🎯 Purpose:

RIO-mini DI4DO4 is a compact microprocessor-based module that combines digital inputs and outputs for:

  • 📊 collecting data from digital sensors;
  • ⚙️ controlling external actuators;
  • 🌐 integration into automation systems via RS-485 / Modbus RTU.

The module can be used as an element of an automated control system (ACS TP), as part of accounting and process control systems, or as a standalone device.

🔧 Functional Capabilities:

4️⃣ Digital inputs:

  • support for PNP/NPN-type signals, “dry contact”;

🧮 Built-in simple counters (4 channels):

  • counting pulses from sensors (PNP/NPN, encoders, level sensors, etc.);
  • measurement of parameters:
    • 📦 product quantity,
    • 📏 length,
    • ⚖️ weight,
    • 🛢 volume,
    • 🚗 distance/path;
  • functions ⏸ stop or 🔄 reset when the threshold value is reached.

4️⃣ Digital outputs:

  • intended for controlling actuators, alarms, relays, etc.;
  • output elements — transistor switches, mechanical relays, or solid-state relays (depending on the modification).

🖥 Communication Interfaces:

  • 🔗 RS-485 with Modbus RTU support — for integration with PLCs, panel controllers, SCADA, PCs;
  • 💻 USB port — for local connection and parameter configuration.
