Fotek SSR 40DA Solid State Relay

This is SSR 40DA Single-phase Solid State Relay. It can be driven by Arduino directly without any expanding circuit because of its built-in opto-couple. The plastic protective cover makes it a safer relay module.

SSR solid state relay uses inflaming retarding engineering plastic shell, epoxy resin encapsulation, and screw terminal connection. This series solid state relay has high structural strength, impact resistance, and strong resistance to vibratility. The low input drives current makes connecting with the computer terminals and various digital programmable interface circuits convenient.

It is widely used in automation control fields such as petrochemical equipment, food machinery, packaging machinery, textile machinery, CNC machine, plastic machinery, fitness equipment, and recreational facilities, especially suitable for severe environments like corrosion, moisture, dust prevention, explosive requirements, and frequent switch occasions. SSR series solid state relay is updated replacement products of a.c. contactor.
