The Isocom Components 2004 LTD IS2801-4 Optoisolators - Transistor, Photovoltaic Output are ideal for isolating low-power circuits from high-powered ones. Offering an isolation voltage rating of 3000 Vrms (50 & 60 Hz for 1 min.), these optoisolators feature four channels and transistor outputs, with excellent current transfer ratios. The high-performance isolate and IC technology provides immunity from common-mode voltage and other electrical disturbances, offering superior signal transmission on long line lengths with increased noise margin. The IS2801-4 is RoHS-compliant and provides superior protection from noisy signals, making it an excellent choice for applications such as motor control and input/output signal transmission.
