Metering Devices
Industry-Standard
Communication Protocols
Standard Modbus RS-485
Communication
Standard communication
includes an RS-485 output
speaking Modbus protocol.
This allows the unit to be
connected to any serial RS-
485 bus using the Modbus
interface. The unit
communicates easily with
most building automation,
Power Xpert Software or
other software systems.
Baud rates are up to
57.6K baud to provide
fast update times.
Wi-Fi or Land-Based
Ethernet
The unit offers an Ethernet
option—configured either as
an RJ45 or Wi-Fi connection.
The Wi-Fi configuration
allows the 150S/250S to be
used on standard Wi-Fi base
stations. The unit is assigned
an IP address; it
communicates Modbus
protocol over Ethernet TCP/
IP. Wireless Ethernet is
reliable and easy to integrate,
making it the superior
solution for mass meter
deployment.
KYZ Pulse
For applications in which a
pulse is needed, the unit also
provides a KYZ output that
pulses proportional to the
amount of energy consumed.
This feature is used for pulse
counting applications into
building management
systems where serial or
Ethernet protocol is not
available.
Verify Energy Bi lls
The IQ 150S/250S models
provide a traceable watthour
test pulse (used with a
watthour pulse recorder or
totalizer), so you can verify
the accuracy of your meter
and in turn, the accuracy of
billing from your utility
company and to internal
customers.
Integrated with Eaton’s
Power Xpert Architecture
IQ 150S/250S meters
integrate into Eaton’s Power
Xpert Architecture, where
meters, gateways and
monitoring devices
collaborate to create a
unified, centralized view of
the end-to-end power and
facility infrastructure.
When used in this
architecture, either with a
Power Xpert Gateway or
directly via Ethernet, the
meters with the Modbus RTU
option can provide Web-
based graphics of current
power conditions. Simply
connect your meter to a
Power Xpert Gateway to
translate Modbus-based
information from the meter
into HTML-based Web pages
that are accessible from any
standard Web browser. If you
select a model with the
Ethernet option, the meter
can easily be monitored
remotely via Power Xpert
Software or another third-
party monitoring system.
With access to accurate, real-
time information from IQ
150S/250S meters, Power
Xpert Architecture can
transform your power system
into an integrated, agile
system, and an easily
managed entity that performs
better and costs less.
Designed for the User
When space is at a premium,
yet you need ANSI C12.20
accuracy, Eaton IQ 150S/
250S meters fit the bill.
These ultra-compact meters
are ideal for surface mounting
next to a selected piece of
equipment for energy
monitoring. Requiring far less
space than other meters with
similar functionality, and
offering a
NEMA 12
enc
losure and a large, easy-
to-read faceplate, consistent
with other Eaton meter
models, these meters are
designed with “knockouts”
for easy retrofit installation.
Most meters in this class
have small or dark displays
that can be hard to see,
especially from a distance.
Eaton’s IQ 150S/250S meters
have a large, bright red, three-
line LED display, each line
more than a half-inch tall. This
display is very easy to read,
even if the meter is installed at
a height or distance. Using the
keypad and menus on the
local display, users can
display a variety of electrical
system values or program
the meter.
