Great prices on RS232, RS422, RS485 Isolation products for short haul modems, interface converters, and more.


Our Isolation product line uses Opto Isolators to provide protection from ground loops, high voltage and noise. Isolation is an important consideration if a system uses different power sources, has noisy signals or must operate at different ground potentials. Check out our interface converters, isolated line drivers, optically isolated link extenders and more.
