Honeywell Series S87 Ignition Module

The S87 is a low voltage solid state direct spark ignition control module for gas-fired furnaces boilers and heating appliances. Models are available with or without a prepurge timer. The S87 controls the gas valve monitors the main burner flame and generates a high voltage for spark ignition. The S87J uses a single electrode for spark ignition and flame sensing. Use with any gas control designed for DSI application that is rated at 2.0A or less. Includes a 30 second (minimum) delay for use with system prepurge. The S87J1034 is designed for Natural gas or Liquid Propane and has an internal high voltage spark generator.

Features: 

• External replaceable fuse protects system transformer and temperature controller.
• Automatic system lockout after trial-for-ignition if malfunction exists or main burner flame fails to ignite.
• Compact solid state components for accurate long-lasting performance.
• Convenient remote start procedure after safety shutdown control module can be reset from the remperature controller.
• Low voltage control circuit reduces wiring costs.
• Uses flame rectification principle to prove presence of main burner flame false flame signal resulting from short to ground results in safety shutdown.
