Black Box HS RS-232<->Current Loop Interface Converter - transceiver - RS-232

The High-Speed RS-232Current Loop Interface Converter allows an async RS-232 device to communicate with a 20-mA current-loop device. Typical current-loop devices include industrial equipment such as controllers, lathes, and data-acquisition units. The Active models let an asynchronous RS-232 device communicate with a passive current-loop device. The Active model can also be configured as a passive device to communicate with an active current-loop device.

The High-Speed RS-232Current Loop Interface Converter is great for heavy industrial environments because it's immune to noise, and it's opto-isolated. The converter is easy to configure and install. For the Active model, you only need to set two switches and you're ready to go.
