5V 2A 4 Channel SSR Solid State Relay Module (Low level Trigger)

• Has been assembled, and electrical test passed.
• Led indicator for each relay.
• Operating Voltage: 5V
• Operating Current: 12.5mA
• Maximum Load: 2A @ 240VAC

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 compared to the traditional mechanic relay.

When the input logic voltage is applied to the coil, the NC will disconnect from the COM breaking the conductivity between the two. At the same time, the NO will connect with the COM allowing conductivity between them. Depending on your wiring this will turn on or off the connected load.
