Power and flexibility

    CJ systems can operate on 24 VDC power supply, or on 100 to 240 VAC mains. For small-scale systems with mainly digital I/O a low-cost small-capacity power supply can be used. For systems with many analog I/Os and control/communica- tion units, it may be necessary to use a larger power supply unit.

    Depending on the CPU type, up to 3 expansions can be connected to the CPU ‘rack’, giving a total capacity of 40 I/O units. The total length of the expansion cables of one system may be up to 12 m.
