ADAM-4520A Startup Manual 1
Before you begin installing your module, make sure that the
following materials have been included:
• ADAM-4520A
• 1 x DIN-rail mounting bracket (attached to module)
• Startup Manual
• 1 x Panel mounting bracket
If any of the above items are missing or damaged, please
contact your distributor or sales representative immediately.
CE Notication
ADAM-4520A, developed by Advantech Co., Ltd. has
passedtheCEtestforenvironmentalspecications.The
test conditions for passing include the equipment being
operatedwithinanindustrialenclosure.Therefore,inorder
to protect the ADAM module from being damaged by ESD,
we strongly recommend the use of CE-compliant industrial
enclosure products.

Power Supply
ADAM modules are designed to accept industry standard
+24 VDC unregulated power. Operation is guaranteed when
using any power supply between +10 and +48 V
DC
. Power
ripples must be limited to 200 mV peak-to-peak while the
voltage in all cases must be maintained between +10 to +48
V
DC
.Allpowersupplyspecicationsarereferencedatthe
moduleconnector.Thepowercablesshouldbeselectedac-
cording to the number of modules connected and the length
of the power lines. When using a network with long cables,
we advise the use of thicker wire to limit the line voltage
drop. In addition to serious voltage drops, long voltage lines
can also cause interference with communication wires.
Communication Wiring
We recommend that shielded twisted-pair cables that com-
ply with the EIA RS-485 standard be used with the ADAM
network to reduce interference. Only one set of twisted-pair
cablesisrequiredtotransmitbothdataandRTSsignals.
Basic Conguration Hook-Up
Before placing a module in an existing network, the module
shouldbeproperlycongured.Thetwofollowingdiagrams
show typical layouts for both modules.
