KL6401 | LON Bus Terminal

The KL6401 LON Bus Terminal enables direct connection of LON devices. The network variables of the connected devices are available for the Bus Coupler or the higher-level bus system. This simplifies the data exchange between a variety of systems and a LON network. Status LEDs directly indicate the bus status. The LON terminal operates independent of the bus system used. Several KL6401 can be used with a single Bus Coupler or a Bus Terminal Controller. The KL6401 supports 62 SNVTs. All SNVT types can be configured as input or output variable via the KS2000 software. The KS2000 software generates an XIF file that is integrated in an LON tool.
