Question
Does the input current change for Solid-state Relays with a wide rated input voltage?
Answer
In Solid-state Relays which have wide input voltages (such as G3F and G3H), the input impedance depends on the input voltage and changes in the input current. For semiconductor-driven Solid-state Relays, changes in voltage can cause malfunctions in the semiconductor, so be sure to check the actual device before usage.
This is not the case for Solid-state Relays with DC inputs that use a constant current input method (such as G3NA and G3PA).
