Product Overview
The Honeywell R7847C1005 Flame Amplifier is a rectification flame amplifier with dynamic self-check diagnostics, made for use with Honeywell 7800 Series relay modules. It offers selectable flame failure response times (FFRT) of 2.0 or 3.0 seconds, delivers a 0-5 Vdc flame signal output, and works especially well with UV flame sensors C7012E and C7012F. The module features flame signal test jacks, a keyed plug-in printed circuit board (PCB) edge connector, and green labeling to clearly indicate its detection type.
Key Features
-
Selectable FFRT: 2.0 or 3.0 second flame failure response time, providing safety and flexibility.
-
Flame Signal Output: Range from 0.0 to 5.0 Vdc, enabling accurate flame strength measurement.
-
