Connecting an aux output
Each contact output is made through three connections on the contact block. The
connections for each aux contact output are arranged in four groups of three terminals,
one group for each aux contact output. In each group the terminal on the left (looking at
the back of the unit) is the Common terminal on the form C. This terminal is labeled ‘C’.
The center terminal (labeled ‘NC’) is the Normally Closed contact, and the terminal on
the right (labeled ‘NO’) is the Normally Open contact.
To connect an external device to an aux contact out on the CX-6p-PoE, use two wires,
16-24 AWG in size. Strip about ¼” of the insulation from the end of the wires before
inserting them into the terminal block. While pressing in the small orange tab adjacent
insert the wire into the hole. When the tab is released the wire will be held securely.
Aux Contact Out
When an output is not active, the Common terminal will be electrically connected inside
the CX-6p-PoE 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 CX-6p-PoE between the C
terminal and the Normally Open terminal.
The Aux Output terminals are electrically isolated from the CX-6p-PoE and from each
other, and can be safely connected to external power sources or grounds.
