Description
Honeywell R7849B1021 UV Flame Amplifier with Ampli-Check for 7800 Series, Selectable 2.0/3.0 sec FFRT, Purple
Overview
The Honeywell R7849B1021 is a solid-state, plug-in ultraviolet (UV) flame signal amplifier engineered for use with Honeywell 7800 Series relay modules in industrial and commercial burner systems. Designed to confirm flame presence using Minipeeper UV flame sensors, this amplifier ensures safety and system reliability through Ampli-Check continuous self-testing.
Key Features
-
Ampli-Check Self-Test: Monitors amplifier functionality and system integrity, triggering a safety lockout in the event of a system fault to maintain compliance and safety.
-
Selectable Flame Failure Response Time: Offers 2.0 or 3.0-second flame failure response time to meet varied system safety requirements.
-
UV Flame Detection: Interfaces with Honeywell Minipeeper UV flame sensors (C7027A, C7035A, C7044) for reliable detection in gas and oil burner applications.
-
Flame Signal Monitoring: Supports flame signal strength measurements ranging from 0.0 to 5.0 Vdc for accurate diagnostics and system commissioning.
-
Plug-and-Play Integration: Installs easily into Honeywell 7800 Series relay modules with a keyed printed circuit board edge connector for secure, error-free connection.
-
Color-Coded for Quick Identification: Purple labeling ensures easy identification during service and maintenance in multi-system environments.
-
Dependable Performance: Delivers reliable operation in demanding industrial and commercial burner management systems requiring UV flame detection.
