Features

The TI545/TI555 CPUs and support equipment comprise a

computer-controlled system that is capable of controlling complex

manufacturing systems. This system performs the same functions as relays,

static control, or card logic control systems. It can detect the change in state

of input signals from such devices as pushbuttons, limit switches, and

analog sensors.

Acting on this information and executing a Relay Ladder Logic (RLL)

program stored in memory, the TI545/TI555 CPU produces output signals to

drive motor starters, solenoids, pilot lights, modulating control valves, etc.

These signals are used to regulate the operation of various pieces of

equipment.
