IMPORTANT SAFETY CONSIDERATIONS

You must consider the possible negative effects of power, component,

wiring, sensor, or software failure in the design of any type of monitoring or

control system. This is very important where property loss or human life is

involved. It is important that you perform satisfactory overall system design

and it is agreed between you and Acromag, that this is your responsibility.

The toggle switch is used to toggle the module into or out of Default Mode

(toggle left), or to reset the module (toggle right). In Default Communication

Mode, the yellow ST LED blinks slowly and the module assumes a fixed

static IP address of “128.1.1.100”, a default subnet mask of “255.255.255.0”,

a default username of “User”, and a default password of “password00”.

MOUNTING AND

DIMENSIONS

Unit mounts to “T” type DIN

rails (35mm, type EN50022).

Units may be mounted side-

by-side on 1-inch centers.

WARNING: IEC Safety

Standards may require that

this device be mounted within

an approved metal enclosure

or sub-system, particularly for

applications with exposure to

voltages greater than or equal

to 75VDC or 50VAC.

CONTROLS &

INDICATORS

Green Run LED is ON if power

is on and will blink in “wink” ID

mode.

Yellow ST LED blinks ON/OFF

slowly if module is in default

communication mode and

blinks rapidly if a watchdog

timeout has occurred.

Yellow I/O LED’s turn ON if

corresponding output switch is

closed, or input asserted low.

Green LINK LED ON if auto-

negotiation has successfully

established a connection.

Yellow ACT LED signals PHY

network Activity (busy).

ISOLATION BARRIERS

Dashed Lines denote isolation

barriers.

The I/O circuit, network, and

power circuit are isolated from

each other for safety and noise

immunity.

To Remove or Replace Factory Pullup Resistors…

Locate pullup resistor SIP’s installed in sockets of plug-in I/O board as

shown above. You must remove the right side cover and separate the two

boards to remove or install these resistors. 5.6K resistor SIP’s are installed

from the factory. Remove these resistors if I/O channels are pulled up

externally. Limit power in each SIP resistor to less than 0.5W.

When attaching the module to the

T-type DIN rail, angle the top of the

unit towards the rail and locate the

top groove of the adapter over the

upper lip of the rail. Firmly push the

unit towards the rail until it snaps into

place. To remove, first separate the

input terminal block(s) from the

bottom side of the module to create a

clearance to the DIN mounting area.

Next, while holding the module in

place from above, insert a

screwdriver into the lower arm of the

DIN rail connector and use it as a

lever to force the connector down

until the unit disengages from the rail

(do not twist the screwdriver to avoid

damaging plastic).

I/O PULLUP

RESISTOR

INSTALLATION

You must connect excitation

and/or install pull-ups for

proper I/O operation. I/O

terminals must not be left

floating.

5.6KΩ I/O pull-up resistors are

already installed from the

factory. You do not need to

refer to this information unless

you need to change or remove

these resistors.

If your application delivers

power to the I/O terminals

rather than the excitation

terminal, the internal pull-ups

should be removed to avoid

coupling current into adjacent

port channels.

MDI WIRING

The Ethernet port of this module is wired MDI and does not include

automatic crossover. The Ethernet port of your PC is also wired MDI and

may not include automatic crossover. As such, you must use a crossover

cable like that shown below when connecting this device directly to a PC.

Network

For 100Base-TX systems, at a

minimum, use data grade

Unshielded Twisted-Pair

(UTP) wiring that has a 100Ω

characteristic impedance and

meets the EIA/TIA Category 5

wire specifications.

It is recommended that you

use a crossover CAT-5 cable

to connect this device to your

PC.

For 10Base-T systems, you

may use Category 3, Category

4, or Category 5/5E UTP/STP

cable.

In either case, you are limited

to 100 meters between any

two devices.

A crossover cable simply

connects the differential

transmit pair on each end, to

the receive pair on the

opposite end.

Use a standard (direct) cable

when connecting to a hub or

switch port, which are

generally wired MDI-X.

Refer to the Accessory Cables section at the back of this manual for more

information on accessory cables including patch and crossover cables

available from Acromag and other vendors.

TIP: You can significantly enhance the EMI/RFI performance of your

network connections by using Category 5E STP cable (Shielded Twisted

Pair) with shielded RJ45 plug connectors. This will also help to protect your

installation from damage due to ESD (Electro-Static Discharge). The use of

shielded cable is strongly recommended for installations in harsh industrial

environments and/or in the presence of strong electrical fields.

You can use an Ethernet switch or switching hub to build a network of

Ethernet modules, similar to that shown below. This drawing shows how to

network-connect these modules to a 5-port Ethernet switch (Acromag Model

900EN-S005). Note that the 900EN-S005 switch includes automatic

MDI/MDI-X crossover and straight-through or crossover cable(s) may be

used, but it is generally not good practice to use crossover cables when

connecting to an auto-crossing switch.

Power

✓

Connect 15-36V DC to the power terminals labeled DC+ & DC-. Observe

proper polarity. For supply connections, use No. 14 AWG wires rated for at

least 75C. CAUTION: Do not exceed 36VDC peak.

CAUTION: Risk of Electric Shock –More than one disconnect switch may

be required to de-energize equipment before servicing.

✓Connect digital outputs to the output terminals. Refer to figures below:

IMPORTANT –Add Protection With Inductive Loads: Outputs already

include internal reverse-bias shunt diodes to help protect the output switch

from damage due to the high reverse-bias voltages generated when

switching inductive loads. You should add external protection near the

inductive load to prevent these transients from being sent along the

connection wires. Place a diode (1N4006 or equivalent) across an inductive

load with the cathode to (+) and the anode to (-).

Refer to the examples below for other types of output connections.

Note: Per UL, when the outputs are used to control interposing relays for

switching AC and DC devices of higher voltage/current, the coil ratings for

the interposing relay shall not exceed 24VDC, 100mA.

✓Connect Earth Ground as shown in the connection drawings above.

Additionally, connect the GND terminal (TB3-33) to earth ground.

The ground connections noted are recommended for best results. If

sensors are already grounded, use caution and avoid making additional

ground connections which could create ground loops.

The plastic module housing does not require earth ground.
