RS422 Interface Modül

The KL6021 serial interface allows devices with RS422 or RS485 interface to be connected. The device connected to the terminal communicates with the automation device via the Bus Coupler. The active communication channel operates independently of the higher-level bus system in full or half duplex mode at up to 19,200 baud. The differential signal transmission according to RS422 guarantees high immunity to interference through electrically isolated signals.
