With an intuitive web interface, comprehensive network services, and 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, applications, and benefits of this versatile device, designed for remote monitoring, building automation, and home automation.

Precise Control and Monitoring of Switching Signals

The Web-IO 4.0 Digital, 12x In, 12x Out features 12 switching inputs in 24V technology, equipped with integrated 32-bit pulse counters to precisely capture events such as switching operations or pulses. The 12 switching outputs are digital outputs in 24V technology, operating with a current-driving capacity of up to 500 mA and are short-circuit proof. Through coupling relays, voltages of 12V, 48V, 110V, or 230V can be switched. These features enable the control of devices such as lighting, gates, or barriers, as well as the monitoring of sensors or switches in industrial and private applications. The high number of inputs and outputs makes the device particularly suitable for complex applications such as process monitoring, machine data acquisition (MDA), and fault signal detection.

Intuitive Operation and Network Connectivity

The operation of the Web-IO 4.0 Digital is extremely user-friendly, thanks to its intuitive web interface, which can be switched between German and English. Users can control the switching outputs directly through the web interface and monitor the state of the switching inputs in real time. The interface is optimized for smartphones, allowing control even while on the go. Support for HTTP and HTTPS ensures secure communication. Developers can access the current IO states via HTTP requests, AJAX, or JavaScript to integrate the device into other websites or applications. The Box-to-Box feature enables switching signals to be forwarded 1:1 over the network, facilitating location-independent control. These connectivity options make the device ideal for network control in connected environments.

Flexible Alarm and Notification Functions

The Web-IO 4.0 Digital offers extensive alarm and status notification capabilities. Up to 30 actions can be configured to be triggered automatically when changes occur to the inputs or outputs. These include email notifications, SNMP alarms (SNMP traps V1, V2, V3), switching of its own outputs, controlling outputs of another Web-IO, or sending HTTP requests to control third-party devices. These functions are especially beneficial in critical applications such as remote monitoring or fault signal detection, where rapid responses to events are required. The ability to send status notifications via email supports the documentation and analysis of switching operations, 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 for the requirements of Industry 4.0 and the Internet of Things. It supports modern protocols such as OPC UA, REST, and MQTT, which enable easy integration into automation systems and IoT platforms. AMQP is also supported upon request. Other interfaces, including SNMP V1, V2c, V3, Modbus TCP, OPC DA, Syslog, and Sensobase (database integration via ODBC), enable connectivity to existing systems and databases. Developers can access IO states directly via TCP and UDP sockets (client and server) to develop custom solutions. The support for FTP allows for the logging of switching signals, improving the traceability of processes. These connectivity options make the device a future-proof solution for building automation, home automation, and industrial applications.

Data Storage and Time Management

The Web-IO 4.0 Digital features an integrated data logger that stores switching operations and state changes. The storage duration ranges from at least 7 weeks to a maximum of 20 years, depending on the selected storage frequency (15 seconds to 1 hour). The data can be exported in various formats, such as FTP, Excel files, or email attachments, making further processing easier. An internal battery-buffered clock ensures precise timestamps, which are optimized by synchronization with a time server. These features ensure reliable documentation and analysis of switching operations, which is particularly beneficial in process monitoring and machine data acquisition.

Versatile Applications

The Web-IO 4.0 Digital, 12x In, 12x Out is designed for a wide range of applications. In remote monitoring and fault signal detection, it monitors switching inputs and reports state changes to detect and resolve operational disruptions. In building automation, it controls devices such as lighting, gates, or barriers and allows location-independent switching operations. In home automation, it supports the automation of lighting or heating systems to enhance comfort and energy efficiency. In industrial environments, the device is suitable for process monitoring and visualization, as well as machine data acquisition (MDA), to optimize production processes. The pulse counters on the inputs enable the recording of events such as production cycles or flow rates. Additional applications include the control of barriers or access systems.

Flexible Power Supply and Compliance with Standards

The power supply for the Web-IO 4.0 Digital is provided via an external supply (12–24 V DC) through a screw terminal connection. This flexibility enables use in various environments. The device is compliant with standards for office and industrial environments and offers high immunity to interference according to EN 61000-6-2, as well as low electromagnetic emissions according to EN 55032:2015 + A1 Class B, EN 61000-3-2, and EN 61000-3-3. These features ensure reliable and interference-free operation, even in demanding environments.

Please note: The power supply is NOT included in the 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 the option for DIN rail mounting make it ideal for use in industrial environments. The internal clock, buffered by a battery, ensures precise time measurement, which is optimized by synchronization with a time server. These features highlight the device's durability and reliability, even under demanding conditions.
