7A Solid State Relay is an electronic switching device that operates based on the principles of solid-state components, such as semiconductor devices, rather than traditional mechanical relays. It offers a compact and reliable solution for controlling high-current AC loads in various applications. The 7A rating indicates its maximum current-carrying capacity, making it suitable for moderate power requirements.
The provided table contains valuable information regarding the specifications of two specific models of 7A Solid State Relays: SDN-240-7 and SDN-240-7K. The “A Rating” column denotes the maximum current that these relays can handle, which is 7A in this case. The “Input” column indicates the compatible voltage range required to control the relay, which is between 3 and 32 VDC. The “Output” column specifies the range of AC voltage that can be controlled, from 24VAC to 240VAC. The table also includes various technical parameters such as control voltage, pick-up voltage, turn-on and turn-off time, drop-out voltage, input resistance, surge current, voltage drop, frequency range, dielectric strength, and more, which provide essential details for selecting the appropriate relay for specific applications.
