The 119802-77200 (R11EA, 12V) safety relay is a critical protection component for diesel engine electronic control systems. It protects the NGK spark plug control unit and engine control unit (ECU) by automatically disconnecting the circuit in the event of an overcurrent or short circuit, ensuring safe and stable operation of the engine's electronic systems.
Product Features
High Reliability and Durability: Utilizing high-quality electromagnetic materials and precision contact design, it ensures long-term stable operation.
Quick Response Protection: Rapidly disconnects the circuit in abnormal conditions such as overcurrent and short circuit, effectively protecting the engine's electronic equipment.
Easy Installation: Directly replaces the existing relay without requiring circuit modifications or additional tools.
Stable Performance: Reliably operates in high-temperature, high-humidity, and vibration environments.
