Connecting an aux output
The contact block has three terminals which are used for the aux contact out function.
(location details). The contact output is a form C contact closure. (terminal details)
To connect an external device to an aux contact out on the N-111, use two wires, 16-28
AWG in size. Strip about ¼” of the insulation from the end of the wires before inserting
them into the terminal blocks. Tighten the terminal screws to secure the wires in the
terminal block.
Aux Contact Out
When an output is not active, the Common terminal will be electrically connected inside
the N-111 to the Normally Closed terminal. When the output becomes active, the
connection between the Common terminal and the Normally Closed terminal will be
broken, and a connection will then be made inside the N-111 between the C terminal
and the Normally Open terminal.
The Aux Output terminals are electrically isolated from the N-111 and from each other,
and can be safely connected to external power sources or grounds.
