EtherStax ES2000 Series
Rugged, Stackable Ethernet I/O
EtherStax I/O blocks provide a ruggedized, high-
density solution to interface many analog and
discrete signals to your control system.A stackable
aluminum housing maintains a small footprint and
stands up to industrial environments. The Ethernet
interface supports Modbus TCP/UDP/IP for reliable
host data transfer or peer-to-peer communication.
Web-based configuration simplifies setup with
any web browser. For OEM systems, or those that
require specialized housings, an open-board version
without the enclosure is available. EtherStax are
ideal for a broad range of measurement and control
applications.
Rugged, Industrial-Grade Design
EtherStax are designed for high-reliability operation.
Units feature 3-way isolation and surge protection.
The I/O circuitry has over-temperature, over-
voltage, and over-current protection. Redundant
communication paths and DC power ensure
dependable operation. If network communication
is lost, outputs fail safely and a relay provides local
alarming or shutdown functions.
Stackable, High-Density I/O
A variety of models offer a mix of analog and
discrete I/O interfaces with up to 96 channels on a
single unit. Monitor sensors, control devices, or add
local alarms. The units interlock for secure stacking
that consumes little space when mounted on a
surface or DIN rail. .
Key Features & Benefits
■High-density industrial Ethernet I/O:
Put hundreds of I/O channels in less panel space.
■Stackable aluminum or open-board packaging:
Choose industrial-strength or low-cost mounting.
■Rugged, shock and vibration-resistant design:

■Ready for STP, RSTP, other redundancy schemes:
Supports dual-path communication via copper and
fiber.
■Local failsafe SPST 5A fault relay:
Provides alarm/shutdown if network or power fails.
■Surge suppression and 1500Vrms isolation:
Protects power, relay, I/O, and each Ethernet Port.
■Redundant DC power w/internal diode coupling:
For “bump-less” transfer to back-up power.
■Extended operating temperature of -40 to 70°C
■Designed for CE and UL/cUL Class1 Div 2 ABCD

Distributed I/O for Batch Processing
EtherStax I/O interfaces sensors, actuators, displays
and other instruments to a PLC, DCS, or PC over
your Ethernet network. Analog inputs monitor tem-
perature, level, flow, pressure, voltage, current, and
myriad process variables. Analog outputs control
drives, pumps, valves, motors, and heaters, or write
to displays and recorders. Discrete inputs detect
open/close and change-of-state while discrete out-
puts perform on/off control.
SCADA and Remote I/O
In addition to all the functions already mentioned,
EtherStax are ideal for supervisory control and data
acquisition at remote sites. Units tolerate -40 to
75°C allowing outdoor mounting. Flexible, redun-
dant power supports battery operation. Multi-media
capability enables use of copper, fiber-optic, or wire-
less Ethernet networks to eliminate the high cost of
leased lines.
Discrete Manufacturing
EtherStax models with high-density discrete I/O
provide a cost-efficient solution for automated
operations such as machining, assembly, and packag-
ing. These compact units can mount on machinery
without worry of electrical noise, high voltage surges,
or vibration affecting performance. EtherStax have a
high level of immunity and resistance to transient sig-
nals from solenoids, motors, and magnetic fields.
Ethernet-Enable your OEM Machinery
Make your machines Internet-ready with EtherStax
and monitor operation from any PC with an
Ethernet link. The rugged aluminum housing can bolt
directly to your equipment. Alternatively, the open-
board version can mount in a NEMA enclosure or
inside your machine. Resistant to shock and vibration,
EtherStax units provide dependable operation even
on moving machinery.

Ethernet I/O: EtherStax®Series
Easy Peer-to-Peer Communication with Acromag i2o®
i2o input-to-output messaging
Acromag’s i2o technology is the easy
way to transmit input values for
remote output without a PLC, PC or
master CPU.
With i2o, many Ethernet I/O modules have the
ability to operate like a long-distance transmitter.
You can convert your sensor inputs at Point
A to process control signals at Point B. Or,
you can monitor discrete devices at one site
by reproducing the discrete levels with a relay
output at another location.
Use your existing Ethernet lines
to save time and wiring expenses
Connect input modules to output modules using
your existing copper/fiber infrastructure or with
a single new cable. Multiple I/O modules can be
multiplexed through a switch or wireless radios.
No complicated controllers.
No software. No programming.
Acromag Ethernet I/O modules have a built-in
web page making it simple to configure using
your standard web browser. Just click a few
menu settings, enter the IP addresses, and you
are done. Fast and easy.
BusWorks 900EN Series I/O Modules
Up to 12 channels per module and
reliable, failsafe communication
Monitor up to a dozen devices with a single pair
of I/O modules. Discrete I/O modules have twelve
channels that you can set up as inputs or as
outputs in four-channel groups. This allows
bi-directional communication between two
modules. Analog input modules measure up to
six current, voltage, thermocouple, or RTD
sensor signals. This data is then transmitted to a
six-channel analog output module providing DC
current or voltage output signals.
Wire-saving applications
Our i2o technology lets an input module speak
directly to an output module. It is ideal for non-
critical projects that don’t need a PLC or PC
master. Reproduce remote signals based on
timed or event updates.

■ 96 discrete I/O channels:
Bi-directional channels support any
input/output mix in a single unit.
■ High-density stackable unit:
Stacked mounting puts a lot of I/O in a very
small footprint to save panel space.
■ High Speed Channel Updates:
Updates all 96 channels in 1mS.
■ Modbus TCP/IP or UDP/IP protocol:
I/O functions as slave to host controller.
■ Peer-to-peer i2o communication:
Inputs to one unit automatically update out-
puts on another over Ethernet link.
■ Change-of-state or timed updates:
Event-driven updates transmit data in less than
5mS between peers with i2o.
■ 10 Modbus TCP/IP sockets/sessions:
Multiple masters can talk to an EtherStax unit
at the same time.
■ Self-test checks I/O operation:
Test I/O channels from a web browser before
wiring terminals to devices.
■ Selectable input “wetting” current:
Internal current source eliminates pull-ups and
improves dry contact interface.
■ Automatic change of state detection:
Inputs detect quick momentary changes of
state that occur between polling.
■ Internal or external port excitation:
Selectable source on each 16-channel port
simplifies wiring and adds flexibility for use
with 5-28V DC logic.
■ Loop-back monitoring on all channels:
Inputs confirm output states for increased
system reliability.
■ Watchdog timers and failsafe outputs:
Communication fault sends output to a pre-
defined state or holds the last value.
■ Output open-load detection:
Output fault detection is selectable on indi-
vidual channels.
■ Thermal, current, voltage protection:
I/O is protected from excessive levels to reduce
downtime.
Open circuit board versions also available.

ES2151 Ethernet Analog Input/Output Modules
Description
These EtherStax I/O units provide a rugged, high-
density, and high-speed solution to interface
a large quantity of analog input signals. Units
accept 16 single-ended analog voltage inputs
and 16 single-ended current inputs. The ES2151
also provides 16 analog current outputs. Two
DB25 ports support an alternate interface of
voltage I/O from 8B input or output modules.
This combination of high-density analog inputs
and outputs is ideal for many sensor interface
applications in remote zones.
EtherStax units are built and tested for high reli-
ability and dependable performance in hostile
environments. Available in an aluminum enclo-
sure or as an open circuit board, both formats
stack vertically to maintain a very small footprint.

Ethernet I/O: EtherStax®Series
– 16 –
Description
These EtherStax I/O units provide a rugged, high-
density, and high-speed solution to interface
a large quantity of analog input signals. Units
accept 16 single-ended analog voltage inputs
and 16 single-ended current inputs. The ES2152
also provides 16 analog voltage outputs. Two
DB25 ports support an alternate interface of
voltage I/O from 8B input or output modules.
This combination of high-density analog inputs
and outputs is ideal for many sensor interface
applications in remote zones.
EtherStax units are built and tested for high reli-
ability and dependable performance in hostile
environments. Available in an aluminum enclo-
sure or as an open circuit board, both formats
stack vertically to maintain a very small footprint.
