Kromschroder Control box IFD258-5/1WI 84621635

The Kromschroder Control box IFD258-5/1WI (SKU 84621635) is an electronic control unit for industrial gas burners, designed for direct ignition and flame monitoring without capacity limitations. It operates on a 230 V supply voltage and features a safety time of 5 seconds on start-up. The device supports both ionization and UV flame detection, and is rated IP54 for protection. It is suitable for ambient temperatures from -20 to 60 °C and complies with safety standard EN 60730. The control box is hardwired and has a maximum of 250,000 operating cycles.

Parts of this type are selected by matching the supply voltage, safety time, and flame detector type (ionization or UV) to the burner system. The control box must be hardwired, with correct phase and neutral orientation, and proper grounding is essential. Installation position is flexible, but the cable gland size (M16) and overvoltage category (III) must be compatible with the existing wiring. Ensure the ambient temperature and humidity conditions meet the specified limits.

Typical failures include loss of flame signal, which may cause immediate lock-out or restart depending on the switchable setting. The equipment may fail to ignite or shut down unexpectedly. Check the flame sensor (ionization or UV) for contamination or damage, and verify the supply voltage and wiring connections. The reset button and mains button have a limited cycle life of 1000 cycles each, so frequent resets may indicate a need for replacement.
