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.
The internal relay is designed for at least 100 000 cycles.
Inductive load management requires a parallel diode for a better contact
lifetime.
