Solid State Relays & Relay Modules

Sai Control System caters to the needs of process control instruments and automation components in the industry. The company offers a wide range of Solid State Relays (SSR). A SSR is a static electronic switch. Unlike in an electromechanical relay where switching takes place between two moving contacts, switching in SSR takes place across the junction of semiconductor device. These devices are triac or thyristor for AC switching and transistor for DC switching. In most SSRs galvanic separation is achieved by optocouplers equipped with integrated trigger circuit (optotriac) providing the switching function required for the corresponding load type. The company manufactures SSRs from current rating 2 A to 150 A, output voltage - 240 V or 600 V AC, DC output relays with rating 110 V DC 10 A to 100 A. Relay modules: relay modules are available like 2/4/8/16 channels with base with fuse protection, relay output=1 C/O, 2 C/O contacts.
