Description

This is a 19″ module Fieldbus interface for interworking of up to nine automatic burner control units PFU 760 to PROFIBUS DP. The PFA 700 is integrated in the ready-wired module subrack BGT. This combination complies with the Low Voltage Directive (2006/95/EC) and the EMC Directive (2004/108/EC). Integrated power supply for the bus interface and the inputs of the automatic burner control units, code switches for addressing the fieldbus interface. This interface is for spanning lengthy distances for signal processing common in industrial furnaces and kilns.

PROFIBUS DP, as a standardized field bus system, substantially reduces development, installation, and commissioning effort and expenditure. The system facilitates handling high volumes of information to and from the control room, such as measurement, closed-loop control and open-loop control signals, or alarms can be transmitted in a concentrated manner via the network (see Applications below). Standard diagnostic tools, such as a bus tester for systematic testing of bus lines and slaves when setting up the network, and bus monitors for recording bus communication or visualization systems for display of the process, permit easy servicing.
