Automatic Burner Control Unit

Product Description

• For directly ignited burners of unlimited capacity in continuous operation pursuant to EN 746-2
• Continuous self-testing for faults
• Immediate fault lock-out or restart following flame failure available as a switchable function
• Flame control with UV sensor or ionization sensor
• Diverse installation possibilities via holes or snap mechanism for DIN rail
• Space-saving installation on site with IFD 258..I with integrated ignition
• Display for program status and flame signal intensity

• Automatic burner control unit IFD 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 stagecontrolled.
• 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.

• Control: On/Off
• Gas valve and air valve are activated simultaneously.
• The burner is ignited and monitored by a single electrode.
• In the event of a flame failure, an immediate fault lock-out occurs.

• Control: On/Off or On/High/Low/Off
• The burner BIO/BIC starts at low-fire rate.
• Once the normal operating state is reached
• The automatic burner control unit for continuous
• Operation IFD 258 will release control.
• The PLC can now pulse the air solenoid valve
• VRR in order to control the capacity between high and low fire.

• Control: On/Off/continuous
• The PLC uses the actuator IC 20 to move the air butterfly valve BVA to ignition position.
• The burner BIO/BIC starts at low-fire rate.
• Once the normal operating state is reached
• The PLC uses the actuator IC 20 and the air butterfly valve BVA to control the burner capacity.
