Honeywell R7847B1072 Flame Amplifier – Ampli-Check Rectification Module (2.0 / 3.0-Second FFRT)
Product Overview
The Honeywell R7847B1072 Flame Amplifier is a rectification flame amplifier module with Ampli-Check self-checking functionality, built for use with Honeywell 7800 Series relay modules. It offers selectable flame failure response times (FFRT) of 2.0 or 3.0 seconds, delivering reliable flame detection through flame rods or compatible UV flame sensors. This module provides a 0-5 Vdc flame signal output and includes flame signal test jacks for verification. Color coded green for rectification detection type, this amplifier enhances burner safety and performance.
Key Features
Selectable FFRT: 2.0 or 3.0 second flame failure response time
Flame signal output range of 0.0 to 5.0 Vdc for accurate flame strength monitoring
Ampli-Check self-checking capability to verify amplifier and sensor integrity
Compatible detection types: gas rectifying flame rods (C7004, C7005, C7007, C7008, C7009), impedance matching rod Q179 for long leadwire runs (>50 ft), and ultraviolet (UV) flame sensors such as C7012A / C7012C
Plug-in keyed PCB edge connector for proper orientation into 7800 Series relay modules
Flame signal test jacks included for measuring amplifier flame signal voltage
Green label identifies this module as a rectification flame amplifier type
