HW RA890G-1260

Commercial/Industrial Electromechanical Burner Controls

RA890G Protectorelay Primary Control - Ultraviolet Flame Detection

• Primary control provides solid state, electronic flame safeguard protection
  for industrial and commercial single or dual fuel burners applications
  using Ultraviolet flame detectors
• Design for interrupted ignition with intermittent pilot on gas burners,
  and interrupted or intermittent ignition on oil burners
• Use with a C7027, C7035 or C7044 Minipeeper Ultraviolet Flame Detector
  for flame sensing
• 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 SPDT alarm contacts
• Solid state circuitry, eliminates warm-up and increases resistance to vibration
• Mounting base is made of strong thermoplastic
• Mounts and removes through use of captive mounting screws
• Frequency: 50/60Hz
• Temperature range: -20° to 105°F (-29° to 41°C) @ 50Hz
  -20° to 115°F (-29° to 46°C) @ 60 Hz
• Factory Mutual Approved
• UL Listed 120V models only, CSA certified
