Installation, Wiring, and Specifications
These micro PLCs feature eight DC inputs and six DC outputs. The following
diagram shows a typical field wiring example. The AC external power connection
uses four terminals at the left as shown.

The eight DC input channels use terminals in the middle of
the connector. Inputs are organized into two banks of four.
Each bank has an isolated common terminal, and may be
wired as either sinking or sourcing inputs. The wiring
example above shows all commons connected together,
but separate supplies and common circuits may be used.
The equivalent circuit for standard inputs is shown above,
and the high-speed input circuit is shown to the left.

The six current sinking DC output channels use terminals on the right side of the
connector. All outputs actually share the same electrical common. Note the
requirement for external power on the end (right-most) terminal. The equivalent
output circuit shows one channel of the bank of six.
