KL6011 | Serial interface TTY, 20 mA current loop
The KL6011 serial interface allows devices with a 20 mA current interface to be connected. The interface operates passively. The device connected to the KL6011 terminal communicates with the automation device via the Bus Coupler. The active communication channel operates independently of the higher-level bus system in full duplex mode at up to 19,200 baud. The current interface (TTY) guarantees high immunity to interference through electrically isolated signals with injected current.
