Automatic burner control unit IFD 258, replaces IFS 258, ignites and monitors directly ignited industrial gas burners of unlimited capacity. As a result of its fully electronic design it reacts quickly to various process requirements and is therefore also suitable for frequent cycling operation.

It can be used for atmospheric burners or forced draught burners in multiple burner applications, where a central control system is used for pre-purge and for monitoring. The burners may be modulating or stage-controlled.

The automatic burner control is suitable for operation in grounded and ungrounded systems.

The program status and the level of the flame signal can be read directly from the unit. The switch-off threshold can be set using a potentiometer.

The behaviour in the event of flame failure during operation can be selected using a switch. Either an immediate fault lock-out or a restart occurs.
