Nominal characteristics of relay
Load characteristics:
 1 A max @ 30 VDC (according to the safety extra low voltage requirements
independently of the power supply),
 Resistive load or inductive load; see warning information hereafter for inductive
load.
Inductive load management requires a parallel diode for a better contact
lifetime.
