Autonics SRS1-B1202R-2 Relay

Autonics SRS1-B1202R-2 is a socket-type, two-channel solid-state relay for single-phase AC loads, designed for use with the LY2 universal socket. It accepts a DC control signal in the 4–30 V range and provides two independent output circuits that switch 90–240 VAC (50/60 Hz) with a rated load current of 2 A per circuit. The relay offers two output circuits, with a dielectric withstand of 2,500 VAC between the input and load sides, and it features random-turn-on control, meaning the load can be energized at any point in the AC cycle when the DC input is applied. Operating ambient temperature range is -20 to 80°C (storage -30 to 100°C) and ambient humidity is 45–85% RH (storage 45–85% RH). Weight is about 30 g per unit, with a typical 10-unit carton weighing roughly 400 g. In short, SRS1-B1202R-2 provides solid-state switching for two AC loads from a low-voltage DC signal, offering faster switching and longer life than mechanical relays while maintaining electrical isolation and high dielectric safety.
