Automatic Burner Control Unit IFD 258

The automatic burner control unit IFD 258 ignites and monitors gas burners. Because of its fully electronic design, it reacts quickly to various process requirements and is suitable for frequent cycling operation.

It can be used for directly ignited industrial burners of unlimited capacity. The burners may be modulating or stage-controlled.

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

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

	Applications Click on images for close-up view. Forced draught burners 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. Two-stage-controlled burner 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 VR..R in order to control the capacity between high and low fire. Modulating-controlled burner 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.
