Expansion I/O interface unit, connects to left hand side of expansion I/O rack, up to 3 expansion racks

CJ1 systems can operate on 24 V DC power supply, or on 100 – 240 V AC 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/communication 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.
