Beckhoff KL6021 Bus Terminal Bus Terminal
Serial interface RS422/RS485, Data transfer channels: TxD and RxD, full/half duplex, Data transfer rates: 1,2-19,2-kbaud, default: 9,600 baud, 8 data bits, no parity and one stop bit
The KL6021 and KL6041 serial interfaces allow devices with an 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 or 115.2 kbaud (KL6041). The transmission of differential signals conforms to RS422 and guarantees high immunity to interference through electrically isolated signals.
