      This node receives digital input signals from the SmartLink Universal IO digital input card.
    </p>
  
    <p>
      You must configure the following:
    </p>
    <ul>
      <li><strong>Gateway Node:</strong> Reference to the gateway connected to the bus.</li>
      <li><strong>Device Address:</strong> Address of the I/O module.</li>
    </ul>
  
    <p>
      The node emits a message with the analog value and channel info.

      <code>
        {
          value: true,
          channel: 0,
        }
      </code>
    </p>
  
    <ul>
      <li><strong>value:</strong> received digital input signal (boolean true or false)</li>
      <li><strong>channel:</strong> digital intput channel index (0 to 3)</li>
    </ul>
     
    <p>
      This node assumes the hardware module is properly wired and supports digital input.
    </p>
