3.6 TAC Xenta 451A/452A Universal Input and
Analog Output module
The modules have eight universal inputs and two analog outputs. The
universal inputs can be used as analog inputs, digital inputs or pulse
counters.
The TAC Xenta 452A is also equipped with LED status indicators for
each universal input (when used as a digital input) and manual override
controls for the analog output values. The LED input status colors, red
or green, and the polarity (lit when contact is open or closed) can be
selected individually by altering the parameter settings in TAC Menta.
Terminals (451A, 452A) and Controls/Indicators (452A)
These modules can also be used as certified LONMARK® devices. The
configuration and use of SNVTs are explained in the 0FL-4182 Config-
uration Instruction.
