Honeywell 7800 SERIES Burner Controls Flame Signal Amplifiers R7847A1025/U module

Solid state plug-in amplifiers that respond to flame detector inputs
to indicate the presence of flame when used with 7800 SERIES
relay modules.
• Flame failure response time of 0.8 or 3.0 seconds (1.0 or 2.0 for CE
approved devices).
• Flame signal strength ranges from 0.0 to 5.0 Vdc.
• Plug into 7800 relay module through printed circuit board edge
connector keyed for proper orientation.
• Flame signal test jacks to measure amplifier flame signal voltage.
• Color-coded labels identify flame detection type.
• Dynamic Self-Check Amplifier test the detectors and all electronic
components in the flame detection system.
• Ampli-check tests the amplifier and 7800 SERIES Relay.
• None (standard) is just tested at normal system startup.
• 7800 SERIES relay module locks out on safety shutdown with flame
detection system failure.
• Compatible with existing Honeywell flame detectors (order
separately).
