Note: The transistor output module AH16AN01T-5A is used in this example.
Additional remarks

Whether an output is a positive output or a negative output, and whether there is one four-digit seven-
segment display or two four-digit seven-segment displays depend on n.

The outputs on the PLC should be NPN transistors whose collectors are open collectors. In addition, an
output has to connect a pull-up resistor to the DC power supply (less than 30 VDC). Therefore, when an
output is ON, a signal of low potential is output.
