11. RS-232C Interface (TD-260T AC(232C) / TD-260T DC(232C))

The RS-232C interface loads readings and states from and also
saves set values into the TD-260T. It connects the TD-260T to
a computer, process controller, sequencer, or equivalent, for
controlling, summarizing, recording, or any other processing
purposes.
The TD-260T internal circuit and external connection circuit are
electrically isolated with a photocoupler.
