PFS or PFD with PROFIBUS DP interworks up to nine auto-burner controls units in the 19" standard rack. The ready-wired module subrack BGT is integrated with the PFA 700. Combined with the module subrack BGT, the PFA 700 field bus interface is compliant with the low-voltage directive and certified by the PROFIBUS user organization. The bus interface has four digital inputs and outputs, plus an integrated power supply and inputs automatic burner control units. The main voltage is from 110 v to 240 V AC and there is not any switchover necessary. DIP switches address the field bus interface.
