Why EDS-508 is ideal for Industrial Control and
Automation
Advanced Network Control Function
¾Multicast traffic management—IGMP Snooping function provides the
ability to manage multicast traffic.
¾Network segment planning—The VLAN function not only helps to
segment your network without being restricted by physical connections, but
is also more secure, and protects against unwanted data transmission.
¾Traffic prioritization capability—Quality of Service (QoS) provides a
traffic prioritization capability to ensure that important data gets delivered
consistently and predictably.
Redundant Ethernet Ring Capability
¾Fast recovery time (< 300 ms)—Ensures that your automation system will
be back to normal in under 300 ms when the network gets disconnected.
¾Ring Coupling for Distributed Applications—To give you more flexibility
to separate one redundant Ethernet ring into several individual rings for
distributed applications.
Intelligent Network Management
¾Automatic relay warning and E-mail warning by user-configured
event—To provide the system manager with real-time and designated alarm
messages.
¾SNMP OPC Server with HMI/SCADA software—To let control engineers
monitor the network from a central location with existing and familiar
visualization and control applications.
¾Prevent unpredictable network traffic—To give you the capability to
restrict unpredictable broadcast and multicast network traffic.
¾Web-based management—To monitor the real-time status of your network,
and better plan your industrial communications system.
Industrial Grade Reliability
¾Extended operating temperature capability—To ensure that your Ethernet
equipment can withstand harsh environmental conditions (-40 to 75°C).

Introduction
1-3
¾Industrial strength safety regulations—To ensure that your Ethernet
equipment can withstand critical industrial applications, such as in hazardous
locations (UL/cUL Class 1 division 2 and ATEX Class1 Zone 2) and comply
with FCC, TÜV, UL, and CE Standards.
¾Long-haul transmit distance of 40 km or 80 km—To extend your
transmission distance to meet fully the application criteria of Transportation
Automation, Power distribution, and Utility Automation.

DIN-Rail Mounting
The aluminum DIN-Rail attachment plate should already be fixed to the back
panel of EDS-508 when you take it out of the box. If you need to reattach the
DIN-Rail attachment plate to EDS-508, 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 EDS-508 from the DIN-Rail, simply reverse Steps 1 and 2 above.
Wall Mounting (Optional)
For some applications, you will find it convenient to mount MOXA EDS-508 on
the wall, as illustrated below.

EDS-508 Hardware Installation Guide
2-4
STEP 1—Remove the
aluminum DIN-Rail
attachment plate from the
MOXA EDS-508 rear panel,
and then attach the wall
mount plates, as shown in
the following diagram.

Bottom
plate
STEP 2—Mounting MOXA EDS-508 on the wall requires 4
screws. Use the EDS-508, 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.
6.0 mm
3.5 mm
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 all the
way—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
in the wall, insert the four screw
heads through the large parts of the
keyhole-shaped apertures, and then
slide EDS-508 downwards, as
indicated below. Tighten the four
screws for more stability.

Chapter 3 Wiring MOXA EtherDevice™ Switch
This chapter includes technical information about connecting MOXA EDS-508
to an external power source and to an external alarm system, and shows you
what types of cables you should use for the Console port, Ethernet ports, and
optical fiber ports.
The following topics are covered in this chapter:

Wiring the Relay Contact
Wiring the Redundant Power Inputs
Wiring the Digital Inputs

Wiring Requirements
WARNING
Do not disconnect modules or wires unless power has been switched
off or the area is known to be non-hazardous. The devices may only be
connected to the supply voltage shown on the type plate. The devices
are designed for operation with a Safety Extra-Low Voltage. Thus,
they may only be connected to the supply voltage connections and to
the signal contact with the Safety Extra-Low Voltages (SELV) in
compliance with IEC950/ EN60950/ VDE0805.
WARNING
Substitution of components may impair suitability for Class I,
Division 2 and Zone 2. These devices must be supplied by a SELV
source as defined in Low Voltage Directive 73/23/EEC and
93/68/EEC.
WARNING
This equipment has been evaluated as EEx nC IIC T4 equipment
under DEMKO Certificate No. 03 ATEX 0324537U. Each module is
marked II 3G and is suitable for use in Zone 2 Explosive
Atmospheres. The device must be installed in a minimum IP 54
enclosure as defined in IEC 60529 and EN 60529.

Wiring MOXA EtherDevice™ Switch
3-3
ATTENTION
This unit is a built-in type. When the unit is installed in another piece
of equipment, the equipment enclosing the unit must comply with fire
enclosure regulation IEC 60950/EN60950 (or similar regulation).
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring
your MOXA EtherDevice Switch.
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.
You should also pay attention to the following points:
yUse 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.
yNOTE: 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.
yYou 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.
yKeep input wiring and output wiring separated.
yIt is strongly advised that you label wiring to all devices in the system
when necessary.

EDS-508 Hardware Installation Guide
3-4
Grounding MOXA EDS-508
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 Relay Contact
EDS-508 has two sets of relay output—relay 1 and relay 2. Each Relay Contact
consists of the two contacts of the terminal block on EDS-508’s top panel. You
may refer to the next section for detailed instructions on how to connect the
wires to the terminal block connector, and how to attach the terminal block
connector to the terminal block receptor.
In this section, we will explain the meaning of the two contacts used to connect
the Relay Contact.
Relay1 Relay2
Relay1 Relay2
FAULT:
The two sets of relay contacts of the 6-pin
terminal block connector are used to detect
user-configured events. The two wires
attached to the Fault contacts form an open
circuit when a user-configured event is
triggered. If a user-configured event does
not occur, the Fault circuit will be closed.
