2.4.2 Digital inputs
Digital (transistor) inputs can be located on either the base unit or optional I/O expansion
modules.
Figure 2-19 AC-type input connections (base unit shown)
Input devices can be connected to DC-powered controllers as either a sinking (NPN) input,
with the return switched, or sourcing (PNP) input, with the signal switched.
A common power source can be used for the power supply and I/O devices, or the I/O
devices can be powered from a separate power supply. The I/O channels are optically
isolated from the input power.
Figure 2-20 PNP-type input connection (base unit shown)
Figure 2-21 NPN-type input connection (base unit shown)
Terminals are labeled as COM, shared by all channels, or
I
x where x indicates the channel
number. Channel numbering starts with 0.
COM I0 I1 I2 I3 I4 I5 I6 I7
Do not mix input connection methodology. All inputs must be wired as PNP or NPN.
PNP and NPN inputs apply to DC connections only.
