SSR-40DD DC 3-32V Input to DC 5-200V Solid state relay This is DC To DC SSR-40DD 40A Solid State Relay Module offers an input of 3V-32V DC with an output voltage of 5V -200VDC at an output current of 40A. A solid-state relay (SSR) is simply an IC that functions as a mechanical relay. The only difference between this SSR with the mechanical relay is that there is no moving contact in a Solid-State Relay. This SSR allows us to control high-voltage AC loads from lower voltage DC control circuitry. This is achieved by using infrared light as the ‘contact,’. In short, a solid-state relay is just an IR LED and a photometric enclosed into a little box. Thus we make use of the Phototriac coupler to turn it ON and OFF. Solid-state relays offer numerous advantages over mechanical relays. One such advantage is that they can be switched by a much lower voltage and at a much lower current than most mechanical relays. Also, as there are no moving contacts, solid-state relays switched much faster and for much longer periods without wearing out. Each one of these relays is designed with four screw terminals for use with ring or fork connectors. And enclosed in a plastic cover that slides over the top of the relay to protect the terminals. This Solid State Relay module features long service life and high reliability with reduced electromagnetic interference. Moreover, its compact size design offers users maximum simplicity.
