Relay is a kind of when the input (electrical, magnetic, acoustic, optical, thermal) reaches a certain value, the output will change by leaps and bounds of the automatic control device. And automobile relay is used in the automobile relay, the relay switching load power is big, high resistance to impact and vibration resistance. The power use 12 v car, coil voltage are mostly designed for 12 v. Because it is battery power supply, voltage instability; Poor environmental conditions, pull-up voltage V 60% or less VH (fixed working voltage); 1.5 the VH coil overvoltage allowed. Coil power consumption is bigger, average 1.6 ~ 2 w, higher temperature rise. Environment is quite demanding: in the engine compartment, ambient temperature range for - 40 ℃ ~ 125 ℃, environment temperature range for other position - 40 ℃ ~ 85 ℃; Used in the engine cabin relay wants to be able to withstand the enroach on of sand dust, water, salt, oil; Vibration and impact is quite strict.
