Description
Honeywell R7847B1072 Rectification Flame Amplifier with Ampli-Check for 7800 Series, 2.0/3.0 sec FFRT, Green
Overview
The Honeywell R7847B1072 is a solid-state, plug-in rectification flame signal amplifier engineered for use with Honeywell 7800 Series relay modules in industrial and commercial burner systems. Featuring Ampli-Check self-test capability, this amplifier verifies system integrity while providing reliable flame detection using rectifying flame rods or compatible ultraviolet (UV) flame sensors.
Key Features
-
Ampli-Check Self-Test: Continuously checks amplifier and system functionality, triggering system lockout on fault detection to maintain safety compliance.
-
Selectable Flame Failure Response Time: Choose between 2.0 or 3.0-second FFRT to align with safety requirements.
-
Versatile Flame Detection: Compatible with gas rectifying flame rods (C7004, C7005, C7007, C7008, C7009), impedance matching module Q179 for long leadwire runs (>50 ft), and UV flame sensors (C7012A, C7012C).
-
Flame Signal Monitoring: Supports 0.0 to 5.0 Vdc flame signal strength measurement for commissioning and ongoing diagnostics.
-
Direct Plug-In Installation: Connects securely into Honeywell 7800 Series relay modules via keyed edge connector for reliable system integration.
-
Color-Coded Identification: Green label for quick visual identification during maintenance and system management.
-
Industrial Reliability: Suitable for demanding industrial and commercial burner management applications requiring dependable flame verification.
