Take a quick overview

Communicates Real-Time and Seamlessly
eRTU-X100 is a Remote Terminal Unit/Protocol Gateway device that provides data transmission between the field and the central station. It is the main device used for communication in medium high voltage automation. It provides transmission by talking to control centers and breakers at the same time. It also processes data with precise time stamp. It already supports all protocols used in energy automation applications on this device. Counter, protection relay, analyzer etc. in the field. It communicates with different devices over different protocols at the same time, and ensures that the collected data is converted into protocols related to the center or other units and transmitted. The device has been designed to provide all industrial compatibility required by this field.

eRTU-X100 reads data from the meters in the field with serial or ethernet protocols. Simultaneous communication can be achieved with different brands of meters on the same line over different protocols (for example, Modbus and DLMS).
It is designed in a modular structure and can provide different types of communication in the field at once. Thus, application-specific hardware cost is optimized. It uses EtherCAT protocol in terms of speed, security and uninterrupted communication in its internal communication with its additional modules.

  • Modular design
  • Media conversion
  • Redundancy

Protocol gateway

Convert any protocol/s, one-to-one or multiple-tomultiple simultaneously. eRTU-X100 is gateway to/from any protocol from/to EtherCAT:
Slave to supply critical data to the upper layer of the system
Master in order to control and monitor time-critical applications integrated into the whole system

Sequence of events

Historical records with precise timestamps can be saved on non-volatile memory to allow analysis of critical events later.

Modular Design

There are 2 slots on the main board to integrate 3 different on-board module options:
• 12 digital inputs
• 2 analog input, 6 digital inputs, 4 digital outputs
• Wide-range power supply
• Battery back-up
External analog/digital I/O and current/voltage measurement modules can be controlled in real-time from EtherCAT bus:
• eXIO-D100
• eXIO-M100
• eCVM-P100

Media Conversion

Communication media between different stages of applications can be converted efficiently, one-to-one or multiple-tomultiple simultaneously.


HSR/PRP can be applied from configured F/O and copper ethernet ports to supply zero recovery time on networks faults.
Hardware level RSTP can also be available to provide recovery on regular ring networks.
