Port Pin Assignments

The PLC-16.PCI has several different cable and terminal block options. The card itself has a high-density 44-pin
connector (HD44), unlike many competitive products. This allows both poles (NO/NC) of the Form C relay to be
accessed as well as each input of the optically isolated input circuit to be represented as a unique pin on the
connector. The following table shows the correlation between pins on the HD44 and their specific function.
