DL06 Micro PLCs with DC inputs are particularly
flexible because they can be wired as either sinking
or sourcing. The dual diodes (shown to the right)
allow 10.8–26.4 VDC. The target applications are
+12VDC and +24VDC. You can actually wire each
group of inputs associated common group of inputs
as DC sinking and the other half as DC sourcing.
Inputs grouped by a common must be all sinking or
all sourcing.
In the first and simplest example below, all commons
are connected together and all inputs are sinking.
