Automotive relay hi motor-a hman thin relay a ni. Heng relay te hian load power sang tak an switch a, shock leh vibration resistance sang tak an nei bawk.
Automotive power supply tam zawk hi 12V a ni a, coil voltage hi a tlangpuiin 12V anga siam a ni. Battery power supply leh voltage instability vangin; boruak dinhmun khirh tak; leh pull-in voltage tlem ber (V 60% VH aia tlem emaw, a tlukpui emaw, rated operating voltage); coil overvoltage chu 1.5VH thleng phalsak a ni. Coil power consumption hi a sang hle a, a tlangpuiin 1.6–2W a ni a, hei hian temperature sang tak a tisang thin. Environment mamawh chu a khauh hle: engine compartment-ah chuan ambient temperature range chu -40℃atanga 125℃a ni a ; hmun dangah chuan -40℃atanga 85℃thleng a ni. Engine compartment-a hman tur relay-te chuan sand, tui, chi leh oil an tuar chhuak tur a ni a; vibration leh shock pawh a phur hle.
Control relay hian a bulpui pahnih a nei a, chungte chu control system leh controlled system te an ni. Control relay-in control role a thawh theih chhan chu signal engemaw, electrical, magnetic, thermal, optical physical quantity ang chi chu a control system-ah input a nih a, value engemaw zat a thlen chuan, controlled system (output circuit tia hriat bawk) controlled quantity chu zero atanga value engemaw zatah emaw, value engemaw zat atanga zero-ah emaw a inthlak nghal thei a, chu chuan control, protection, inthlunzawmna, leh thu hriatte inthlak danglamna te a ni. Control relay ziarang chu current lian tak chu current te tak te hmangin an control thei a ni.
