3.5 TAC Xenta 451/452 Analog Input and Output
module
The modules have four universal inputs, four thermistor inputs and two
analog outputs. The universal inputs can be used as analog inputs, dig-
ital inputs or pulse counters.
The TAC Xenta 452 is also equipped with LED status indicators, one
for each universal input, when used as a digital input, and manual over-
ride controls for the analog output values. The LED input status colors,
red or green, can be selected individually by setting switches under the
front cover.
