Information About RA890F1338
The RA890F1338 is a solid-state Honeywell flame safeguard control intended for rectification-based flame detection, such as flame-rod applications. It operates from a 120 VAC, 60 Hz supply and incorporates a safe-start check to prevent burner startup when a false flame signal is detected. The control can relight once following flame failure in an attempt to re-establish the pilot before initiating lockout. Built-in protection against ignition crossover in flame-rod systems further supports reliable operation in commercial and industrial burner installations.
Key Features:
- Protectorelay Primary Control: Provides electronic flame safeguard control for industrial and commercial burner systems.
- Flame Rectification: Uses the rectification principle to electronically detect the presence of a burner flame.
- 30-Second Safety Switch: Provides a 30-second safety switch timing for burner control sequences.
- Rapid Flame Failure Response: Responds to flame failure in approximately 0.8 seconds.
- Safe-Start Check: Prevents startup when a flame-simulating signal is detected in the flame detector circuit.
- Automatic Relight: Attempts to re-establish the pilot once after flame failure before lockout.
- Ignition Crossover Protection: Includes protection against ignition crossover in flame-rod systems.
- SPDT Alarm Relay: Provides SPDT alarm relay switching for associated monitoring and control circuits.
The RA890F1338 delivers electronic flame supervision and protective burner control for rectification-based flame detection systems.
