Description

The Wittelb WIN-IO-4DDAME-MQTT-IO Module is a hardened industrial-grade I/O node engineered for distributed control and IoT telemetry. It consolidates discrete digital I/O and high-resolution analog sensing into a single, network-addressable unit, eliminating the need for multiple remote terminal units. Its core architecture is built around a robust Ethernet controller that manages concurrent Modbus TCP and MQTT protocol stacks, allowing seamless bridging between traditional industrial automation networks and modern cloud-based IoT systems.

Power management is optimized for 24VDC industrial standard supplies, with a wide 12-24VDC operating range and low operating current, making it suitable for both panel-mounted and energy-conscious applications. The module’s fast scan and response time ensure minimal latency for real-time control loops. Its compact, DIN-rail mountable enclosure is designed for harsh environments, operating reliably within a 0–60°C temperature range, making it an ideal drop-in solution for factory automation, building management, and remote equipment monitoring.

Key Features

  • Multi-protocol Industrial Gateway: Simultaneously supports Modbus TCP for PLC integration and MQTT 3.1.1/5.0 for cloud IoT messaging, acting as a protocol converter.
  • High-Density I/O Interface: Provides 12 configurable channels (4x DI, 4x DO, 4x AI) for connecting sensors, switches, relays, and analog transducers in a single compact unit.
  • Precision Analog Acquisition: 12-bit resolution analog inputs deliver accurate voltage/current measurement for process variables like temperature, pressure, and level.
  • Industrial Network Security: Implements TLS/SSL encryption for MQTT connections, securing telemetry data against interception in untrusted networks.
  • Rapid Response & Real-Time Operation: Features a typical 2ms I/O update time (max 6ms) for time-sensitive control applications and fast event logging.
  • Robust Mechanical Design: DIN-rail mounting, wide operating temperature range (0–60°C), and 12-24VDC input ensure reliability in industrial control panels.
  • Low Power Profile: Consumes only 120mA @ 12V, enabling deployment in locations with limited power budgets or on backup power systems.

Applications

  • Industrial Automation & Machine Monitoring: Remote I/O for PLCs to read sensor states and control actuators via Modbus TCP.
  • Building Management Systems (BMS): Monitoring room occupancy (DI), controlling lighting/ventilation (DO), and reading temperature/humidity sensors (AI).
  • Smart Agriculture & Environmental Monitoring: Collecting data from soil moisture sensors (AI) and controlling irrigation valves (DO) over MQTT.
  • Energy Management & Submetering: Integrating with power meters (Modbus) and publishing consumption data to cloud dashboards via MQTT.
  • Predictive Maintenance & IIoT: Connecting legacy equipment to IoT platforms for real-time operational data analytics and alerting.

Frequently Asked Questions

How do I configure the WIN-IO module for Modbus TCP communication?

Connect the module to your network via Ethernet. Use configuration software (often provided via web interface or utility) to set a static IP or DHCP. Assign a Modbus slave ID and map the digital inputs/outputs and analog inputs to specific holding/input registers as defined in the product datasheet for integration with your PLC or SCADA master.

What is the procedure to set up MQTT publishing for the analog inputs?

Access the module's configuration page to enter your MQTT broker IP, port, and credentials. Define publish topics for each analog input channel. Configure the data format (e.g., JSON, raw value) and publishing interval. Enable TLS if required. The module will then transmit the 12-bit analog readings as telemetry messages to the specified broker at the set frequency.

What power supply is required, and how is the wiring connected?

Provide a stable 12-24VDC power source connected to the designated terminal block. Ensure correct polarity. The digital inputs typically accept a wet contact (24V) or dry contact signal. Digital outputs are often relay or transistor-based—check specs for load ratings. Analog inputs are usually configured for 0-10V or 4-20mA via jumpers or software settings.

Can I use both Modbus TCP and MQTT protocols simultaneously?

Yes, the module operates both protocol stacks concurrently. You can have a Modbus master polling for real-time control while the same I/O data is published asynchronously to an MQTT broker for cloud dashboards and historical logging, making it a versatile gateway between OT and IT systems.
