Description
Honeywell R7849A1015 UV Flame Amplifier for 7800 Series, 0.8/1.0 sec FFRT, No Self-Check, Purple
Overview
The Honeywell R7849A1015 is a solid-state, plug-in ultraviolet (UV) flame amplifier designed for use with Honeywell 7800 Series relay modules in industrial and commercial burner management systems. This amplifier reliably confirms flame presence using Minipeeper UV flame sensors without self-check functionality, providing a cost-effective solution for systems not requiring dynamic self-testing.
Key Features
-
Fast Flame Detection: Offers a selectable flame failure response time of 0.8 or 1.0 seconds, ensuring rapid system shutdown if flame is lost.
-
UV Flame Sensing: Compatible with Honeywell Minipeeper UV flame sensors (C7027A, C7035A, C7044) for monitoring gas and oil-fired burners.
-
Direct Plug-In Design: Connects securely to 7800 Series relay modules using a keyed printed circuit board edge connector for quick and reliable installation.
-
Flame Signal Monitoring: Supports measurement of flame signal strength within a 0.0 to 5.0 Vdc range for accurate commissioning and diagnostics.
-
Color-Coded for Identification: Purple label for quick visual identification during maintenance and service in multi-burner installations.
-
No Self-Check: Simplifies design for applications where dynamic self-checking is not required, reducing system complexity and cost.
