ISOLATION
DIAGRAM
TRANSFORMER
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
if module is in default mode
and stays ON if an input is out
of range.
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 input circuit, network, and
power circuit are isolated from
each other for safety and noise
immunity.
