SDT400-R
DC Input 80V
Photo-
Transistor Optocoupler
Description
The SDT400-R consists of a photo
transistor optically coupled to a light emitting diode. Optical coupling between the input IR LED and output photo
transistor allows for high isolation levels while maintaining low-level DC signal control capability. The SDT400-R provides an optically isolated method of controlling many interface applications such as telecommunications, industrial control and instrumentation circuitry.
The SDT400-R comes standard in a miniature 4 pin DIP package.
Applications
Registers, Copiers, Automatic Vending Machines System Appliances, Measuring Instruments Computer Terminals, PLCs Telecommunication Equipment, Telephones Home Appliances Digital Logic Inputs Microprocessor Inputs Switching Power Supplies
