The DinBox RTU SL is a complete GPRS SCADA communication device in a DIN-rail housing and is conceived to operate via several communication protocol environments (IEC 60870-5-104, NMKD-3085 ASCII). The product is a unique IEC 60870-5-104/Modbus mapping device for monitoring, alarming & controlling. Registration and storage of measured values and sample rates are made possible by the integrated memory card.

    No internal fuse 
  • Interfaces & Connectors
    One serial RS-232 interface (RJ-45) which can be connected to a computer or similar device via a RJ-45 to DB-9 serial cable. Only RxD, TxD, RTS and CTS are used. If RTS is active the LED RTS will illuminate.
    One isolated 2-wire RS-485 interface. This interface can be used to communicate with intelligent periferials. JP4 can be used to terminate the line with a 120E resistor.
  • Configuration interface: 
    All local communication with the DinBox RTU SL6087 for configuration, setup and the necessary maintenance tasks is done via the serial “configuration interface”.
    A terminal software program (eg. HyperTerminal) must be used to communicate with the RTU. The following parameters must be used :
    Speed : 38.400 bps
    Data bits : 8
    Parity : none
    Stop bits : 1
    Flow control : none
  • I/O:
    8 x DI galvanically isolated (opto coupler) active inputs (24Vdc)
    8 active inputs thanks to an internal 24Vdc dc/dc convertor. To minimise contacts, one common contact is used.
    opto coupler SFH6156-1
    active voltage : 24 Vdc
    Conductor cross section: rigid min. 0.08 mm2 flexible min. 0.08 mm2 / rigid max. 1.50 mm2 flexible max. 1.50 mm2
    2 x AI not galvanically isolated (- connection = GND)

    The DinBox RTU SL6087 can monitor up to 2 non isolated analogue signals
    12 bit single ended ADC’s (ATXMEGA256D3)

    Atmel ATXMEGA256D3 processor: All functionalities are automatically guided by the Atmel processor with the proper firmware. This processor will/can control the following tasks:
    - communication with the RTC (real time clock)
    - communication with the Sierra Wireless (Wavecom) SL6087 GSM/GPRS module
    - serial RS-485 communication
    - read AD converters to measure AI voltages
    - calculations on measured or received data

    - set DO's
    - write and read data in/from the non volatile FRAM memory
    - write and read data in/from the MMC/SD memory
    MMC/SD: MMC/SD card socket. This memory can be used to store the firmware code, configuration, measured data and log information. Status LED 'SD' will illuminate when a proper MMC/SD card is installed.
    FRAM: 2 FRAM (ferro electric RAM) of 64 Kb (8.192 x 8 bits). Used to store the configuration, measured data and log information.
    RTC: Built-in 10 ppm real time clock with a separate battery backup.
