P531



Model P531 signal processors are fail-safe, self checking signal processors capable of monitoring two S55XBE and one S70X series viewing heads simultaneously, and when used with P532UI, it can display UV and IR flame count separately for S550BE viewing heads. The processors offer independent gain adjustments, and for S552BE and S550BE, multiple frequency settings. P531 are ideally suited for tangentially fired boilers where two viewing heads are required for main burner and S70X for side or horn igniters.
