Wago 750-651 fieldbus module

<b>Serial TTY Interface, 9600 baud, None, 8/1 bits</b>
The interface integrated into the I/O module allows the connection of any device which is equipped with a 20mA current interface (TTY).

This interface is passive both at the sending and at the receiving end. It can be connected with active, semi-active or passive (with external power source) subscribers. The module communicates with the control unit via the fieldbus coupler.

The active communication channel works independently of the higher-level fieldbus system and allows full duplex operation up to 19200 baud.

The TTY interface guarantees high interference immunity because of the electrical isolation and the driven loop current.
