The Hella relay wiring diagram is a visual representation of how the different pins and terminals of the relay are connected to other components in the circuit. It provides valuable information on the pin assignments, current flow, and functionality of the relay.
DIGITAL VOLTAGE SENSITIVE RELAY. Operation and Installation Instructions. Dual battery charging made easy. Modern charging systems must be able to safely charge two or more different types of batteries from one engine. Now, thanks to the DVSR (Digital Voltage Sensitive Relay), 4WD, boat and caravan owners can enjoy.
The Hella solid state relay offers faster switching speeds than a standard mechanical relay as well as significantly reduced vibration sensitivity. The graph above illustrates the difference in switching response time between this solid state relay and a mechanical relay.
Application: Headlamps, auxiliary driving lamps, auxiliary fog lamps, horns, heaters, motors for fans and power windows, air-conditioners and ignition assemblies. The change-over relay changes the load path from one electrical load to another. The relay is operated by a dashboard switch.
