X10 24 VDC power connection
At the X10 plug, the 24 Volt industrial voltage is fed, filtered and applied
to the power supply unit.
The power supply unit transforms the 24 V into different voltages.

The pins 1 and 2 or 3 and 4 are connected with each other on the printed
board. Per contact, approx. 5 A at 70 °C can be transmitted.

The connection is executed with reverse battery protection.
The rho4.0 is provided with a DC/DC converter with galvanic separation

Besides the voltage tolerances, a whole alternating voltage component
with a peak value of 5 % of the nominal value is allowed.
