BC300 is a burner sequencer built for industrial gas burners in thermal process plants. It controls and supervises burners from 20 kW upwards, with no upper capacity limit, in both intermittent and continuous operation. Burner output is set in 1 or 2 stages, by pneumatic modulation or in cyclic operation, where the burners are fired in pulses; burners sharing a common air supply can be handled too.

The flame is supervised by ionisation with one or two electrodes, by a UV tube, by a light-dependent resistor (LDR), or by F152 with FFS07/FFS08 sensors wired to a 230 V digital contact input. The UV tube may only be used in intermittent operation. For applications under EN 746-2 in which no flame detection is needed above 750 °C furnace temperature, BC300 also offers a high-temperature mode.

On the UI300-BC-V2 panel, symbols show the burner status without relying on any language, and they stay readable from a distance and in dim light. The 10 most recent faults are kept in the unit, and settings are changed on site with LSB Remote Software. BC300 mounts directly on the burner or comes in a wall-mounting housing with the panel already fitted, and an optional fieldbus module can link it to plant automation. Its wide range of approvals allows use worldwide.
