Application Setup (Four Channels °C
-
°F)
This example shows how to display the temperature of several
different thermocouples at one annunciator panel. A selector switch
(I:2/0) allows the operator to choose between displaying data in °C
and °F. A second selector switch (I:2/1) allows the operator to switch
one of the displays between the ambient temperature near the bath
and the temperature inside of the control cabinet that houses the SLC
500. Each of the displays is a 4-digit, 7-segment LED display with the
last digit representing tenths of a degree. The displays have
DC-sinking inputs and use a BCD data format.
