RTU870 Data Sheet - Brodersen Controls - #1

RTU870

The RTU870 unit is a compact outstation with 24 inputs/outputs and serial port options designed for use in the industrial environment.

The unit is designed in a very compact 216 mm wide module for DIN-rail mounting (35 mm symmetrical). Dimensions conform to DIN 43880 (used for circuit breakers) thus insuring easy installation in standard installation panels and boxes widely available in the electrical industry.

The RTU870 are delivered with a range of different power supply options including charger options (with a battery monitor) for an external lead acid battery, enabling the RTU to operate regardless of interruptions in the mains supply.

The RTU870 has a number of integral inputs and outputs and further I/O's can optionally be added via an expansion bus.

The RTU870 support optional meter interface IEC1107 ModeC and IEC870-5-102 on the serial interface. The physical interface is both V24 RS232 and Currrent Loop. Both meter protocols are partly transparent tranfered via the IEC870-5-101.

The main communication is done through the EN/IEC60870-5-101 protocol. Communication interface is V.23 or RS232. Additional COMs options is to be added. The RTU870 do in general support modem dial-up features.

The unit can be programmed to perform simple control sequences using an EN/IEC1131-3 IL (PLC) programming language. All varibles connecting I/O, serial interfaces and IEC-870-5-101 mappings are programmed also using the EN/IEC61131-3 programming. Program­ming and setup is achieved by using a standard PC connected to the programmer port, with the IOTOOL870 software package installed.

The ModbusRTU protocol is used in the programming port.
