Kromschroder Burner control unit IFD258-10/1W 84621650

The Kromschroder Burner control unit IFD258-10/1W (SKU 84621650) is a control box designed for ignition and monitoring of industrial gas burners. It operates with a supply voltage of 230 V and supports flame detection via ionization or UV sensors. The safety time on start-up is 10 seconds, and the unit has a maximum of 250,000 operating cycles. It is rated IP54, weighs 682 g, and can be installed in any position. The ambient temperature range is -20 to 60 °C, and it is suitable for gas fuel type.

When selecting a burner control unit of this type, ensure the supply voltage, safety time, and flame detection method (ionization or UV) match the burner system. The unit's protection class (IP54) and cable gland size (M16) must be compatible with the installation environment. Check the ambient temperature range and relative humidity limits to ensure proper operation. The overvoltage category (III per EN 60730) should be considered for electrical safety.

Typical failures of such control units include failure to ignite, unexpected shutdowns, or lockouts. If the flame signal is lost, the unit may restart or lock out depending on the configuration. Check the flame sensor (ionization or UV) for contamination or damage, and verify the sensor voltage and current are within specified ranges. Also inspect the reset and mains buttons for wear, as they have a limited number of cycles (1000 each).
