4 Channel 24V Relay Module Solid State High Level SSR DC Control 250V 2A with Resistive Fuse
This 4 Channel 24V Solid State Relay Module functions similarly to a mechanical relay but utilizes solid-state components. It enables the control of high-voltage AC loads using lower voltage DC control circuitry. Unlike mechanical relays, solid-state relays (SSRs) employ infrared light for contact, encapsulating an IR LED and a photo Triac within a compact enclosure.
Solid-state relays offer several advantages over their mechanical counterparts. They generate minimal noise and boast a significantly longer lifespan. Additionally, SSRs can be triggered by lower voltages and currents. Moreover, due to the absence of moving parts, solid-state relays can switch much faster and endure prolonged operation without wearing out.
In essence, the 4 Channel 24V Solid State Relay Module provides efficient and durable control over high-voltage AC loads, making it a preferred choice for various applications requiring reliable switching capabilities.
