Honeywell RA890F1353 protectorelay:
Primary control provides solid state, electronic flame safeguard protection for industrial and commercial single or dual fuel burners for rectification type flame detection.
*Uses rectification principle of electronic flame detection.
* Replaces RA890E in most applications and mounts on same Q270A1024 Subbase.
* Recycles if flame signal lost while in Run. Failure to establish pilot results in a lockout.
* Safe-start check prevents start-up if flame-simulating failure occurs in flame detector circuit
* Includes built-in protection against ignition crossover in flame rod systems.
* Includes SPDT alarm contacts.
* Solid state circuitry.
* Mounts and removes easily through use of captive mounting screws.
* Mounting base is made of strong thermoplastic.
