Features [Fast heat conduction]: The solid state relay adopts high-purity copper substrate, which effectively improves the thermal conductivity by 1.5 times. [Specifications]: The control method is simple and convenient, load voltage: 0~250V AC; control voltage: 0-10V DC; pay attention to insulation protection. [Good performance]: High-quality chip, strong performance, long service life, high switching speed, high-performance optocoupler with high withstand voltage. [Durable]: The shell is made of high-temperature-resistant and flame-retardant materials. After being subjected to high temperature, the sign will not deform or wrinkle, and the seams are inseparable. The screws are made of high-toughness anti-rust material, which is not easy to break and slide. [Wide application]: computer peripheral interface equipment, constant temperature system, temperature adjustment, electric furnace heating control, motor control, numerical control machinery, remote control system, industrial automation equipment; signal lights, dimming, scintillators, lighting stage lighting control systems.
