Product Overview
A practical path for bringing installed serial equipment into modern industrial data networks.
The DTIB-0708 is an inline RS232 optoelectronic isolator that preserves asynchronous, full-duplex transparent communication between serial devices.
It is self-powered through the serial connection and helps protect connected RS232 equipment from ground-loop voltage, surge, static electricity, inductive lightning and hot-plugging effects described by the legacy product source.
