A 12 volt relay often called a manual split charge relay is an electronic device that uses an electromagnet to pull a set of contacts that make or break a circuit.
Durite split charge relay diagram.
Durite s wide range of relays and flasher units cover 12v and 24v applications.
I ve done a step by step on how to fit the split.
I have left boxes on the diagram on the left to help you with your measurements.
Have a look at the diagram above to see the basic wiring diagram of your voltage sensed split charge kit.
How does a 12 volt relay work.
Durite 12v 140a voltage sensitive relay with red led indicator relay makes at 13 3v and breaks at 12 8v ce approved allows split charging of second battery.
Thanks for checking out my how to install a durite split charge relay into a vw transporter t5.
In addition there are 9 available programmes allowing the user to set the charging protection voltages to suit their requirements.
Connect the cable from the two batteries to the split charge relay.
To to this remove the back plastic cover and unscrew the nuts.
The durite smart relay has been designed to be used with the latest range of vehicles fitted with smart alternators and regenerative braking systems.
A 12 volt relay is the same type of relay that you would find in many 12 volt electrical systems.
For some reason the relay i got didn t have any gaps on the plastic edges to place the cables.
Allows split charging of second battery bank without discharging the primary start battery.
Connect the cables to the relay.
Durite 140amp 12 volt split charge vsr relay 12v voltage sensitive relay 140a 12 volt 140 amp with red led indicator.
Place the leads and screw the nuts back in.
Plus enjoy more flexibility with our customisable made to order programmable timer relays.
This system uses a heavy duty version of a simple make and break relay the coil of which is energised by a signal that is only 12v when the engine is running usually the charge signal wire from the alternator.
