Description

The Wittelb WIN-IO-4AIM is a dedicated industrial signal converter designed to bridge the gap between legacy analog sensors and modern digital control networks. It accepts inputs from four independent channels, supporting standard industrial signals like 4-20mA current loops and 0-10V voltage levels, and converts them into precise digital values transmitted via the Modbus RTU protocol over an RS485 bus.

Engineered for reliability in harsh environments, the module operates on a 12-24VDC supply and features a durable casing rated for 0-60°C. Its integrated RS485 transceiver enables robust, noise-immune communication over distances up to 700 meters without repeaters, making it suitable for expansive industrial plants, water treatment facilities, and energy monitoring applications. The internal DIP switch allows field technicians to quickly set the module’s unique slave address and communication baud rate, streamlining deployment and maintenance.

Key Features

  • Four-channel analog input converter for industrial current (4-20mA) and voltage (0-10V) signals.
  • High-noise immunity RS485 communication supporting the Modbus RTU protocol for PLC and SCADA integration.
  • Configurable network parameters (Slave ID, Baud Rate) via an internal DIP switch for flexible setup.
  • Integrated resettable fuses provide reverse polarity protection for both power and communication ports, enhancing system durability.
  • Low power design consuming approximately 110mA, suitable for 12-24VDC industrial power supplies.
  • Compact, DIN-rail mountable form factor with LED status indicators for easy installation and visual diagnostics.
  • Wide operating temperature range (0°C to 60°C) for reliable performance in industrial control panels.

Applications

  • Industrial process control and monitoring of analog sensors (pressure, temperature, flow).
  • Building Automation Systems (BAS) for HVAC and energy management data acquisition.
  • Remote telemetry and SCADA system integration in water/wastewater treatment plants.
  • Factory automation for connecting legacy analog instrumentation to modern PLC networks.
  • Environmental monitoring stations requiring long-distance signal transmission.

Frequently Asked Questions

How do I configure the Slave ID and baud rate on the WIN-IO-4AIM converter?

Open the module's enclosure to access the internal DIP switch bank. Refer to the product datasheet for the switch coding table. Set the switches for your desired unique Modbus slave address (1-247) and communication baud rate (common rates are 9600, 19200, 38400, 57600). Ensure power is disconnected before configuration and secure the enclosure after setting.

What types of analog signals can the 4 input channels accept?

Each of the four channels is configurable via wiring and potentially software to accept standard industrial signals: 4-20 mA current loop (2-wire transmitter), 0-20 mA, or 0-10 VDC voltage input. Ensure your sensor output matches one of these ranges and wire it to the correct terminal block pins, observing the specified common ground or supply requirements.

What is the maximum communication distance, and what factors can affect it?

The module supports RS485 communication up to 700 meters without repeaters under ideal conditions. Actual range can be reduced by lower signal strength from the Modbus master, electromagnetic interference, cable quality (use twisted pair shielded cable), and improper termination. Ensure the RS485 bus is correctly terminated with a 120-ohm resistor at each end of the line for optimal performance.

How do I wire the power supply and what protections are in place?

Connect a 12-24 VDC power source to the designated two-pin 5.08mm terminal block, observing correct polarity. The module incorporates resettable fuses that protect both the power and communication ports from damage due to accidental reverse polarity connections. Always use a stable, industrial-grade DC power supply within the specified voltage range.
