4.8 Optically Isolated Input Settings
The TTC-1000 may be optionally equipped with up to 14 optically isolated inputs.
Each input contains a limiting resistor that allows these inputs to recognize a
wide range of input voltage of 38 to 160 Volts AC or DC as being picked up.
Inputs 1 and 2 are scanned every 32 milliseconds. Inputs 3 through 14 are
scanned slightly less frequently. Every input’s contact chatter is debounced by
requiring the input be stable for two scans before the new state is recognized.
Inputs may be assigned to any output using the programmable logic.
