Cosmo Solid State Relays - PCB Mount

A solid-state relay (SSR) is a type of electrical relay designed to switch electrical power on and off using an electro-mechanical contactor, but with no moving parts. It typically contains no relays, but instead a miniature circuit board that includes transistors, resistors, capacitors, and diodes in the circuit. These components are connected to a printed circuit board (PCB) through either physical or electrical connections. A solid-state relay (SSR) is thus able to control high-power devices such as electric motors and server power supplies using only a low-power control signal. Due to this, SSRs are often used in industrial applications, where size and weight are important considerations. Additionally, SSRs are advantageous in applications where there are many start/stop cycles and/or the environment is hostile, because there is no contact wear experienced with the contactor. Typically, a PCB mounted solid-state relay offers the best value if you need to control high-powered loads like motors or solenoids. Compared to leaded relays, they are smaller and consume less power, making them ideal for applications where space and power consumption is a priority. Moreover, they are more reliable as they have no contact bounce which can lead to arcing or sparking.
