The RTU3030C is a compact telecontrol station (RTU: Remote Terminal Unit) for applications with their own power supply. It is particularly suited for the monitoring and control of remote stations that are not connected to an energy supply network; it can collect data of connected sensors with time stamp independently, preprocess the data, and transfer it to a control center by means of mobile radio. The RTU3030C is supplied with energy by a battery, an accumulator or solar panel or a 12 … 24 V DC power supply unit.

The RTU3030C is characterized by the following properties:

• Global, wireless data exchange between a remote measuring point and a control center based on the mobile telecommunication standard UMTS (Universal Mobile Telecommunications System) with data transmission speeds 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 mobile telecommunication contract
• Communication with a telecontrol center with the help of the standard protocols DNP3 or IEC 60870-5-104
• Connection to Telecontrol Server Basic as of V3.0+SP2
• 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
• Time synchronization
  • on the basis of NTP (Network Time Protocol)
  • by means of the partner in the control room
  • by means of the mobile radio network
• Automatic sending of alarm emails or alarm text messages
• Wake-up station from sleep mode by means of text message or call
• 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 mounting rail
• Use in tough environment due to extended temperature range from -40 to +70 °C and IP68 protection due to external protective enclosure
• Fast commissioning thanks to easy configuration using the integrated web server

In conjunction with the "TeleControl Server Basic" control room software, the RTU3030C forms a telecontrol system with additional properties:

• Connection of up to 5000 telecontrol stations to the control center via OPC UA
• Central status monitoring of the substations
• No special provider services required for fixed IP addresses
• Teleservice access to the substations via mobile radio
• Wake-up of substations by calling or text message
