Telebyte RS232 to Current Loop Converter (Includes Power Supply)

Telebyte RS232 to Current Loop Converter (Includes Power Supply)

The Telebyte TB65A is an RS232-to-current-loop converter for teletypes or computers providing local terminal input through a 20 or 60 mA current loop. It drives a 20 mA loop, accepts 20 or 60 mA loop currents and operates from DC to 9.6 kbps.

Switch selection provides four operating modes: half-duplex passive loop, half-duplex active loop, full-duplex passive loop and full-duplex active loop. A wall-mounted transformer and internal power supply circuitry are included.

Features

• RS232-to-current-loop conversion.
• Loop drive current: 20 mA.
• Accepted loop currents: 20 or 60 mA.
• Four selectable duplex and active/passive loop modes.
• Wall-mounted transformer included.

Applications

• Serial connections.
• Industrial networking.
• RS232 applications.
