KL6021 | Bus Terminal, 1-channel communication interface, serial, RS422/RS485

The KL6021 serial interface allows 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. The transmission of differential signals conforms to RS422 and guarantees high immunity to interference through electrically isolated signals.
