1990-1859

High-Performance Phototransistor Optocoupler Isolation Module, containing a high-efficiency infrared emitting diode optically coupled to a monolithic silicon phototransistor behind an impenetrable optical barrier. It establishes a high-voltage electrical isolation threshold to safeguard vulnerable internal microcontroller logic from field line spikes, housed in a secure 6-pin through-hole plastic DIP package. Manufactured for Hewlett-Packard / Agilent.
