Installation, Wiring, and Specifications
These micro PLCs feature eight DC inputs and six relay contact outputs. The
following diagram shows a typical field wiring example. The DC external power
connection uses three 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 output channels use terminals on the right side of the connector. Outputs are
organized into two banks of three normally-open relay contacts. Each bank has a
common terminal. The wiring example above shows all commons connected
together, but separate supplies and common circuits may be used. The equivalent
output circuit shows one channel of a typical bank. The relay contacts can switch AC
or DC voltages.
