201.008.001   12V Water-Proof w/ Bracket

In diesel engines, glow-plugs are used to ignite the air/diesel mixture in cylinders. In order to increase the temperature of the cylinder chamber, especially in cold weather, glow-plugs are used prior to engine starting. A glow-plug may reach up to 1000 °C which ensures the air/diesel mixture explosion. ELO Glow Plug Relay switches current up to 120A which may be used for vehicles with up to 6 cylinders. The built-in microprocessor and temperature sensor measure ambient temperature and determine the pre-heating duration. During pre-heating an indicator lamp is lit on dashboard. Once the pre-heating is complete, the engine should be turned on. Glow-plugs are heated for an additional 20 seconds as post-heating. In extremely low temperatures, the pre-heating duration may be as long as 50 seconds. As the ambient temperature and engine temperature increase the process time decrease, which may be as low as 1 second.
