TAC Xenta 280
A compact, freely programmable controller which is LonMark
®
certified and
has fixed inputs and outputs. The controller is available in three different
versions:
• TAC Xenta 281 (12 physical inputs/outputs)
• TAC Xenta 282 (16 physical inputs/outputs)
• TAC Xenta 283 (12 physical inputs/outputs)
The controllers can be easily programmed using the graphical programming
tool TAC Menta. The controllers can be used in a stand-alone system, where
the TAC Xenta OP can be used for displaying and operating the controller.
Controllers can alternatively be used in larger LonWorks
®
networks.
