Modicon backplanes are available in sizes from 2 ... 16 slots. The DIO

Drop Adapter module occupies one slot, and contains a power supply

supply’s capacity is 3.0 A.

1.5.5 Terminal Block I/O (TIO) Modules

Remote sites can be serviced using Terminal Block (TIO) modules.

These compact modules mount directly to a panel or DIN rail, and

TIO modules are available for single-cable layouts only, and are not

applicable for use in dual-cable layouts.

Figure 10 shows the front view of a typical TIO module. Specifications
