<p>The module's built-in interface connects to any device equipped with a 20 mA current interface (TTY).</p><p>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.</p><p>The active communication channel works independently of the higher-level fieldbus system and allows full duplex operation up to 19200 baud.</p><p>The TTY interface guarantees high interference immunity via electrical isolation and driven loop current.</p>
