With an intuitive web interface, comprehensive network services, and support for protocols such as OPC UA, MQTT, and REST, it is ideally suited for Industry 4.0 and the Internet of Things (IoT). This article highlights the technical features, application possibilities, and advantages of this versatile device designed for remote monitoring, building automation, and smart home integration.

Flexible Switching Channels for Complex Applications

The Web-IO 4.0 Digital, 16x In/Out features 16 switching channels that can be individually configured as inputs or outputs. This flexibility allows the device to be adapted to a wide range of requirements, whether detecting signals or controlling devices. The channels operate using 24V technology, with output currents up to 250 mA and short-circuit protection. With coupling relays, it is also possible to switch voltages of 12 V, 48 V, 110 V, or 230 V. Each input-configured channel includes an integrated 32-bit pulse counter for precise detection of events such as switches or pulses. The high number of channels makes this device particularly suitable for complex applications such as process monitoring, machine data acquisition (MDA), and fault monitoring, where both control and monitoring are essential.

Intuitive Operation and Network Integration

The Web-IO 4.0 Digital features a highly user-friendly, intuitive web interface, with language options in German and English. Users can control output-configured channels directly through the interface and monitor the status of input-configured channels in real time. The interface is optimized for smartphones, allowing mobile access anywhere. HTTP and HTTPS support ensures secure communications. Developers can access current I/O states using HTTP requests, AJAX, or JavaScript, allowing seamless integration into websites and applications. The box-to-box function enables 1:1 forwarding of switching signals over the network, simplifying remote control across multiple locations. These connectivity options make the device ideal for network-based control in connected environments.

Flexible Alarm and Notification Functions

The Web-IO 4.0 Digital offers extensive options for alerting and state signaling. Up to 30 actions can be configured to automatically trigger based on changes to inputs or outputs. These include email notifications, SNMP traps (V1, V2, V3), switching its own outputs, controlling outputs of another Web-IO, or sending HTTP requests to third-party devices. These functions are especially beneficial in critical applications such as remote monitoring or fault detection, where quick response is essential. The option to send state messages via email supports documentation and analysis of switching processes, which is crucial for audits and quality management.

Seamless Integration into Industry 4.0 and IoT

The Web-IO 4.0 Digital is fully equipped to meet the demands of Industry 4.0 and the Internet of Things. It supports modern communication protocols such as OPC UA, REST, and MQTT for easy integration into automation systems and IoT platforms. AMQP is also supported upon request. Additional interfaces such as SNMP V1, V2c, V3, Modbus TCP, OPC DA, Syslog, and Sensobase (ODBC database integration) ensure compatibility with existing systems and infrastructure. Developers can access I/O states directly via TCP and UDP sockets (client & server), allowing for custom implementations. FTP support enables device-side logging of switching signals, increasing process traceability. These connectivity features make the device a future-proof solution for building automation, home automation, and industrial use cases.

Data Logging and Time Management

The Web-IO 4.0 Digital includes an integrated data logger that stores switching events and state changes. Storage duration can range from a minimum of 7 weeks to up to 20 years, depending on the selected logging frequency (15 seconds to 1 hour). Data can be exported in various formats including FTP, Excel files, or email attachments, making further processing easy. An internal battery-buffered clock ensures accurate timestamps, further optimized by synchronization with a time server. These features offer reliable documentation and analysis of switching activities, which is especially beneficial for process monitoring and machine data collection.

Versatile Applications

The Web-IO 4.0 Digital, 16x In/Out is designed for a wide variety of applications. In remote monitoring and fault detection, it monitors inputs to detect and report operational errors. In building automation, it can control devices such as lighting, gates, or barriers and enable remote switching across sites. In smart home applications, it supports automation of lighting and heating systems to increase comfort and energy efficiency. In industrial environments, the device enables process monitoring, visualization, and machine data collection (MDA) to optimize production lines. The pulse counters on the inputs allow tracking of events such as production cycles or flow volumes. Additional use cases include access control and barrier management.

Flexible Power Supply and Standards Compliance

The Web-IO 4.0 Digital is powered via an external power source (12–24 V DC) through a screw terminal. This flexibility allows installation in various environments. The device is standards-compliant for both office and industrial use and offers high EMI resistance according to EN 61000-6-2, as well as low emissions according to EN 55032:2015 + A1 Class B, EN 61000-3-2, and EN 61000-3-3. These specifications ensure reliable and interference-free operation even in demanding environments.

Please note: A power supply is NOT included in the scope of delivery.

Durability and Reliability

The Web-IO 4.0 Digital is designed for continuous operation and comes with a five-year warranty. Its robust construction and DIN rail mounting support make it ideal for use in industrial environments. The internal battery-buffered clock ensures precise time tracking, which is further optimized by synchronization with a time server. These features underline the durability and reliability of the device even under challenging conditions.
