Field Bus Interface PFA 700A
This is a 19" module for networking up to nine automatic burner control units PFS, PFD, or PFU 778L with industrial communication networks. 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.
Features
- Simple control of up to nine automatic burner control units PFS, PFD or PFU via one line
- Saves installation and wiring costs
- Certified for PROFIBUS DP
- Four digital inputs and four digital outputs for free use
- Remote diagnosis option for high availability
- Easy expansion of networked installations

PROFIBUS DP, as a standardised field bus system, substantially reduces development, installation and commissioning effort and expenditure in such cases by comparison with conventional wiring (top image). A high volume of information from and to the control room, such as measurement, closedloop control and open-loop control signals or alarms, can be transmitted in concentrated manner via the network (bottom image). |
