Amplificateur Honeywell « R7476A1007 » à auto-vérification dynamique pour C7076

Honeywell R7476A1007 dynamic self-check ultraviolet amplifier is a solid state plug- in unit for use with flame safeguard controls. It is designed to be used only with, the adjustable sensitivity ultraviolet flame detector C7076A, which senses the ultraviolet radiation generated by a flame, in single or multiple burner ap- plications. The flame detector transmits a signal to the dynamic self-check ultraviolet amplifier, which in turn sends an amplified (2.5 to 5.5 μA) signal to the control relay. The amplifier and relay circuitry combine to provide such safety features as safe start check, safety shutdown, and rapid flame failure response time. On flame failure this simple system will cut off fuel input to the burner. A closed-loop self-checking circuit insuresuresure the integrity of both amplifier and flame detector 75 times per minute.
