuitry to prevent
any conflict with an external power supply.
configurations
For maximum flexibility ISOLATOR can be
used in a number of ways, below are some
examples :
1. Basic IN to OUT daisy-chaining with
additional branches as required.

2. Using only the Phoenix IN (or OUT) ports
allows the network wiring to be installed
and tested before other equipment
is installed.

3. ISOLATORs may be used to segment a large
network as convenient, protecting each
segment from the others. Note that using
them in this way does NOT allow the
network to exceed the 1 km total maximum
length limit.

4. Here multiple ISOLATORS are used to
create multiple backbones. As long as the
ISOLATORS are local to each other and the
controlling system, then each backbone may
be the full 1 km long.
