Product Details:
Flame failure response time: 0.8 or 1 sec
Type: Rectification

Honeywell R7847A1025 flame amplifier:
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).
