Introduction
The W&T Web-IO Analog-In/Out models include all the
functions in a single box for capturing your analog
measurements (0..20mA or 0..10V), tunneling them through the
network, saving and displaying them. A variety of alarm
functions are also available which can be custom added to your
own applications or into existing systems.
This manual contains all the information you need for
installation, configuration and operation of the Web-IO Analog-
In/Out devices..

1 Quick-start, Commissioning
To start up the W&T Web-IO Analog-In/Out and make it visible
in your network only a few steps are necessary.
1.1.1 Connect to power
If you want to use a power supply, connect 18-48V DC or 18-
30V AC to the screw terminal provided. Polarity is uncritical
when connecting AC power supplies. When connecting DC po-
wer supplies please note the polarity as indicated on the screw
terminal adapter:

W&T
To use the W&T model 11020 power supply, screw the power
supply plug into the screw terminal adapter:
1.1.2 PoE supply
The Web-IO Analog-In/Out can be used in PoE (Power-over-
Ethernet) environments in accordance with IEEE802.3af. The
supply voltage is provided then by the network infrastructure
through the RJ45 terminal. The device supports both phantom
power using data pairs 1/2 and 3/6 as well as power on the unused
wire pairs 4/5 and 7/8.
To enable power management for the supplying components, the
W&T Web-IO Analog-In/Out is identified as a Power Class 1 device
with a power consumption of 0.44 to 3.8W.
As an alternative to PoE the device can also be powered externally
using the screw terminal located on the underside of the device.
!Use of the W&T Web-IO Analog-In/Out is also possible in
networks wihtout PoE. In this casde simply use an external
power supply with the screw terminals as described above.
No additional configurations or settings are necessary.

1.2.1 Wiring the in- and outputs
Depending on the configuration the W&T Web-IO Analog-In/Out
can be wired as follows, whereby Ports 1 and 2 are indicated by
an „X“. The configuration is identical for both ports:
1.2.2 Current input 0..20mA, passive (#57661)
1.2.3 Current input 0..20mA, active (#57661)

10
W&T
1.2.4 Current output 0..20mA (#57661)
1.2.5 Voltage input 0..10V (#57662)
1.2.6 Voltage output (#57662)
The voltage output must be jumpered to the Sense input, which
can be used to measure and regulate the output voltage. This
jumper can be made either directly on the device or at the remote
end. For longer cable distances the jumper should be made on the
remote end so that fluctuations are automatically compensated for.
