Port Powered RS-232 Isolator

 

The ATC-131 optically isolates and protects the transmit and receive lines of your RS-232 port from ground loops and power surges up to 2500V RMS for one minute. The data stream is converted from an electrical pulse to an optical beam, then back to an electrical pulse. Because there is no electrical connection between the DTE and DCE sides of the isolator, the ATC-131, unlike a surge suppressor, will not pass large sustained power surges through to your equipment.

This isolator will protect both the transmit and receive lines at baud rates up to 57.6K without the need of an external power supply. Power is derived through the transmit and handshake lines. Special circuitry allows the ATC-131 to be powered regardless of the state of the handshake lines. At least one handshake line must be connected on each side of the isolator. Note that handshake line signals are not passed through the isolator.

 

  • Protect serial port, inhibit static and surge, prevent ground loop and surge damaging devices
  •  Adopt latest high voltage photoelectric parts, powerful anti-jamming capacity
  • Support RS-232 asynchronous communication standard, direct insert into RS-232 interface serially, convenient operation
  • Compact size, optional manifold signals and suitable for various devices.
