What is the difference between LY[]N General-purpose Relays and LY[]N-D2?



This is the standard model with an indicator.


This is the model with in-built diode that suppresses the counter electromotive force generated from the DC coil of Relays.
When operating Relays with transistors, the diode eliminates problems such as deterioration and breakdown of the transistor caused by counter electromotive force.
