Power supply units and I/O interfaces CX1100-0003

One of four power supply modules can be selected for CX1010/CX1020 systems. The power supply of all other system components is ensured via the internal PC/104 bus; no separate supply lines are required. However, the CX1100 components offer further important characteristics that go beyond a pure power supply: an integrated NOVRAM enables the fail-safe storage of process data, an LC display with two lines of 16 characters each is used for displaying system and user messages. The power supplies of the CX system can be changed in the field. The CX1100-0003 offers in addition to the power supply and the three main functions the I/O connection for Bus Terminals (KLxxxx) and the for Extension Box IExxxx type Beckhoff Fieldbus Box modules (IExxxx). The option to connect Bus Terminals or Fieldbus Box modules creates a control system with a very variable, expandable I/O level with large signal variety. The I/O data are stored in a DPRAM, which is accessible by the CPU via the system bus.
