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.
The EZ intelligent relays bring timers,
relays, counters, special functions, inputs
and outputs into one compact device
that is easily configured. The EZ family of
products provides exceptional levels of
flexibility together with substantial savings in
commissioning time and effort.
The EZ intelligent relays are available in
more than 20 different styles that support
from 12 I/O up to 320 I/O points providing
the ideal solution for lighting, energy
management, industrial control, watering,
pump control, HVAC and home automation.
Once EZ products are installed, changes
are easily accomplished through front
panel programming, eliminating the need
to change wiring and wiring diagrams
increasing the savings realized.
Other terms often used for intelligent
relay are relay replacer, control relay and
smart relay.
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.
