The 8950920000 is a TERMOPTO solid-state relay designed for switching DC loads using a single normally open (NO) transistor contact. It operates with a rated control voltage of 24 V DC and can switch loads from 5 to 48 V DC with a continuous current of up to 500 mA. Housed in a compact 6.1 mm wide enclosure with screw connections, this relay includes protective circuits such as a varistor and reverse polarity protection on the control side and a free-wheel diode on the load side. The device provides fast switching with a switch-on delay of less than 20 µs, a green LED for status indication, and a low voltage drop of less than 1V at maximum load. Its enclosed IP20 design and wide operating temperature range make it a reliable component for various industrial automation and control applications.
