An Engine Electronic Control Module Relay consists of a coil, multiple sets of contacts, and a control circuit. The relay is enclosed in a hermetically sealed to prevent damage from external elements. The Four-Pole Double-Throw Relay is used to facilitate the Electronic Control Module's (ECM) control over engine functions. The ECM sends electrical signals to the relay, which then switches the appropriate circuits on or off based on the ECM's commands.Attributes:• Provided with -40°C to 70°C Ambient Temperature range• Provides airtight and watertight seal to protect the relay componentsApplications:An Engine Electronic Control Module Relay is made to integrate seamlessly with the machine's engine control system. It works in conjunction with other sensors, actuators, and control modules to ensure proper engine operation and performance.
