This SICK relay has a neat, simple look that I appreciate on the bench.
Solid State Relay SNC-R2025-501 70-140VAC Input, 48-300VAC 25A Output (H3C2)
You will find that the 70*20*18mm / 2.75*0.78*0.7" size works well in modular builds.
A nice touch is the labeling on the Relay Switch model, which makes installation less confusing.
I appreciate remote control here, a nice touch that helps when you want to avoid constant trips to the panel.
