SCADA or control center software via IEC 60870, DNP3 and MODBUS TCP protocols. With its easy, flexible and fast programming capabilities and expandable I/O capability up to 1024 points, Mikrodev RTU products are preferred for electrical applications. Mikrodev RTU300 Series RTUs are programmed mainly using Function Block Diagram - FBD language which is defined in IEC 61131-3 standard.
✓ Make sure that the environment in which your device is being used is free of moisture, electric shock, vibration and dust. ✓ Pay attention to the supply voltage and the connections of the product. Mikrodev is not responsible for any issues due to power failure since there is no auxiliary supply (UPS) on the device.
Mounting Information DIN Rail Mounting First, the upper part of the device is mounted on the DIN rail. Then, with the help of the springs behind the device, when a lightly force is applied to the lower part, the device locates into the DIN rail easily and the montage is completed (See Figure 1).
