For all gas-fired heat-treatment furnaces where recirculation of the furnace atmosphere ensures a constant temperature distribution, thereby allowing shorter heating-up periods. For converting a controller signal to switch-on/switch-off times for gas burners in the case of intermittent operation, linear response between actuating signal and burner capacity.
Control of up to 8 burners,
various operating modes,
outputs with positive logic,
single- and two-zone operation,
mains voltage: 110 to 240 V AC.
