Description
The Fenwal 35 705600 005 120 VAC Direct Spark Ignition Control and its equivalent listings are OEM grade Direct Spark Ignition (DSI) control modules designed to provide safe, reliable burner ignition and flame supervision for gas fired appliances and heating equipment. Built with a microprocessor based circuit, this 120 VAC ignition control delivers precise timing sequences, robust flame sensing, and helpful diagnostics — essential for professional HVAC, commercial, and industrial applications.
Main Features
- Direct Spark Ignition (DSI): Ignites burners using an electronic spark without a standing pilot, improving efficiency and start up reliability.
- 120 VAC Power: Designed for systems that use standard line voltage, such as furnaces, crop dryers, commercial heaters, and gas appliances.
- Microprocessor Timing Logic: Provides accurate control of ignition sequences and flame sensing for consistent performance.
- 10 Second Trial for Ignition (TFI): Allows a controlled window for flame establishment before lockout to enhance safety.
- Flame Sense & Diagnostics: On board LED indicators help technicians quickly identify errors and simplify troubleshooting.
- Local Sense with Valve Relay: Includes a 120 VAC gas valve relay for integrated control of burner operations.
- Rugged Design: Conformal coating and quality construction help the module withstand moisture and vibration in demanding environments.
