The R4343D/E series is a flame switch for intermittent operatio to indicate presence or absence of a flame and to be applied in commercial or industrial burner installations. light.

Flame current meter jack socket on the front permits monitoring of flame signal strength, by using any appropriate microampere meter (0-10uA minimum scale).
Plug-in mounts onto a sub base (included) for surface mounting.
Providing an indication of absence or presence of a flame in intermittent industrial oil/gas burner applications by an open or closed relay contact. 
Approvals: CE approved according EN298 (for intermittent operatio)
Protection class: IP40
Ambient temperature: -10...60C
Maximum humidity: 90%rh
R4343D models are for use with rectification type flame sensors, such as flame rods and C7012A/G UV sensors.
R4343E models are for use with Honeywell UV sensor models C7027, C7035 and C7044.
Note: The R4343D models will operate also with the "Satronic" IRD820/1020 range of infrared sensors. Note that this combination is NOT CE approved for use on installations that fall under the GAD (Gas Appliances Directive).
