Efficient time control with the Web-IO Time Switch Digital 4xOut from Wiesemann & Theis
In modern industrial and building technology systems, time-based control of switching signals plays a central role. It is crucial for automating processes, improving energy efficiency, and optimizing workflows. The Web-IO Time Switch Digital 4xOut from Wiesemann & Theis is a powerful, network-enabled device with four flexibly configurable switching channels. It offers the ability to set and execute switching times centrally via calendar files in iCal format (*.ics) or online calendar services such as Google Calendar and Apple iCloud.
With its user-friendly web interface, extensive network options, and robust hardware architecture, this device is well-prepared for the demands of Industry 4.0 and modern IoT solutions. It is suitable for use in home and building automation and ideal for remote monitoring tasks and time-controlled process management.
Four flexible switching channels with time programming
The Web-IO Time Switch Digital 4xOut features four digital channels using 24V technology, each configurable as an input or output. Each output supports switching currents up to 500 mA and is suitable for controlling devices such as lighting, motors, barriers, or valve controls. The bistable switching logic ensures reliable operation with minimal energy consumption.
Channels can be operated according to preset schedules from calendar files. These files can be uploaded via the web interface or automatically synchronized from linked online calendars. Users can create and manage complex switching sequences centrally without having to program each control individually.
Versatile input and monitoring functions
Configured as inputs, the channels monitor digital signals using an integrated 32-bit pulse counter, which precisely detects events such as switching operations or pulse sequences. Status changes can be displayed and logged in real time via email, FTP upload, or directly in the web interface. This opens up applications in fault reporting and remote plant monitoring.
User-friendly web interface and network integration
The modern web interface is bilingual (German/English) and optimized for smartphones, allowing switching operations to be checked or settings adjusted while on the go. Control is via a secure connection using HTTP or HTTPS. Developers can also access channel data directly using HTTP requests, AJAX, or JavaScript to integrate into custom applications or automation platforms.
Easy integration into local and cloud-based systems makes the Web-IO Time Switch Digital 4xOut a flexible solution for a wide range of use cases – from automated lighting control to production line monitoring.
Comprehensive alarm and event logging
Up to 30 actions can be defined to automatically execute when status changes occur or scheduled switching takes place. Possible actions include:
- Email notifications as alarms or status reports
- HTTP requests to control external IoT devices or cloud applications
- FTP uploads to document and analyze events
- Direct control of other Web-IO devices over the network
These features are especially useful in critical environments where rapid, precise responses to events are required. Continuous logging of all switching operations supports audits and quality management processes.
Calendar integration for centralized control
One of the most notable features is integration with calendar services. Scheduling can be based on classic iCal format (*.ics) files or synchronized with Google Calendar and Apple iCloud. This allows switch times to be maintained directly from common organizational tools without labor-intensive manual configuration on the device.
Precise time management
The device is equipped with an internal battery-backed real-time clock, enabling accurate timestamps and reliable execution of switching schedules. Synchronization via a time server ensures all schedules run precisely as planned. This is essential for applications such as lighting control, barrier operation, or production processes where exact switch times are required.
Application areas in practice and industry
- Building automation: time-controlled operation of lighting systems, doors, and climate control.
- Home automation: automation of everyday routines such as lighting or heating schedules.
- Remote monitoring: time-based alarms and status updates.
- Industrial automation: centralized scheduling of production processes or machine operations.
Stable power supply and compliance
Power is supplied via 12–24V DC using screw terminals, making it suitable for use in many industrial and building technology installations. The device meets standards such as EN 61000-6-2 and EN 55032:2015 + A1, ensuring high immunity to interference and low emissions for reliable operation.
Durability and continuous operation
The Web-IO Time Switch Digital 4xOut is designed for long-term use and, with robust construction and DIN rail mounting, can be securely installed in control cabinets. The five-year manufacturer’s warranty demonstrates the high quality and reliability of the hardware.
Time-controlled switching for networked systems
The Wiesemann & Theis Web-IO Time Switch Digital 4xOut combines precise time control, flexible channel configuration, and extensive network protocol support in a compact, high-performance device. With calendar integration, secure web control, and flexible alarm functionality, it is an indispensable tool for modern building automation, home automation, and industrial time control systems.
