Input Power Requirements
The ADAM-6200 system is designed for a standard
industrial unregulated 24 V
DC
power supply. For further
applications, it can also accept +10 to +30 V
DC
of power
input, 200mV peak to peak of power ripple, and the
immediate ripple voltage should be maintained between
+10 and +30 V
DC
.
Application Wiring
Isolated Digital Input
Dry Contact
Wet Contact
Isolated Digital Output
Overview
Thank you for purchasing this ADAM-6200 series
module.This is a quick guide to help you deploy the
ADAM-6200 series module in your application eld. It
will include power and application wiring. If you need a
more complicated or specic installation, you could try
to contact ADVANTECH for advanced technical support
or suggestions.

Daisy Chain Limitations
Here are the limitations of daisy chain connection with
auto-bypass protection enabled.
Read the following statement carefully before
installation.
In general, the maximum cabling distance of each
100BASE-TX network segment is 100 meter. Based
on this limitation, the maximum total connection length
in daisy chain wiring should also be 100m as if auto-
bypass protection active. See the following gure as
example, the distance from rst to second module is
50m, so as second to third. When the power fails on
second (middle) module, the auto-bypass will activate to
bridge the network connection. The total distance from
rst to the 3rd will become 100m, that means the total
network segment is close to limitation.
Furthermore, for the reason of signal transmission
characteristics, the continuous auto-bypass node should
be less than 2, so that the network communication in
daisy chain wiring is workable.
The purpose of the auto-bypass protection is to help user
minimize the damage situation of module power outage.
Note that when a power outage occurs on ADAM-
6200 modules, there exists around 2.5 seconds buffer
time for internally switching to auto-pass circuit.That
means Ethernet packets can’t reach the other devices
by daisy-chaining after this power-down module in
around 2.5 seconds.The valid connection duration after
the auto-bypass function is enabled is at most around
4 days, otherwise, the Ethernet communication will be
interrupted until power is restored.
