Precise Control and Monitoring with the Web-IO 4.0 Digital, 2x In, 2x Out from Wiesemann & Theis

In modern industrial and building automation, the control and monitoring of switching signals are crucial for process optimization and operational safety. The Web-IO 4.0 Digital, 2x In, 2x Out from Wiesemann & Theis is a network-enabled device that controls and monitors two digital switching inputs and two digital switching outputs via TCP/IP Ethernet. 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, application possibilities, and benefits of this versatile device developed for remote monitoring, building automation, and home automation.

Precise Control and Monitoring of Switching Signals

The Web-IO 4.0 Digital, 2x In, 2x Out features two 24V digital switching inputs with integrated 32-bit pulse counters to precisely detect events such as switching actions or pulses. The two switching outputs are 24V digital outputs capable of sourcing current up to 500 mA and are short-circuit proof. Voltages of 12 V, 48 V, 110 V, or 230 V can be switched via coupling relays. 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 combination of inputs with pulse counters and robust outputs makes the device ideal for process monitoring, machine data acquisition (MDA), and fault message detection.

Intuitive Operation and Network Connectivity

The Web-IO 4.0 Digital is very user-friendly thanks to an intuitive web interface, switchable between German and English. Users can control the switching outputs directly via the web interface and monitor the status of the switching inputs in real time. The interface is optimized for smartphones, allowing control on the go. Support for HTTP and HTTPS ensures secure communication. Developers can access current IO states via HTTP requests, AJAX, or JavaScript to integrate the device into other websites or applications. The box-to-box function allows switching signals to be forwarded 1:1 over the network, facilitating cross-location 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 comprehensive alarm and status notification options. Up to 30 actions can be configured, triggered automatically by changes at the inputs or outputs. These include email notifications, SNMP alarms (SNMP traps V1, V2, V3), switching of own outputs, controlling outputs of another Web-IO, or HTTP requests to control third-party devices. These functions are particularly beneficial in critical applications such as remote monitoring or fault message detection, where quick responses to events are essential. The ability to send status messages via email supports documentation and analysis of switching events, which is crucial for audits and quality management.

Seamless Integration into Industry 4.0 and IoT

The Web-IO 4.0 Digital is perfectly equipped for the demands of Industry 4.0 and the Internet of Things. It supports modern protocols such as OPC UA, REST, and MQTT for easy integration into automation systems and IoT platforms. AMQP is also supported on request. Additional interfaces such as SNMP V1, V2c, V3, Modbus TCP, OPC DA, Syslog, and Sensobase (database integration via ODBC) enable connection to existing systems and databases. Developers can access IO states directly via TCP and UDP sockets (client and server) to develop custom solutions. FTP support allows logging of switching signals, increasing process traceability. These connectivity options make the device a future-proof solution for building automation, home automation, and industrial applications.

Data Logging and Time Management

The Web-IO 4.0 Digital includes an integrated data logger that records switching operations and status changes. Storage capacity ranges from at least 7 weeks to a maximum of 20 years, depending on the selected logging frequency (15 seconds to 1 hour). Data can be exported in formats such as FTP, Excel files, or email attachments, facilitating further processing. An internal battery-buffered clock ensures accurate timestamps, optimized through synchronization with a time server. These functions ensure reliable documentation and analysis of switching operations, which is especially beneficial in process monitoring and machine data acquisition.

Versatile Application Areas

The Web-IO 4.0 Digital, 2x In, 2x Out is designed for a wide range of applications. In remote monitoring and fault message detection, it monitors switching inputs to detect and report operational faults. In building automation, it controls devices such as lighting, gates, or barriers and enables cross-location switching operations. In home automation, it supports automation of lighting or heating systems to increase 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 allow detection of events such as production cycles or flow rates. Other application areas include control of barriers or access systems.

Flexible Power Supply and Standards Compliance

The Web-IO 4.0 Digital is powered either via Power-over-Ethernet (PoE) with phantom power via data pairs or spare wire pairs, or via an external power supply (12–48 V DC) through a screw terminal. This flexibility enables use in environments with or without PoE infrastructure. The device complies with standards for office and industrial environments and offers high immunity according to EN 61000-6-2 and low 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: A 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 DIN rail mounting capability make it ideal for use in industrial environments. The internal clock, buffered by a battery, ensures precise timekeeping, optimized through synchronization with a time server. These features highlight the durability and reliability of the device, even under demanding conditions.
