Fieldbus Terminals
Serial Port TTY, 20 mA Current Loop
Product Description

 The KL6011 serial interface enables the connection of units with a 20 mA current
interface. The interface operates in passive mode. The unit connected to the KL6011
terminal communicates with the controller via the bus coupler. The active communication
channel operates independently of the higher-level bus system in full duplex mode at a
rate of up to 19,200 baud. The current interface (TTY) guarantees a high degree of
insusceptibility to faults thanks to electrically isolated signals with an integrated
current.
