The BIALON DK01 allows control functionality in a LONWORKS® Power Line or Free-Topology network.
Via the STV bus, additional sensors and actuators can be connected and integrated into the LONWORKS® network cost-effectively. All digital inputs and outputs, as well as the sensors and actuators connected to the STV bus, are available for the entire LONWORKS® network as SNVT.
In addition to the digital I/O functions, there is a room control already completely integrated in the BIALON DK01. The room controlling objects in the module are pre-configured already, thus the controller application can be used without extra bindings.
All software objects are programmed according to LONMARK® standard. For the configuration of the
BIALON DK01, there is a free-of-charge LNS plug-in available at the STV web site.
