CIRCUITRY Negative True Logic
Modules have either a polarized (Figure 3) or non-
polarized (Figure 4) input. When replacing mod-
ules from another manufacturer, check the wiring
diagrams below against the application circuit. In
many instances, polarized modules can be used
to replace non-polarized modules if the polarity
matches the application, thus providing faster
turn-on.
Typical Logic Supply Current Versus Logic
Supply Voltage
For Figures 1 and 2, all values were measured at
25˚C. The logic supply voltage continuum repre-
sents the voltage range for each of the three
nominal voltages (5, 15, and 24 Vdc).
