EZ Intelligent Relay
Product Focus
Easy operation
with maximum benefits
The Eaton EZ intelligent relays provide basic
functions that users could only implement
previously with individually installed and wired
devices. The EZD multi-function displays offer
powerful visualization functions.
Because of the extensive EZ
product range, users can
always find the best solution
for their needs. Solutions can
be as simple as a compact
stand-alone intelligent relay
with a few timing relays and
a timer switch, or as complex
as a large-scale network of
EZ intelligent relays that are
processing several hundred
2
I/O with local and remote
expansion modules and graphic
visualization. The need for
user-friendly operation and
programming is consistently
met and forms the basis for
the outstanding features found
in the EZ family of products.
Eaton’s EZ line really is
easy to use. In association with EZD, it offers
everything you need
from a state-of-the-art
automation system:
flexible networking,
local and remote
expansion modules,
visualization, scalability.
Simplicity and
user-friendly operation
EZ and EZD products are
known for their user-friendly
operation and programming.
Every rung or circuit connection
is wired just like you remember:
Contact – Contact – Contact –
Coil – Done! The devices allow
the “wiring” of 128 or 256
rungs or circuit connections.
Series and parallel connections,
which make up a major part
of a control circuit, are easily
created without previous
programming knowledge.
Ready-to-use function blocks
are simply integrated in the
wiring with coils, and contacts
are provided for additional
functions.
Everything needed is built-in
Depending on the device
selected, EZ and EZD products
provide users with timing
relays, flash relays, counters,
comparators, timer switches
and other ready-to-use functions.
The circuit diagram display of
serial and parallel connections,
unlike the display of AND and
OR operations in a function
block diagram, offers a more
manageable display of the
circuit. Every EZ and EZD
intelligent relay features an
integrated power flow display
to ensure safe operation during
commissioning and helps
identify errors in the circuit
diagram. For ease-of-use,
energized rungs are highlighted,
and non-energized rungs are
dimmed.
Security means safety
The finished circuit diagram is
stored internally and can also
be saved externally on a
memory module (EEPROM)
for transport, security and
backup. Multi-level password
protection secures your circuit
diagram from unauthorized
viewing, editing, copying or
deleting.

EZ800 and EZD
intelligent relays
The EZ800 and EZD intelligent
relays provide expanded
capabilities. Users can network
up to eight modules to easily
support applications with over
300 I/O points. A control
system can be designed by
using a single local program or
by using several programs on
different distributed devices.
Up to 1000 meters can be
covered by the network. The
intelligent relays can also be
easily integrated with higherlevel automation networks
such as PROFIBUS-DP,
CANopen, DeviceNet and
AS-Interface.
EZD multi-function display
The EZD supports all of the
functions of the EZ800 and
provides a full graphical display.
It replaces the 7-segment
display and indicates fault
messages and operating steps
graphically or in plain text. The
function buttons on the EZD
can be used to display and
modify set points during
operation. High-speed signal
counting, frequency measurement and incremental encoder
processing can all be seamlessly
implemented with an EZ800 or
an EZD.
5
Communication made easy.
Simple and inexpensive networking.
EZ-NET
By integrating the EZ-NET
network, which allows up to
eight stations consisting of
EZ800 or EZD devices,
communication can be
accomplished up to a distance
of 1000 meters. It does not
matter if the devices involved
are running their own programs
or are only used as remote
input/output modules.
6
Furthermore, all stations can
be expanded locally using the
EZ-LINK interface. This enables
EZ and EZD devices to be
used seamlessly with
applications involving 12 to
more than 300 I/O points.
The EZD also features the
option of a simple point-topoint connection with an
EZ800 or another EZD
via a serial interface.
Communication modules are
available that allow EZ and
EZD intelligent relays to be
connected to AS-Interface,
PROFIBUS-DP, CANopen and
DeviceNet network systems.
Communication modules
provide automation interaction
Communication
connections to the
production process
give more flexibility
and control.
Commanding, signaling,
monitoring and controlling
on bit level
A network connection is often
worthwhile for simple operating
steps often found in production
processes. The Actuator-Sensor
Interface, or AS-I, can provide
31 slaves simultaneously with
248 binary data items. For
machine building applications,
AS-I is the optimal network
connection choice because
input/output data can be
transferred with a very fast
reaction time of only 5 ms.
As a result, it is possible to
start up several motors
simultaneously in a materials
handling application.
The EZ205-ASI communication
module makes network
connection easy. It can be
connected via the EZ-LINK
connection to all expandable
EZ units. The two-wire AS-I
cable is simply wired to the
module– that's it! Data
exchange is then organized
by a higher level AS-I master.
Transferring complex data
More powerful fieldbus systems
like the PROFIBUS-DP are
used for complex automation
tasks. These may involve
transporting large data sets,
such as several analog values,
setpoints, counter states or
timer parameters. With
PROFIBUS-DP, up to 20 bytes
of data per station can be
transferred with each scan,
and up to 126 nodes can be
linked together over a distance
of 1200 meters. The EZ204-DP
gateway makes EZ intelligent
relays more flexible and
powerful. Entire parameter
sets of EZ can be read or
exchanged by a network
connection. If recipes require
different parameter sets to be
transferred to EZ, clock times,
counter states, setpoints and
actual values can be controlled
by a suitable master on this
powerful network system.
Connection to world
standard fieldbus systems
Similar to the EZ204-DP,
the EZ221-CO network
communication module for
CANopen and the EZ222-DN
for DeviceNet offer the same
functions.

IP65 protection
The EZD-CP4-500 or
EZD-CP4-800 supply
and communication
module can be combined
with an EZD display
and EZ intelligent relay
providing users with
the option of using a
stand-alone display

available: EZD-CP4-500 is used
with all EZ500/700s and the
EZD-CP4-800 is used with all
EZ800 and EZD-CP8 devices.
Plug & play technology allows
users to connect an EZD
display (EZD-80 or EZD-80-B)
to an EZ intelligent relay via an
EZD-CP4 supply and
communication module.
The EZD-CP4 module is
factory shipped with five

When an EZD display is directly
connected to an EZD-CP8 with
optional input/output modules,
the EZD becomes a compact
HMI control device. It combines
the functionality of an EZ800
with powerful visualization
functions. The two modules
are simply plugged together.

By connecting an EZ618-AC-RE,
EZ618-DC-RE or EZ620-DC-TE
expansion module, users can
create an intelligent relay with
24 inputs and up to 16 outputs.
These three expansion modules
are simply fitted onto the EZ
controller and directly connected
using the EZ-LINK interface
connector.
Alternatively, a connection can
be set up using the EZ200-EZ
coupling module and a 2-wire
cable allowing an expansion
module to be remotely mounted
up to 30 meters away.
The EZ202-RE expansion
module provides two additional
relay outputs that can be
connected directly using the
EZ-LINK connector.

EZSoft the user-friendly
circuit diagram editor
EZSoft makes things particularly
easy for users. The graphical
editor shows the circuit diagram
immediately in the display format
required. Selection menus and
drag & drop functions simplify
circuit diagram creation. Simply
select contacts and coils and
connect with the mouse –
that's it!
In addition to the editing
functions, the scaled software
packages EZSoftBasic and
EZSoft are available for
straightforward circuit diagram
input. All software includes
user-friendly menus and Help
screens.
EZSoft offers the following
display formats for viewing,
editing and printing out your
program:
• IEC format, with contact
and coil symbols using
international standards
• EZ circuit diagram, same as
what is seen when programming from the EZ front panel
• ANSI format, in compliance
with American standards
EZSoft supports users who are
configuring, programming and
defining parameters for EZ
intelligent relays and creating
visualization functions for EZD
displays. When intelligent relays
are connected to EZ-NET, all
connected devices can be
accessed and their programs
loaded from a single intelligent
relay.
The integrated offline simulation
tool allows users to test the
functionality of the circuit
diagram before commissioning,
without the need for a connected device. The comment
function for contacts, coils and
function blocks helps provide a
clear overview of the circuit
diagram. A cover sheet with a
customized company logo and
different text fields, as well as
the cross-reference list with
comments, can turn printouts
into the perfect documentation
for applications.
EZ is maintenance-free
The finished program is
stored in EZ's non-volatile
memory until modified.
Additional auxiliary power or
batteries are not required. The
intelligent relays are entirely
maintenance-free.
Circuit diagrams and parameters
are saved in the event of a
power failure. If a power failure
occurs, the EZ controller
stores switch positions and
values such as operating
hours, meters, counters and
timing relays. When power is
restored the values are
restored. This retentive feature
for the different function
blocks and data is available on
all EZ intelligent relay models.
