SAT400
AC Input
60V
Photo-Transistor Optocoupler
Description
The SAT400 consists of a phototransistor optically coupled
to two light emitting diodes. Optical coupling between the
two input IR LEDs and output phototransistor allows for
high isolation levels while maintaining low-level AC signal
control capability. The SAT400 provides an optically
isolated method of controlling many interface applications
such as telecommunications, industrial control and
instrumentation circuitry.
The SAT400 comes standard in a miniature 4 pin DIP
package.
