Web-IO 4.0 Digital
IP relay for DIN rail mount from 24 to 230 V
Stand-alone and via integration into IoT, SCADA-, MES and NMS systems
With its broad range of supported protocols and access methods the Web-IO 4.0 Digital can be integrated into many existing systems with very little effort. And even stand-alone, released from the automation jungle, the Web-IO can take on a wide variety of detection and monitoring tasks.
Test models now*Features
-
Switching
Your smartphone can become just as much a switching center as your PC browser. Depending on the model the Web-IO switches with traditional 24V automation technology, with potential-free contacts, or 230V direct.
-
MQTT and REST
Because it supports MQTT and REST the Web-IO 4.0 is ideal for IoT solutions and Industry 4.0.
-
Sending alarms
A potential-free contact or limit value switch is sufficient for the Web-IO to inform the responsible persons in serious situations. Other alarm sending possibilties include SNMP trap, TCP messaging, MQTT Publish and more.
-
Modbus and OPC
As a TCP Modbus slave the Web-IO can be incorporated into traditional automation systems. Using the right configuration you can even bridge between Modbus TCP and IoT. In spring 2021 the Web-IO 4.0 with OPC UA will also fit into the very latest systems.
-
Industry ready
With DIN rail mount, 24V power and all the required approvals, the Web-IO 4.0 is ideally suited for industrial 24/7 application. This applies of course to the 230V models as well.
-
Additional protocols
Also possible is individual access via HTTP and HTTPS, TCP and UDP using simple API interfaces. In box-to-box mode switching signals can even be passed along without the use of any external systems.
Application examples
Here is just a small selection of possible applications using the Web-IO 4.0 Digital.
Additional Application examples find here.
-
Tunnel switching signals in the network
Switching signals from one location to another without having to route new cable. Simply use your existing network as the transmission path. -
Monitor and control in your browser
Benefit from the use of new web technologies: Use HTTP requests and AJAX to program your own dashboard. -
The Web-IO as FTP data logger
What was switched and when? Retain switching signals over time in a file. A potential-free contact is all you need to write a log file with time stamps via FTP. -
Limit value switch sends email
Many devices have switching outputs for example to switch on a warning light when a fault occurs. Use these contacts to let the responsible person know immediately via email.

The benefits at a glance
-
Fast setup
Connect, assign IP, configure in the browser, done!
-
Secure continuous operation
Industrial grade hardware, rugged operating system, low heat build-up
-
Low current consumption
Current consumption just 100mA at 24V – more efficient than an industrial PC or most controllers.
-
Test now for 30 days!
*No risk: commercial customers can also test Web-IOs for 30 days at no cost.
If the Web-IO doesn’t meet your needs, you can simply return it within 30 days.
Rely on flexibility and quality in equal measure with the network relay
When it comes to reliably transmitting digital switching signals, it is best to rely directly on high-quality digital IO components. With our "Web-IO" product line, we offer such Net-IOs, i.e. remote network switches, which are configured for use in a wide variety of systems. This makes the W&T network relays ideal for applications in a wide range of areas. The top-hat rail-mountable Web-IOs are available as switching actuators for 24 V DC voltage or for 230 V installation. Another advantage is the variety of supported protocols and software interfaces.
With our network relay, you can rely on all standard industry features
Our network relays offer you a wide range of common industry features. They come with the latest industry features and communication standards when you purchase the IO-Device, directly "out of the box". W&T Web-IOs natively support protocols such as MQTT, REST, OPC UA and Modbus TCP, making them ideal for secure Industry 4.0 and IoT applications. In addition, limit value switches (potential-free contacts) and (voltage) signal changes can trigger an automatic alarm via the inputs of the Net-IOs.
Network relays for industrial use
We supply you with network relays that are specifically designed for use in industry and automation technology. With top-hat rail mounting, 24 V or 230 V supply and the necessary conformity to the applicable industry standards, our Web-IO products are ideally equipped for operation in the control cabinet - and for 24/7 use. Modern API interfaces and encrypted access via HTTPS ensure secure communication.
