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.

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.
