Definitions
A current loop interface transmits serial data by switching on and off a 20mA
current in a conductor loop at the data bit clock. During the rest condition, or
during transmission of ”1” bits, a constant 20 mA current is flowing, whilst the
current flow is intermittent with ”0” bits.
Another name for 20mA current loop interface is TTY interface
(TeleTYpe(writer)).

Caution! The unit contains ESD-hazarded components.
