Optically separates an RS-232 line from ground loops and voltage surges
A port-powered optical isolator that sits in series with an RS-232 line. It splits the transmit and receive lines and leaves no electrical path between the DTE and DCE sides, so a sustained power surge never travels through to the equipment behind it.

Key specifications
Interface and connectorsComplies with the EIA RS-232 and CCITT v.24 asynchronous protocol. A DB9 male connector serves the input and a DB9 female connector the output.
Operating modeRuns asynchronous full duplex traffic.
Transmission speedProtects both the transmit and the receive line at baud rates from 0 to 57.6 kbps.
IsolationHolds the two sides apart up to 2500 V continuous and 7500 V impulse.
Power inputDraws its power from the RS-232 port (TXD, RTS or DTR) and asks for no external supply. Dedicated circuitry keeps the unit powered whatever the handshake lines do.
Housing and environmentThe plastic shell works from -20 °C to 70 °C and across 5% to 95% relative humidity.
Handshake signals do not pass through the isolator; each side of the isolator needs at least one handshake line.
