Introduction
The W&T Web-IO provides the ability to monitor and set 12 di-
gital inputs and 12 digital outputs using Ethernet TCP/IP.
The digital inputs are galvanically isolated in groups of 4 each and
can be driven with +/- 30V.
The outputs are current sourcing and can be fed with 6 - 30V
thorugh a common voltage input. UP to 500mA per output can
be switched. The individual outputs have thermal overload
protection and are short circuit protected. The outputs can be
wired in pairs or in parallel in groups of 4 outputs each to
achieve higher switching currents.
The Ethernet interface is configured as 10/100Mbit
autosensing.
The following TCP/IP protocols are available for reading and
setting the in- and outputs:
HTTP Simple user interface in the browser window
TCP Direct socket access from your own applications
UDP Direct socket access from your own applications
SMTP Alarm triggering via e-mail with configurable input
conditions
SNMP Incorporation into management systems and
alarm triggering via SNMP trap
Box-to-Box
Paired linking of Web-IOs
Configuration of the Web-IO can be performed via Web-Based
Management manually in the browser window or loaded using
an XML file.
The 12X Digital Web-IO can be powered with 12-24V AC or DC
connected to screw terminals. Alternately the included plug-in
power supply can be used for 230V operation.

Web-IO #57630
12xDigital-IO <-> 10/100BT
Connect a supply voltage of between 12 V and 24 V AC or DC
to terminals 1 and 2.
Compatible power supplies can be obtained as an accessory
from W&T. See http://www.wut.de Products & Downloads >>
Web-IO Digital.
After approx. 2 sec. a beep will sound and the Status and Error
LEDs should have turned off. If the red Error LED flashes, check
the network connection.
1If the WEB-IO has no IP address or address 0.0.0.0, the
on error and system error LEDs remain on after a reset
or new start! The LEDs will turn off only if an IP address has
been assigned.
