TAC Xenta 400 I/O modules 2 I/O modules in the TAC Xenta 400 series
The I/O modules are used as expansion modules for the TAC Xenta
controllers, connected to these via the common TP/FT-10 network.
The modules have different I/O configurations to suit different
applications. Some models have indicators for the digital input status
and a manual override for the digital or analog outputs. An overview of
the available models is shown below.
