Compact outstation with data logging and local control
RTU8
Typical RTU8 application
INTRODUCTION
The RTU8 unit is a compact outstation with data logging facilities
designed for use in the industrial environment.
The unit is designed in a very compact 108/162 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 RTU8 can be delivered with a built-in mains power supply and a
charger (with a battery monitor) for an external lead acid battery,
enabling the RTU to operate regardless of interruptions in the mains
supply.
The RTU8 has a number of integral inputs and outputs and further
I/O´s can be added via an expansion bus. The RTU8 is compatible with
the Brodersen Series 2000/4000 product range and thus a wide variety
of expansion modules can be easily connected to the unit by standard
cables.
The unit can be programmed to perform simple control sequences
using an IEC 1131-3 (PLC) programming language. The RTU8 includes
facilities for local data logging, the process values to be logged are
defined as part of the IEC 1131-3 application program. Programming,
setup and data transfer is achieved by using the IOTOOL32.
When connected to a GSM modem the RTU offer a simple SMS
message alarm option.
The Modbus RTU protocol is used for data transfer from the RTU8 to
a PC either directly or via Hayes compatible dial-up modem, GSM, or
radio modems.
