ARCHANA AC SSR (Solid State Relay) Card, 4 Channel Double-Sided PCB

This 24V operated Multi Channel SSR(Solid State Relay) Module, 240V 2A Out putwith optically isolated TRIAC can controlup to 2A at 240VAC. This is a 4 Channel SSR relay module, each relay channel has 2 separate O/P terminals, NO (Normal Open), COM (Common), named P(Phase) and L(Load). A Solid State Relay is similar to a mechanic relay where it can be controlled through a digital signal. Solid State Relay generates no noise and has a much longer lifespan in comparison to the traditional mechanic relay. When the input logic voltage is applied to the Inputs (+ and -), the P(Phase) will connect with the L(Load), allowing conductivity between them. Depending on your wiring this will turn on or off the connected load.
