Multiple FeaturesSolid State Relay Module has the following characteristics: no spark when switching, high speed, no noise, anti-corrosion, moisture-proof, anti-vibration, long life, high reliability, electromagnetic compatibility, etc. Product ParametersThe input voltage of the built-in solid state relay is DC 3-32V, and the minimum and maximum control currents are 5mA and 15mA respectively. The output voltage range is 24-480VAC. Suitable for working at ambient temperatures of -20~75. At the same time, the resistance of their output circuit is small and the propagation speed is fast. Comes with radiatorThe single-phase solid state relay uses PC flame retardant material, which is safe and reliable. Particularly suitable for corrosion, humidity, dust and other harsh environments, as well as frequent switching, the AC contactor is an updated alternative. The use of high-strength aluminum alloy heat dissipation greatly improves the heat dissipation effect and avoids the tedious installation of 2 installation methods There is a guide rail mounting part at the bottom, which can be installed and fixed by guide rail or screw installation. Easy to install, compact, convenient and practical. Wide applicationSolid state relays are widely used in microcomputer control, LED lighting, electric heating equipment, automatic curtains, automatic door switches, crane systems and other industries.
