Part I Basic Operation and Application of SR

Chapter I General Introduction to SR

SR intelligent controller is a new type of programmable controller, being

programmed by the use of Function Block Diagrams. The programming of SR is simpler and

easier to learn than that of a conventional PLC, which uses ladder diagrams and associated

instructions. The design concept, for the SR series products, includes a removable LCD

panel. The program can be written directly into the SR using this LCD panel. After

programming the LCD panel can be retained or removed and replaced with a cover. The cost

to the user can be reduced by multiple use of the LCD panel. The use of a computer is

recommended for more complex control schemes.

Equipped with voice module, SR-VPA or SR-VPD and remote module, SR-RCA

or SR-RCD, SR series can realize telephone remote, wireless remote, voice prompt, auto

dialing and so on functions. Also equipped with extension module, SR-20ERA, SR-20ERD

or SR-20ETD, the inputs and outputs will be enlarged to meet your control requirement.

Mostly one SR machine can be connected with five extension modules and there are 122 I/O

points (74 inputs and 48 outputs) at most.

SR intelligent controls series can be used in local and remote control,

communication, networking and monitoring. SR is widely used in many fields of industry,

commerce, mining, agriculture, home automation etc.
