| TTY INTERFACE 20 mA CURRENT LOOP TTY / 9600 / N / 8 / 1 CAGE CLAMP CONNECTION |
| This interface allows the connection of devices which are equipped with a 20 mA current interface. The interface is working in active, semi-active or passive operation mode. The module communicates with the control unit over 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. |
