HONEYWELL RA890G1245 Burner Control Relay

Product Description

Honeywell RA890G1245 is a Protectorelay™ Primary Burner Control Relay designed for industrial and commercial gas, oil, or combination gas-oil burner systems. It provides flame safeguard protection by continuously monitoring the burner flame and safely shutting down the fuel supply if a flame failure is detected.

The RA890G series is intended for use with compatible Honeywell flame amplifiers, UV flame detectors, flame rods, or photocells, depending on the system configuration. It is widely used in boilers, furnaces, ovens, kilns, and other combustion equipment requiring reliable flame supervision.

Notes

• RA890G1245 is a burner flame safeguard primary control relay, not a general-purpose industrial relay.
• Verify the supply voltage (220 VAC), flame amplifier, flame detector type, and mounting base compatibility before installation.
• Functional flame safety testing should always be performed after installation or replacement.
• Honeywell recommends migration to the 7800 Series for many legacy RA890G applications where appropriate.
