This serial interface I/O module connects to RS-485 interface devices.
The interface operates in accordance with the TIA/EIA-485-A, DIN 66259 standard.
The connected device communicates directly with the control unit via the fieldbus coupler. The active communication channel works independent of the higher-level fieldbus system and allows full duplex operation up to 19200 baud.
The RS-485 interface guarantees high interference immunity via electrically isolated signals.
The shield (screen) is directly connected to the DIN-rail.
