Description

The Wittelb WIN-IO-8DDME-IO Module is a dedicated industrial remote I/O unit designed for distributed control systems. It bridges the gap between physical sensors/actuators and networked management software by converting digital signals into Modbus TCP packets transmitted over standard Ethernet. Its robust relay outputs can directly switch significant loads, while the wide-range digital inputs accept signals from various industrial sensors and switches.

Engineered for 24/7 operation in industrial environments, the module supports a wide 12-24V DC or 24V AC/DC power input range and operates reliably within a 0–60°C temperature range. The integrated web server provides a straightforward tool for assigning IP addresses, configuring I/O behavior, and monitoring real-time status, making it an ideal building block for Industry 4.0, building automation, and machine monitoring applications.

Key Features

Eight optically isolated digital inputs compatible with 3.3V to 30V DC sensor signals.
Eight electromechanical relay outputs rated for 10A at 240V AC or 28V DC for direct load control.
Standard Modbus TCP protocol support over 10/100 Mbps Ethernet for seamless PLC and SCADA integration.
Integrated reverse polarity protection and resettable fuses safeguard the module from wiring errors.
DIN-rail mountable form factor with per-channel LED indicators for compact, organized panel installation.
Built-in web configuration interface for easy network setup and I/O parameter management without dedicated software.
Wide-range power supply acceptance (12-24V DC / 24V AC/DC) for flexible integration into existing control panels.
Designed for continuous operation in industrial environments with an operating temperature of 0 to 60°C.

Applications

Industrial Automation & Machine Control: Remote monitoring and control of motors, valves, and sensors in manufacturing lines.
Building Management Systems (BMS): Centralized control of lighting, HVAC, and security systems via Ethernet.
Process Monitoring & Telemetry: Data acquisition from level sensors, flow meters, and pressure switches for SCADA systems.
Smart Agriculture & Environmental Control: Automating irrigation pumps, ventilation fans, and greenhouse climate systems.

Frequently Asked Questions

How do I configure the IP address and Modbus parameters for this I/O module?

Connect the module to your network via Ethernet and power it on. Use a network scanner to find its default IP or set your computer to the same subnet. Then, access the module's built-in web interface by entering its IP into a browser. From there, configure the static/DHCP IP, subnet mask, gateway, and Modbus TCP unit ID as required for your SCADA or PLC system.

What is the maximum switching current and voltage for the relay outputs?

Each of the eight relay outputs is rated for a maximum of 10 Amps at 240 Volts AC or 28 Volts DC. This rating is suitable for directly controlling motors, solenoids, contactors, or lighting circuits. Ensure the total inrush current of inductive loads does not exceed the relay's specification to guarantee longevity and safe operation.

Can the digital inputs accept signals from 24V PLC systems or proximity sensors?

Yes, the eight digital inputs are designed for a wide voltage range of 3.3V to 30V DC, making them fully compatible with standard 24V industrial PLC outputs and PNP/NPN proximity sensors. The inputs are optically isolated, protecting the module's logic from voltage spikes or ground loop issues commonly found in industrial environments.

What power supply is required, and how is the module typically installed?

The module requires a 12-24V DC or 24V AC/DC power source, commonly available in control panels. For installation, mount it on a standard 35mm DIN rail inside an enclosure. Connect power, Ethernet, and your field devices (sensors to inputs, loads to relay outputs) following the terminal block labeling. The web interface then allows for final configuration and testing.
