RS-232 Isolator

It is an industrial grade (wide temperature range with surge & static protection) port-powered RS-232 isolator.

The unit optically isolates seven (7) RS-232 lines (TX, RX, RTS, CTS, DTR, DSR and GND), which effectively protects your RS-232 devices from ground loops, transient surges and spikes.


1. Industrial grade with wide temperature range, surge and static protection.

2. Port-powered, no external power required.

3. Optical isolation protects RS-232 devices from ground loops, transient, surges and spikes.

4. Optical isolation eliminates ground loop and noise problems.

5. Plug and play (hot-pluggable, data format auto-sensing and self-adjusting).

6. Built-in surge protection, static protection and circuit protection.

7. Surface Mount Technology manufactured to ISO-9001 standards.

8. CE certified.
