The following connection diagram shows a combination of switched, constant power loads and external switching.
In this example drawing, Circuit 1 is being used to switch Load 1 through an external switch. Circuit 2 is being used to switch Load 2 through an external switch. Circuit 3 is being used to supply constant power to a fridge. Circuit 4 is not being used. Circuit 5 is being used to supply constant power to comms.
The trick to understanding the workings of the EGON Relay Hub is to understand that the circuits that are labeled Supply 1, Load 1, Alt. Supply 1, Switch Input 1 (all labeled on the circuit board) are all relating to the same circuit on the
Supply Power
Connect the Main Supply with an external fuse (80A max.) to a power supply. This can be a DC Hub, Battery Box, House- or Auxiliary-Battery or even your Start-Battery if you want to use this to power the electrical system that you are about to install. Now you have established the power supply to the board. Next step is to add a fuse to Supply 1 which will then power up the Alt. Supply 1 circuit and gives power to the Load 1 relay. The Load 1 relay when switched on will give power to the Load 1 pos and neg terminals.
To switch the relay, you can either use the override switch on the board which powers the activation circuit of the relay, or you can use an external switch.
Note: When the relay output is active the LED next to the Load 1 terminals will light up.
External Switch
To add an external switch, you can run a 3-core cable from the Switch input terminals on the board to your switch, For multiple switched circuits run 4, 5, 6 or 7 core cable. Add a fuse to the Power Out circuit (maximum 3amps).
This will power the Switch Inputs pos and neg terminals. These will act as a power supply for your switches. The Switch Inputs 1 through 5 will act as a signal return from the switch to activate the relay. Switch Input 1 will activate the Load 1 relay, Switch Input 2 will activate the Load 2 relay and so on.
Switched Load
To connect a switched Load (light, pump, oven, etc) use twin core cable and run it from your load to the Loads terminals on the board.
