Durite Split Charge Relay Wiring

Instillation guide for a 12v voltage sense split charge relay system thank you for purchasing this kit from simply split charge.

Durite split charge relay wiring.

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. Durite s wide range of relays and flasher units cover 12v and 24v applications. 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. I have left boxes on the diagram on the left to help you with your measurements.

Plus enjoy more flexibility with our customisable made to order programmable timer relays. Designed to charge and maintain a 24 volt auxiliary battery from a 12 volt dc system. In addition there are 9 available programmes allowing the user to set the charging protection voltages to suit their requirements. The durite smart relay has been designed to be used with the latest range of vehicles fitted with smart alternators and regenerative braking systems.

Have a look at the diagram above to see the basic wiring diagram of your voltage sensed split charge kit. To to this remove the back plastic cover and unscrew the nuts.

A 12 volt relay is the same type of relay that you would find in many 12 volt electrical systems.

How does a 12 volt relay work. 0 727 23 durite 12v 70a 20a split charge relay 12v 70a 20a split charge relay isolates fridge circuit 2 x 2 8mm 1 x 6 3mm and 2 x 9 5mm terminals replaces lucas srb630. Allows split charging of second battery bank without discharging the primary start battery. Connect the cable from the two batteries to the split charge relay.

It has a three stage micro processor controlled charging system and uses voltage sensing for automatic cut in and drop out of charge from the 12 volt system so will not charge the 24 volt auxiliary battery until the 12 volt vehicle battery is charged or being. Place the leads and screw the nuts back in. For some reason the relay i got didn t have any gaps on the plastic edges to place the cables.
