The devices of the RTU3000C series are compact telecontrol stations (RTU: Remote Terminal Unit) for applications with their own power supply. They are particularly well suited for monitoring and control of remote stations that are not connected to a power supply network and can collect data of connected sensors with time stamp independently, preprocess the data, and transfer it to a control center. The RTU3000C is supplied with power by a battery, an accumulator or a solar panel or by a 12 … 24 V DC power supply unit.

The devices of the RTU3000C series are characterized by the following properties:

• Worldwide data exchange between a remote measuring point and a control center via public or private networks (WAN), e.g. mobile radio networks, Internet.
• Communication with a control center (telecontrol center) with the help of the DNP3, IEC 60870-5-104 or SINAUT ST7 telecontrol protocols
• Connection to a control center with TeleControl Server Basic
• Acquisition of process signals, alarms, count pulses, measured values or output of switching commands by means of integrated inputs as well as digital inputs and outputs
• Pre-processing of the acquired signals by the RTU with 38 different function blocks
• FTP client functionality for transmitting data to an FTP server
• Time synchronization
  • on the basis of NTP (Network Time Protocol)
  • by means of the partner in the control center
• Automatic alarm transmission per email or text message
• Use as data logger by saving the process values to SD card
• Data buffering in the substations in the event of connection failures
• LED signaling for fast diagnostics
• Compact industrial enclosure in S7-1200 design for mounting on a standard DIN rail
• Use in harsh environment thanks to extended temperature range from -40 to +70 °C and IP68 protection thanks to optional protective enclosure
• Fast commissioning thanks to easy configuration using the integrated web server

Additionally for RTU3030C:

• Integrated UMTS modem for global wireless data exchange between a remote measuring point and a control center based on the mobile radio standard UMTS (Universal Mobile TelecommunicationsSystem) with data transmission rates of up to 42 Mbps in the downlink (HSDPA) and 5.76 Mbps in the uplink (HSUPA)
• UMTS operation with fixed or dynamic IP addresses, depending on telecommunication contract
• Time synchronization over the mobile radio network:
• Wake-up of station from sleep mode by means of text message or call
