FlameWorx II modules provide visual and electrical output that signal flame presence or absence in a combustion chamber. The modules use an optical ultraviolet scanner to sense flame presence and function as components in a burner management system. Six versions of the control provide a multitude of operational characteristics, suitable for use in applications that require either self-check or nonself-check flame detection. One module provides two separate flame amplifiers, two 4 to 20 mA analog outputs, two SPDT flame switches, two flame-on indication LEDs, and two opto-isolated dc outputs.
