Solid State Relays

CD2450E2UR is filed application and is an Opto-isolated or Zero-Crossing Solid State Relay used as the interface between a microprocessor’s control outputs and the AC load. This device operates on the logic level at 15mA at 5 to 9V DC and features zero-crossing action.

Working Principle

CD2450E2UR consists of a photo-transistor optically coupled to an infrared emitting diode with LED between them. It uses visible LED with a narrow beam and photo transistors for its isolation and control. The optical isolator allows the transistor to be used as a switch controlled by a logic signal at its input. The transistor is then used to control the AC load. The zero-crossing feature of the CD2450E2UR eliminates arcing of the relay when it is switched by turning off the LED.

Applications

CD2450E2UR is a multi-purpose device that is used as a controller in the field of home automation, building automation, application in electrical loads, lighting control, HVAC control, position sensing, actual indicator setting etc. It also finds applications in industrial, medical, military and consumer products.

CD2450E2UR finds its use in motors, solenoids, contactors, lights, home appliance controls, audio systems, pumps, medical equipment and AC driven valves.
