The CPM NET Concentrator
System Power Module
An Interface Module can only power two I/O modules;
the CPM provides additional power, allowing up to
eight I/O modules of any type to be attached to one
Interface Module.
An Interface Module can support a maximum of
sixteen modules, in which case two CPM modules
would be required for power. This forms a fully
populated system.
Note:
The Interface Module provides power for up to
two I/O modules. If more than two I/O modules
will be connected to the Interface Module, a CPM
Concentrator Power Module is required. It works in
conjunction with the Interface Module to power stations
of up to eight I/O modules. However, the CPM will only
power units that are mounted to
its
left (from the user’s
front-view perspective, this would be the right side of
the CPM).
Installing the CPM
Installation consists of physically mounting the unit,
making the power connections, and grounding the unit.
Mounting
The CPM is designed to snap easily onto 35mm Top
Hat (EN50022) DIN- rails. Snap the CPM onto the
DIN-rail to the right of any module within the NCS
station, then slide it along the rail until the DB25
connectors on the side of the CPM connect completely
with the unit to its left. The CPM can be installed at
any position within a NET Concentrator System.
Power Connections
After mounting, it is time to power the CPM. Attach
20-30Vdc power as shown in CPM Module Figure 16.
The wire gauge requirement for NCS system modules
is 12-28AWG.
Power Sourcing Parameters for General
Locations, Intrinsically Safe, and
Non-Incendive/Type N applications
In accordance with IEC 61010.1 Annex H (all models),
the input terminals must be connected to and/or
supplied from a certified energy limiting Class 2
or a Separate Extra Low Voltage (S.E.L.V.) power
supply separated from all mains by double/reinforced
insulation
