Meaning of terminals of TBX distributed input/output modules

Terminal	Comment
+C	TBX DMS 16P22 modules only. This terminal, connected internally to +S (+24 V DC) serves as the common for 2 sensors. It is not protected against short‐circuits.
+C	TBX DMS 16P22 modules only. This terminal, connected internally to +S (0 V DC) serves as the common for 2 preactuators.
+CA	This terminal, connected internally to +Os (a +24 V), is not protected against short‐circuits.
-CA	This terminal, connected internally to -Os (0 V DC) serves as the common for 2 preactuators.
Cn, n+1	On relay output modules, this terminal serves as the common for 2 relays.
+Cs	This terminal, connected internally to +Is (a +24 V DC or a +48 V DC), serves as the common for 2 sensors. It is not protected against short‐circuits.
-Cs	This terminal, connected internally to -Is (0 V), serves as the common for two 3-wire proximity sensors.
+Csn, n+1	Only for modules with wiring check function. This terminal, which supplies a +24 V DC protected against short-circuits, serves as the common for 2 sensors. It comes from +Is (+24 V DC).
In	Input.
I/On	TBX DMS 16P22 modules only. This terminal can be configured as an Input or an Output.
+IS	+ input supply terminal: +24 V DC or +48 V DC
-IS	- input supply terminal: 0 V.
NC	Voltage free terminal: Not Connected.
N1	The two N1 terminals are connected together internally. They only exist on modules with 12 or 16 relay outputs.
On S	Output
+OS	+ output supply terminal: +24 V DC
-OS	- output supply terminal: 0 V.
+Osn, n+1	TBX DMS 16C222 modules only. This terminal supplies two 2A transistor outputs with +24 V DC.
+S	TBX DMS 16P22 modules only. + input and I/O supply terminal: +24 V DC.
-S	TBX DMS 16P22 modules only. - input and I/O supply terminal: 0 V.
+SV	+ module supply terminal: +24 V DC or +48 V DC. This powers the communication module and the I/O interface of the base or extension module.
