TTY interface

TTY interface; 9600 baud; No; 8/1 bit; Light greyThe interface integrated into the I/O module allows the connection of all devices equipped with a 20mA current interface (TTY). This interface is passive at both the sending and receiving ends. Active, semi-active or passive (with external power supply) subscribers can be connected. The module communicates with the control unit via the fieldbus coupler. The active communication channel operates independently of the higher level fieldbus system and provides full duplex operation up to 19200 baud. The TTY interface ensures high interference immunity thanks to electrical isolation and driven loop current.
