Talgil - RTU RF G5 - MOD BUS LIN Expansion

The LIN Expansion series extends the capabilities of the Talgil Modular RTU and DREAM2 controller, offering flexible I/O options to meet a wide range of field application needs.

Compatible with RTU RF G5 (in G5 FAST mode) and DREAM2 Controllers, LIN cards connect via the dedicated LIN Port and support both parallel connection and automatic detection by the Master unit.

Each LIN card must be assigned a unique address when multiple cards of the same type are used. The Modular RTU auto-detects the card type and address, seamlessly integrating the data into the system.

Power Requirements:

When using a LIN Expansion with the Modular RTU, a 12V DC power supply is required. Connect the rechargeable battery to the BATTERY input on the power supply plug. Charging is supported via an 18V DC source (solar panel or power supply) connected to the CHARGE input.

Available LIN Expansion Models

At this stage - the following LIN Expansion Models are available:

• 4 ANA LIN (4 ANALOG INPUTS)
• 840 LIN (8 OUTPUTS / 4 DIGITAL INPUTS / 0 ANALOG INPUTS)
• MODBUS LIN
• SDI LIN

In G5 Fast, there is an option to connect several LIN cards in parallel. When connecting several LIN cards of the same type to the RTU Modular, set up a unique address for every LIN card. The RTU Modular automatically detects the LIN card type, and LIN card address, and transmits the LIN card type, address, and the LIN card Data to the Master unit.

MODBUS LIN Expansion Module: Available Soon!

The MODBUS LIN Expansion allows integration between the Talgil system and third-party Modbus RTU devices, such as pumps, VSDs, valves, and sensors. This unit connects via the LIN port to any G5 Modular RTU (FAST MODE) or directly to the DREAM2 Controller (via RS485 Bridge).

• Supported Modbus Functions

The LIN Expansion enables both control and monitoring through four Modbus function types:

• Write Coils (Displayed as Satellites in DR2)
  • Example: Start/stop pumps, open/close valves, activate filters or injectors
• Read Discrete Inputs (Displayed as Contacts in DR2)
  • Example: Monitor pump status, float switches, digital pressure sensors
• Read Holding/Input Registers (Displayed as Analog Inputs / Contacts in DR2)
  • Example: Read flow rate, pressure, temperature
• Write Holding Registers (Displayed as Analog Outputs in DR2)
  • Example: Send setpoints (e.g., target pressure) to Modbus devices
• Capacity:
  • ⁠ ⁠64 Digital Outputs (Coils)
  • ⁠ ⁠⁠64 Digital Inputs (Discrete Inputs)
  • ⁠ ⁠⁠64 Analog Inputs (Registers)
  • ⁠ ⁠⁠64 Analog Outputs (Writable Registers)
• Programming Tool:
  • Modeler Software: This software creates a Modbus RTU model. The model includes a list of register types, register addresses, units, hysteresis, and description.
  • MBI Configurator: Loads the saved configuration into the DREAM2 Controller (via config file)
• Control and monitoring up to four modbus RTUs
