750-651/000-002

The module's built-in interface connects to any device equipped with a 20 mA 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 via electrical isolation and driven loop current.
