Product Description

The Model 8381 RS-422 Opto Isolator allows re-generating and extending the distance of RS-422 networks while maintaining optical isolation be-tween the ports. Model 8381allows for the exten-sion of RS-422 links to a maximum limit of 3300 feet or 1 km at any data rate up to 115 KBPS. Full duplex transmission is accommodated on two twisted pairs.

The Model 8381 includes TD and RD LED's as well as a built-in power supply. The power input is standard for 110 Volts/60 Hz or 220 Volts/50 Hz as an ordering option. All the inputs and outputs are via screw terminals located on the top and side surfaces of the device.

A full complement of dip switches are provided for pull up and pull down resistors on all received data lines as well as terminating loads for transmitters and receivers. The user also as the ability to configure the grounding scheme for the four wire links.
