SAT450 - Solid State Optronics

SAT450
AC Input
80V
Photo-Transistor Optocoupler
Description
Features
The SAT450 consists of a phototransistor optically coupled
to two light emitting diodes. Optical coupling between the
input IR LEDs and output phototransistor allows for high
isolation levels while maintaining low-level AC or DC signal
control capability. The SAT450 provides an optically
isolated method of controlling many interface applications
such as telecommunications, industrial control and
instrumentation circuitry.
