Application examples
16.1.7.1
Control of a 230 V device
A 230 V device is connected between neutral N (blue) and phase L (brown) of the power supply, between which there is a voltage of
230 VAC (AC voltage). A protective conductor is generally present as well (yellow/green).
If a device of this type is to be controlled via a universal switch output of Pool Relax, it must be connected as follows:
1
Output OUT1 / OUT2 terminal
2
External 230 V~ device to be switched on and off
3
House mains supply
Note: The 230 V~ supply voltage can be picked up internally from the connection compartment of Pool Relax and wired to the
controlled device.
For example, a Flockmatic
®
pump or a filtering system can be controlled according to this scheme.
If the maximum current or voltage of the universal switch output should be inadequate for a certain application, an external relay with
the required performance characteristics can be connected.
16.1.7.2
Control of a device with a DC supply voltage (DC)
For devices with a DC supply voltage, the positive line of the supply voltage is simply connected via the universal switch output of Pool
Relax:
1
Output OUT1 / OUT2 terminal
2
External device (e.g. 24 V device) to be switched on and off
3
External power supply (e.g. 24 V supply)
