RTU300 SERIES –HARDWARE MANUAL
Preface
Mikrodev RTU300 series RTUs can monitor and control Intelligent Electrical Devices
(protection relays, reclosing cutters, energy and quality analyzers ... etc) via industry
standard protocols like IEC 61850, Modbus TCP and Modbus RTU. Thay can also
communicate with 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. Thanks to programming
with FBD language, you can develop applications easily and quickly with drag and drop
logic.

WARNING!
✓Please take care of the following issues when using Mikrodev devices.
✓Since the unit operates with 24 VDC (12-36 VDC) voltage, you should take care of
the voltage level that the unit is connected to. If a voltage above this voltage level
is applied, the device may be damaged and may be out of warranty.
✓Make sure that the energy connection of your device is connected to the ground or
to a properly grounded terminal.
✓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.
✓The fuse to be used must be a FF super fast type and current limit value 1A.
✓Do not use the device under conditions other than the environmental conditions
specified in the "Electrical Specifications" section (humidity, dust, liquid and
temperature, etc.)
✓Removing the warranty label on the product or removing the protective case will void
the warranty.
✓Products that are damaged, boxes have been changed and other brand labels are
affixed are not covered by the warranty.
✓The appliance must not be cleaned with solvents (thinner, benzine, acid etc.) or with
abrasive cleaning agents.
✓Only dry cloth should be used when cleaning the appliance.
✓Do not open the device by removing the case of the appliance, do not interfere with
the electronic components and circuits. There is no user-replaceable part inside the
device.
✓If there is a problem or malfunction on your device, it should only be repaired by
an authorized service. Installation and electrical connections must be made by
technical personnel in accordance with the instructions in the operating manual.
Failure to comply with these rules may result in death, serious injury or property
damage

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).
Figure 1 DIN Rail Mounting
Expansion Installation
Assembly between RTU300 series RTU products and XIO211 series expansion modules is
carried out by sliding the tabs over the rail so that the tabs overlap each other
