Fireye 72DUVS4 Amplifier 321894-709 this microprocessor-based board provides onboardThe Fireye 72DUVS4 is a UV self check ultra violet flame amplifier designed for use with the Flame Monitor and MicroM systems, specifically engineered for continuous process applications. This module interfaces with UV1A, UV2, and UV8A scanners, utilizing a 2 to 4 second Flame Failure Response Time (FFRT) to ensure rapid shut off during a flame out event. The integrated Self Check circuitry periodically simulates a flame failure by driving a
