Serial Isolators are required in many Medical applications, where the patient needs to be isolated from the test's equipment, at the same time the data retrieved during the medical test needs to be delivered to the systems using isolated means for monitoring, storing and analysis.

All medical equipment should comply with IEC 60601-1, UL and other medical application standards, requiring 4KV isolation.

There are few ways to isolate serial data lines as RS232, USB and Ethernet, in some cases galvanic transformers are used, in other optical couplers and in many cases, a serial to fiber-optic cable provides ultimate isolation.  

Below you may find Isolated solutions that meet medical standards. Some qualify for these standards while others meet the 4KV isolation and are used by customers in their qualified medical applications.
