Specifications
Following are specifications for the PSSCCNA ControlNet adapter.
ControlNet Adapter - PSSCCNA
Expansion I/O Capacity
• Maximum of 63 modules
• Maximum of 5 Rack Optimized connections (for digital modules only)
• Maximum of 25 Direct connections
• PSSCCNA backplane current output = 1.0A maximum. See the list below for backplane
current consumption for each I/O catalog number and the current consumption for each
of the modules connected to the PSSCCNA. Verify that it is below 1.0A.
• Backplane current can be extended beyond 1.0A with a PSSSE24A Backplane
Extension Power Supply. The PSSSE24A can supply up to an additional 1.3A of
backplane current.
• Multiple PSSSE24A modules can be used to reach the maximum of 63 modules.

Power Supply Specifications
Power Supply
Note:
In order to comply with CE Low Voltage Directives (LVD), you must use either a
NEC Class 2, a Safety Extra Low Voltage (SELV) or a Protected Extra Low Voltage (PELV)
power supply to power this adapter. A SELV supply cannot exceed 30V rms, 42.4V peak
or 60VDC under normal conditions and under single fault conditions. A PELV supply has
the same rating and is connected to protected earth.
