Overview

The EDS-205A/208A series of industrial Ethernet switches are entry-level

industrial 5 and 8-port Ethernet switches that support IEEE 802.3, IEEE

802.3u, and IEEE 802.3x with 10/100M, full/half-duplex, and MDI/MDIX

auto-sensing.

The EDS-205A/208A series provides 12/24/48 VDC (9.6 to 60 VDC)/18 to

30 VAC redundant power inputs that can be connected simultaneously to

a live AC/DC power source. The switches are available with a standard

operating temperature range from -10 to 60°C, or with a wide operating

temperature range from -40 to 75°C, and IP30 metal housing makes

them rugged enough for any harsh industrial environment.

To provide greater versatility for use with applications from different

industries, the EDS-205A/208A also allow users to enable or disable

broadcast storm protection with DIP switches on the outer panel.

The EDS-205A/208A switches can be easily installed with DIN-Rail

mounting as well as distribution boxes. The DIN-rail mounting capability

and IP30 metal housing with LED indicators make the plug-and-play

EDS-205A/208A switches reliable and easy to use.

DIN-Rail Mounting

The aluminum DIN-rail attachment plate should already be fixed to the

back panel of the EDS when you take it out of the box. If you need to

reattach the DIN-rail attachment plate, make sure the stiff metal spring is

situated towards the top, as shown in the figures below.

STEP 1:

Insert the top of the DIN

-Rail into

the slot

just below the stiff metal

spring.

STEP 2:

The DIN

-Rail attachment unit will

snap into

place as shown below.

To remove the EDS from the DIN-Rail, simply reverse Steps 1 and 2

above.

Wall Mounting (optional)

For some applications, you will find it convenient to mount the

EDS-205A/208A on the wall, as shown in the following figures.

STEP 1:

Remove the aluminum

DIN

-Rail attachment plate

from

the EDS-205A/208A’s

rear panel, and then attach

the wall mount plates as

shown

in the diagram at the

right.

STEP 2: Mounting the EDS-205A/208A on the wall

requires 4 screws. Use the

switch, with wall mount

plates attached, as a guide to mark the correct

locations of the 4 screws. The heads of the screws

should be less than 6.0 mm in diameter, and the shafts

should be less than 3.5

mm in diameter, as shown in

the figure at the right.

NOTE

Before tightening the screws into the wall, make sure the screw

head and shank size are suitable by inserting the screw into one

of the keyhole-shaped apertures of the wall mounting plates.

Do not screw the screws in completely—leave about 2 mm to allow room

for sliding the wall mount panel between the wall and the screws.

STEP 3:

Once the screws are fixed on the

wall, insert the four screw heads

through the large parts of the

keyhole

shaped apertures, and then

slide

the EDS-205A/208A

downwards

, as indicated. Tighten

the four screws for

added stability.

Wiring Requirements

WARNING

Safety First!

Turn the power off before

disconnecting modules or wires. The

correct power supply voltage is listed on the product label. Check

the voltage of your power source to make sure that you are using

the correct voltage. Do

NOT use a voltage greater than what is

specified on the product

label.

These devices must be supplied by a SELV source as defined in

the Low Voltage Directive 2006/95/EC and 2004/108/EC.

WARNING

Safety First!

Calculate the maximum possible current in each power wire and

common wire.

Observe all electrical codes dictating the

maximum current allowable for each wire size.

If the current goes above the maximum ratings, the wiring could

overheat, causing serious damage to your equipment.

- 10 -

You should also pay attention to the following points:

•Use separate paths to route wiring for power and devices. If power

wiring and device wiring paths must cross, make sure the wires are

perpendicular at the intersection point.

NOTE: Do not run signal or communications wiring and power wiring

in the same wire conduit. To avoid interference, wires with different

signal characteristics should be routed separately.

•You can use the type of signal transmitted through a wire to

determine which wires should be kept separate. The rule of thumb is

that wiring that shares similar electrical characteristics can be

bundled together.

•Keep input wiring and output wiring separated.

•It is strongly advised that you label wiring to all devices in the system

when necessary.

Grounding the EtherDevice Switch

Grounding and wire routing help limit the effects of noise due to

electromagnetic interference (EMI). Run the ground connection from the

ground screw to the grounding surface prior to connecting devices.

ATTENTION

This product is

intended to be mounted to a well-grounded

mounting surface such as a metal panel.

Wiring the Redundant Power Inputs

The top two contacts and the bottom two contacts of the 4-contact

terminal block connector on the EDS’s top panel are used for the EDS’s

two AC/DC inputs. Top and front views of one of the terminal block

connectors are shown here.

STEP 1:

Insert the negative/positive AC

/DC wires into the

-/V+ terminals.

STEP 2:

To keep the AC

/DC wires from pulling loose, use a

small flat

-blade screwdriver to tighten the wire-

clamp

screws on the front of the terminal block connector.

STEP 3:

Insert the plastic terminal block connector prongs into

the terminal block receptor, which is located on EDS’s

top panel.

ATTENTION

Before connecting the EtherDevice Switch to the

AC/DC power

inputs, make sure the AC/DC power source voltage is stable.
