Schleicher NGM-1600 Time Relay
What stands out about this LY2N Relay IEC255 is the clear labeling that makes wiring less confusing for me.
A nice touch is the small inset showing model 1-1618002-8 beside the wiring diagram on the packaging.
I like that it has a nice touch of being unbranded/general, so you can add your own labeling.
What stands out about the indicator light is that it keeps status visible without extra steps.
What stands out about this relay is that the type is NULL, leaving room for your own classification.
