isysNet ControlNet Adapter, Series A (PSSCCNA) E103P7SpecificationsFollowing are specifications for the PSSCCNA ControlNet adapter.ControlNet Adapter - PSSCCNAExpansion 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 backplanecurrent consumption for each I/O catalog number and the current consumption for eachof the modules connected to the PSSCCNA. Verify that it is below 1.0A.• Backplane current can be extended beyond 1.0A with a PSSSE24A BackplaneExtension Power Supply. The PSSSE24A can supply up to an additional 1.3A ofbackplane current.• Multiple PSSSE24A modules can be used to reach the maximum of 63 modules.Cat.
