Please provide full product details for 1.Relays so I can write a complete, optimized description. The current input lacks specifications needed to ensure accuracy and consistency with the original product. Include as many of the following as possible: Brand name and model numbers Relay type (electromechanical or solidstate) Coil voltage and coil resistance Contact configuration (eg, SPST, SPDT, DPDT) and contact ratings (voltage, current, max switching power) Contact materials and operating characteristics (pickup/dropout, materials) Package style and size (throughhole, SMT, PCB footprint, DIN rail, etc.) Mounting/termination options (screw terminals, plugin, solder pads) Insulation/Isolation voltage (Viso) and dielectric strength Operating temperature range and humidity Mechanical dimensions and enclosure material Certifications (UL, CE, RoHS, CSA, etc.) Mechanical and electrical life ratings Typical applications or recommended use cases Special features (indicator LED, suppression diode, zerocross switching, surge protection, builtin coil protection) Wiring/configuration examples or compatibility notes and packaging details If you can't provide all details, share as many as you have and I'll draft a solid, conversionfocused description with placeholders for missing specs. Also indicate the target audience and any preferred tone (professional, technical, accessible).
