Honeywell R7849B1021 UV Flame Signal Amplifier

The Honeywell R7849B1021 is a plug-in, solid-state ultraviolet (UV) flame amplifier engineered for use with Honeywell 7800 Series relay safety controls. Featuring Ampli‑Check self‑diagnostic capabilities and a selectable 2 to 3 second Flame Failure Response Time (FFRT), this module ensures reliable flame verification and enhanced burner safety in gas or oil systems.

Features:

• Flame failure response time of 0.8 or 3.0 seconds.
• Flame signal strength ranges from 0.0 to 5.0 Vdc.
• Plug into 7800 relay module through printed circuit board edge connector keyed for proper orientation.
• Flame signal test jacks to measure amplifier flame signal voltage.
• Color-coded labels identify flame detection type. Dynamic Self-Check Amplifier test the detectors and all electronic components in the flame detection system 7800 SERIES relay module locks out on safety shutdown with flame detection system failure.
• Compatible with existing Honeywell flame detectors (order separately).
